1
00:00:00,080 --> 00:00:04,612
I have something like five video topics that&nbsp;
have half-baked sorta-started scripts

2
00:00:04,612 --> 00:00:06,388
and it’s driving me up the wall a little bit

3
00:00:06,388 --> 00:00:10,167
so here’s&nbsp;a hastily thrown-together script brought to you 
by a disappointing tript to home depot,

4
00:00:10,167 --> 00:00:11,320
he&nbsp;quipped.

5
00:00:11,320 --> 00:00:16,975
Philips, and this is not sponsored in any way which will become increasingly&nbsp;clear as I get more and more upset with them,

6
00:00:16,975 --> 00:00:21,504
makes what is to me the holy grail of dimmable LED&nbsp;light bulb.

7
00:00:21,504 --> 00:00:25,536
They call the feature I’ve grown to love the “Warm Glow effect”

8
00:00:25,536 --> 00:00:33,529
and the idea is that&nbsp;these can rather faithfully mimic the shifting color temperature of an incandescent light bulb&nbsp;as it’s dimmed.

9
00:00:33,529 --> 00:00:35,072
Here, take a look;

10
00:00:35,072 --> 00:00:36,676
Dimmer, warmer!

11
00:00:36,676 --> 00:00:38,517
Brighter, less warm.

12
00:00:38,517 --> 00:00:40,104
Kinda dim,&nbsp;kinda warm.

13
00:00:40,104 --> 00:00:42,306
Really dim, really warm.

14
00:00:42,720 --> 00:00:49,260
I know I’m old fashioned, but this is exactly&nbsp;
the sort of thing I want my light bulbs to do.&nbsp;&nbsp;

15
00:00:49,840 --> 00:00:52,794
See, back when hot glowy wires were the norm,

16
00:00:52,794 --> 00:00:59,213
a&nbsp;dimmer switch would cause the light output of a tungsten lamp to shift downward
from its 2700&nbsp;kelvin

17
00:00:59,213 --> 00:01:03,186
(or maybe 3000 kelvin in the case of halogen) color temperature

18
00:01:03,186 --> 00:01:07,120
into a progressively&nbsp;warmer-looking color as brightness was reduced.

19
00:01:07,680 --> 00:01:11,253
This happened because the filament was&nbsp;
in fact getting cooler,

20
00:01:11,253 --> 00:01:18,137
and yes the fact that we describe cooler literal temperatures as&nbsp;
warmer color temperatures does rile some folks up a bit

21
00:01:18,137 --> 00:01:20,987
but language doesn’t have to be scientifically&nbsp;precise.

22
00:01:20,987 --> 00:01:22,614
Except, of course, when I say it does.

23
00:01:23,150 --> 00:01:28,110
Anyway, in an incandescent lamp, the apparent&nbsp;
color temperature is a result of the filament’s&nbsp;&nbsp;

24
00:01:28,110 --> 00:01:35,074
literal, actual temperature because the fantastically hot&nbsp;
filament is essentially a blackbody radiator.

25
00:01:35,074 --> 00:01:43,094
We call this a 2700K color temp because that filament&nbsp;
is 2700 kelvins hot,

26
00:01:43,094 --> 00:01:45,550
or 2462 Celsius hot,

27
00:01:45,550 --> 00:01:48,296
or 4400 Fahrenhot.

28
00:01:48,296 --> 00:01:51,826
When you run one on a dimmer&nbsp;
switch and limit the power going to the lamp,

29
00:01:51,826 --> 00:01:58,224
the filament gets less hot, resulting in not only&nbsp;
less light but also warmer-looking light.

30
00:01:58,224 --> 00:02:03,547
Because again, the color temperature is a function of the&nbsp;
filament’s actual temperature.

31
00:02:03,547 --> 00:02:08,790
At very low light levels, the color is almost an amber, not far&nbsp;
off from candlelight.

32
00:02:08,790 --> 00:02:12,235
And when I want to rest my eyes in a dimly-lit environment,

33
00:02:12,235 --> 00:02:15,242
that’s&nbsp;exactly the sorta thing I’m looking for.

34
00:02:15,600 --> 00:02:18,529
If you know anything about my Christmas light&nbsp;shenanigans,

35
00:02:18,529 --> 00:02:24,480
it probably won’t surprise you to learn that my biggest issue with LED lighting&nbsp;
as it was first hitting the scene was that,&nbsp;&nbsp;

36
00:02:24,480 --> 00:02:27,556
even once we got dimming pretty-well figured out

37
00:02:27,556 --> 00:02:31,452
the dimming experience always seemed wrong to me.

38
00:02:31,760 --> 00:02:34,856
Side-note, this isn’t a video on how dimmer&nbsp;switches work,

39
00:02:34,856 --> 00:02:40,081
but as a brief summary dimmer switches repeatedly chop up the AC sine wave as it&nbsp;goes through them

40
00:02:40,081 --> 00:02:44,421
because that’s really the only efficient way to throttle output power.

41
00:02:44,421 --> 00:02:47,726
While&nbsp;that approach was fine for incandescent lamps,

42
00:02:47,726 --> 00:02:53,760
when dimmable CFLs and LEDs appeared, which both&nbsp;
have electronic drivers to control the glowy bits,

43
00:02:54,320 --> 00:02:58,738
well it required some careful circuit&nbsp;
design in order for these new lamps to

44
00:02:58,738 --> 00:03:02,562
A) work correctly with that gnarly chopped up&nbsp;power

45
00:03:02,562 --> 00:03:07,570
and B) interpret its relative choppiness as a desired brightness output.

46
00:03:07,570 --> 00:03:14,269
The fact that&nbsp;dimmable LED bulbs manage to work at all on this wacky power is pretty impressive if you ask me,

47
00:03:14,269 --> 00:03:22,145
although lots of older dimmer switches themselves couldn’t handle the strange load characteristics of these newfangled lamps

48
00:03:22,145 --> 00:03:26,759
and that’s why the dimmability of LEDs is still a sore spots for&nbsp;some folks

49
00:03:26,759 --> 00:03:30,985
as you may have needed to replace some dimmer switches if you had a flickerfest.

50
00:03:30,985 --> 00:03:33,195
If you haven’t looked into this in a long time,

51
00:03:33,195 --> 00:03:39,115
LED-compatible dimmers are pretty cheap these&nbsp;
days and so long as you’re comfortable swapping one out,

52
00:03:39,115 --> 00:03:43,342
I promise the energy savings are gonna&nbsp;
pay for that new dimmer switch pretty quick.

53
00:03:44,000 --> 00:03:48,640
Uh, right, so even once we got dimmable&nbsp;
LEDs working well with dimmer switches,&nbsp;&nbsp;

54
00:03:49,200 --> 00:03:52,440
they never looked right to me at low brightness&nbsp;
levels because,

55
00:03:52,440 --> 00:03:55,732
without getting warmer like an incandescent bulb does,

56
00:03:55,732 --> 00:04:02,637
a warm-white balanced&nbsp;LED starts to look almost… grey when you get down below 25% brightness or so.

57
00:04:02,637 --> 00:04:10,501
It’s nice that it’s&nbsp;less light, but there was no way I could rewire my brain to accept that as anything but “wrong.”

58
00:04:10,501 --> 00:04:15,355
So it was a glorious day when I first laid eyes on the
“Warm Glow” packaging,

59
00:04:15,355 --> 00:04:18,127
saw the little picture&nbsp;Philips put together and realized

60
00:04:18,127 --> 00:04:21,341
“Holy crap they’ve done it. This I’ve gotta try!”

61
00:04:21,341 --> 00:04:24,685
and I bought&nbsp;a couple, took ‘em home, and was hooked.

62
00:04:24,685 --> 00:04:30,096
Finally, an LED light bulb that truly looks and behaves like&nbsp;
an incandescent lamp,

63
00:04:30,096 --> 00:04:34,390
bringing all of the tech’s advantages with virtually none of the downsides.

64
00:04:34,390 --> 00:04:37,949
While you weren’t looking, I put a Warm Glow bulb in here.

65
00:04:37,949 --> 00:04:38,819
That’s right.

66
00:04:38,819 --> 00:04:39,735
This guy.

67
00:04:39,735 --> 00:04:40,664
Is.

68
00:04:40,664 --> 00:04:41,684
Not.

69
00:04:42,752 --> 00:04:45,020
Incandescent. That was a really smooth reveal.

70
00:04:45,280 --> 00:04:47,424
That was quite some time ago.

71
00:04:47,424 --> 00:04:51,624
Philips has been&nbsp;making these for… gosh close to a decade now I think,

72
00:04:51,624 --> 00:04:56,935
I know for a fact I bought a bunch back in&nbsp;
2016 including this one right here.

73
00:04:56,935 --> 00:05:00,737
And I had a pretty good guess into how they worked -

74
00:05:00,737 --> 00:05:07,367
it seemed&nbsp;like there were probably two sets of diodes,
perhaps balanced at 3000 kelvin and 2100 kelvin,

75
00:05:07,367 --> 00:05:12,453
and at full brightness they mixed together to make what looked like 2700 kelvin.

76
00:05:12,453 --> 00:05:17,181
Then, as the bulb&nbsp;dimmed, it would first lower the output of the cooler LEDs,

77
00:05:17,181 --> 00:05:22,341
gradually shifting the color temperature down,
until finally only the warm set was lit.

78
00:05:22,720 --> 00:05:25,920
It could then still get a bit dimmer&nbsp;
but that’s as warm as it’ll get.

79
00:05:26,720 --> 00:05:32,080
Lately they started producing filament style&nbsp;
bulbs with the warm glow effect which reveal that,&nbsp;&nbsp;

80
00:05:32,080 --> 00:05:34,911
sure enough, that’s exactly how this works.

81
00:05:34,911 --> 00:05:41,943
You&nbsp;can even see when the bulb isn’t lit that two of the filament sticks are a bit paler than&nbsp;the other two.

82
00:05:41,943 --> 00:05:47,980
In case you weren’t aware, modern white LEDs are actually not too far off&nbsp;from fluorescent lighting tech

83
00:05:47,980 --> 00:05:53,907
as the diodes emit blue light - or, as is increasingly common,&nbsp;
near-UV light - which is then converted

84
00:05:53,907 --> 00:05:58,813
by a phosphor mix sitting on top of the diodes into&nbsp;
other wavelengths of light.

85
00:05:58,813 --> 00:06:05,212
When that's all combined it produces a white light - at least, one&nbsp;
that’s good enough for our eyes, anyway.&nbsp;&nbsp;

86
00:06:05,440 --> 00:06:10,080
Generally, LEDs with a warm color&nbsp;
temperature have a very deep yellow,&nbsp;&nbsp;

87
00:06:10,080 --> 00:06:12,663
almost orange phosphor coating,

88
00:06:12,663 --> 00:06:18,686
and as you&nbsp;move up the color temperature scale the phosphors become an increasingly pale yellow.

89
00:06:18,686 --> 00:06:24,409
Take a look at one of these video lights, which have a matrix of warm white, cool white, and RGB&nbsp;diodes

90
00:06:24,409 --> 00:06:26,771
and it’s obvious which diodes are which.

91
00:06:27,200 --> 00:06:32,044
So, as predicted, at full brightness all of the&nbsp;filament sticks are lit.

92
00:06:32,044 --> 00:06:39,387
And as the light is dimmed, at first only two of the filament sticks
(the&nbsp;cooler-looking ones) start to get dimmer.&nbsp;&nbsp;

93
00:06:39,600 --> 00:06:47,397
Since, as that happens, an increasingly&nbsp;greater proportion of the total light&nbsp;output is coming from the still-bright, warmer filasticks,

94
00:06:47,397 --> 00:06:50,460
the&nbsp;mixed light output appears progressively warmer.

95
00:06:50,640 --> 00:06:52,448
At least, to a point.

96
00:06:52,448 --> 00:06:58,165
Once the cooler filasticks&nbsp;are completely extinguished, 
it can’t get any warmer but it will get dimmer.

97
00:06:58,165 --> 00:07:01,622
In fact these will just&nbsp;barely glow if you want them to.

98
00:07:01,622 --> 00:07:06,383
At first I thought this idea would be a poor fit for these&nbsp;
filament-style bulbs,

99
00:07:06,383 --> 00:07:12,175
and it does look a little weird 
to have only half of them doing anything at&nbsp;low brightness,

100
00:07:12,175 --> 00:07:18,054
but given how this style of bulb isn’t exactly easy to stare at anyway, 
I think&nbsp;it’s fine.

101
00:07:18,054 --> 00:07:25,280
And actually, once they started making these the last meaningful differences between&nbsp;
incandescent and LED were all but eliminated.

102
00:07:26,000 --> 00:07:31,008
I have been extremely pleased with these LED&nbsp;
lamps since I first discovered them.

103
00:07:31,008 --> 00:07:35,934
They’ve performed excellently and flicker-free on nearly&nbsp;
every dimmer switch I’ve tried,

104
00:07:35,934 --> 00:07:42,560
although I have had some flickering on certain switches but it generally&nbsp;
happens only at very specific brightness values.&nbsp;&nbsp;

105
00:07:43,363 --> 00:07:49,888
Also, they have a great light quality to them; 
not&nbsp;exceptionally good but certainly better than&nbsp;average.

106
00:07:49,888 --> 00:07:54,978
And in all this time, if memory serves,&nbsp;
I’ve had exactly three failures:

107
00:07:54,978 --> 00:07:59,314
The worst one was a bule that just died about a year after I started using it.

108
00:07:59,314 --> 00:08:01,277
And then there's this one.

109
00:08:01,277 --> 00:08:07,910
Uh, this one seems to have some sort of wiring problem because at full brightness, it can get a little flickery.

110
00:08:07,910 --> 00:08:14,434
And I just discovered (literally just now) that at low brightness settings, it's not doing the dimming effect correctly.

111
00:08:14,434 --> 00:08:17,563
All of the filmanet sticks are working together.

112
00:08:17,563 --> 00:08:22,991
And then the other failure, I think, was just a hilarious manufacturing boo-boo.

113
00:08:22,991 --> 00:08:28,322
I&nbsp;have a frosted glass bulb version of this bulb and it works absolutely fine but…

114
00:08:28,322 --> 00:08:29,695
it doesn’t get warmer!

115
00:08:29,695 --> 00:08:38,311
It's just a&nbsp;wee bit cooler-looking than the package mate it came with so I think that one got made with all-cool filasticks.

116
00:08:38,311 --> 00:08:41,048
I’d show it to you but I can’t find it.

117
00:08:41,167 --> 00:08:41,667
Oops.

118
00:08:42,156 --> 00:08:50,490
Aside from those three failed lamps, there is literally just one other problem I’ve ever had with these and&nbsp;it’s, again, minor.

119
00:08:50,490 --> 00:08:52,661
But… weird.

120
00:08:52,661 --> 00:09:00,833
I have a few of these PAR20 lamps in recessed cans and all of&nbsp;
them handle the transition from cool to warm a little bit wrongly.

121
00:09:00,833 --> 00:09:03,471
If you start out at full&nbsp;brightness, they’re perfect!

122
00:09:03,471 --> 00:09:10,356
But if you dim them down to a certain point, even though it starts&nbsp;out mixed correctly the bulbs will slowly just…

123
00:09:10,640 --> 00:09:15,384
stop outputting any light from the cool&nbsp;diodes and go full-warm.

124
00:09:15,384 --> 00:09:19,920
It took me a while to realize this was happening because&nbsp;
it occurs over a period of several seconds

125
00:09:19,920 --> 00:09:25,040
and they all do it in precisely the same&nbsp;way - I have four of them on the same switch&nbsp;&nbsp;

126
00:09:25,040 --> 00:09:27,016
and they behave identically.

127
00:09:27,016 --> 00:09:33,492
In fact I’ve&nbsp;got another pair on a different switch from a different manufacturer and yep, same exact thing.

128
00:09:33,492 --> 00:09:41,415
In&nbsp;fact that assured me it wasn’t the switch drifting a bit as I thought, it’s definitely a flaw in&nbsp;that bulb’s driver design,

129
00:09:41,415 --> 00:09:47,179
but since it’s really only a problem around a relatively narrow dimness&nbsp;band, I’ll give it a pass.

130
00:09:47,179 --> 00:09:50,048
It’s just… pretty weird.

131
00:09:50,048 --> 00:09:54,000
Now, I said that I’m making this video&nbsp;
thanks to a disappointing trip to Home Depot.

132
00:09:54,320 --> 00:09:57,114
In my area, and maybe this is nationwide, I&nbsp;dunno,

133
00:09:57,114 --> 00:10:02,704
the different hardware stores seem to have exclusive deals
with certain lighting brands.

134
00:10:02,704 --> 00:10:08,908
My&nbsp;Mostly Midwestern Mega Merchandise Mecca, Menards, 
doesn’t sell Philips bulbs at all.

135
00:10:08,908 --> 00:10:12,080
They sell mainly&nbsp;Sylvania - and they’re gonna come up later.

136
00:10:12,640 --> 00:10:17,288
I think Lowe’s sells mainly GE bulbs from&nbsp;
what I remember.

137
00:10:17,288 --> 00:10:22,847
And wherever else you might find a light bulb
tends to have a mishmash of&nbsp;whatever, really.

138
00:10:22,847 --> 00:10:30,480
Anyway, the important thing is that the Orange Store has been the place I needed to go&nbsp;to get these or really any Philips lighting products.&nbsp;&nbsp;

139
00:10:31,040 --> 00:10:35,565
And I made a trip to the Orange Store to get a few&nbsp;of these
for some new lamps of mine

140
00:10:35,565 --> 00:10:38,385
and there were none to be found.

141
00:10:38,385 --> 00:10:44,335
No shelf space in that entire store was devoted&nbsp;
to my favorite, fantastic Philips flight bulbs.

142
00:10:44,800 --> 00:10:47,010
No matter, I have Internet.

143
00:10:47,010 --> 00:10:51,366
That was&nbsp;pretty fruitful but the pickin’s are getting increasingly slim.

144
00:10:51,366 --> 00:10:55,742
There are nowhere near&nbsp;as many varieties available as there used to be,

145
00:10:55,742 --> 00:10:58,557
and a ton of what shows up is out of stock.

146
00:10:58,960 --> 00:11:03,760
Not long ago Philips was putting this tech into&nbsp;
pretty much any kind of lamp you could think of,

147
00:11:03,760 --> 00:11:07,868
from your basic A19 things, to candelabra-type&nbsp;
bulbs,

148
00:11:07,868 --> 00:11:10,066
frosted floods and PAR lamps,

149
00:11:10,066 --> 00:11:13,437
and even GU10 halogen replacements!

150
00:11:13,437 --> 00:11:20,095
In fact,&nbsp;they even sold those fancy LED trim retrofits meant to go in can lights
with the Warm Glow&nbsp;effect.

151
00:11:20,095 --> 00:11:22,276
I’ve got some of ‘em and they’re great!

152
00:11:22,560 --> 00:11:27,063
But these days? Well, they seem to be an&nbsp;
endangered species.

153
00:11:27,063 --> 00:11:30,409
Even Philps’ own website isn’t helping things.

154
00:11:30,409 --> 00:11:35,846
Yeah, they still have a page for&nbsp;
the product, but you click on the link to browse and…

155
00:11:35,846 --> 00:11:37,513
well this is useless.

156
00:11:37,513 --> 00:11:43,297
Lots of these are&nbsp;clearly not Warm Glow capable - anything daylight balanced surely isn’t,

157
00:11:43,297 --> 00:11:49,408
and looking through the&nbsp;filters on the left - yep, there’s nothing there specifically for this feature.

158
00:11:49,408 --> 00:11:52,256
So what in the heck&nbsp;is goin’ on?

159
00:11:52,256 --> 00:11:55,615
It can’t just be you weirdos who like daylight-balanced lighting,

160
00:11:55,615 --> 00:12:01,569
I mean plenty of soft&nbsp;white bulbs are still for sale and any remotely nice one will be dimmable.

161
00:12:01,569 --> 00:12:04,400
It’s pretty much just&nbsp;
the contractor grade stuff that isn’t these days.

162
00:12:05,040 --> 00:12:06,664
Well, I don’t know.

163
00:12:06,664 --> 00:12:08,065
But I can guess!

164
00:12:08,065 --> 00:12:14,408
There&nbsp;is of course the whole global supply chain stuff we’re still dealing with but I&nbsp;don’t think that can quite explain this.

165
00:12:14,408 --> 00:12:18,151
As recently as January I ran into&nbsp;
a couple of Home Depot stores

166
00:12:18,151 --> 00:12:20,346
and they both had a solid selection.

167
00:12:20,346 --> 00:12:26,778
Although&nbsp;I’ll be honest I got inklings of trouble since I couldn’t find a ceiling fan bulb with Warm Glow

168
00:12:26,778 --> 00:12:28,694
which was why I went in there in the first place.

169
00:12:29,280 --> 00:12:33,360
I feel as though since the Orange Store&nbsp;
had just six months ago committed a good&nbsp;&nbsp;

170
00:12:33,360 --> 00:12:38,220
section of the light bulb aisle to these&nbsp;
bulbs that supply chain stuff is unlikely.

171
00:12:38,480 --> 00:12:45,146
What I think is far more likely to be the case&nbsp;
is that dang smart stuff all the kids are into&nbsp;these days.

172
00:12:45,146 --> 00:12:47,567
I think it was an inside job.

173
00:12:47,567 --> 00:12:50,253
[whispers angrily] 
Hue&nbsp;did this!

174
00:12:50,561 --> 00:12:57,865
Philips has definitely been pushing their Hue line of smart whatevers (and plenty of&nbsp;non-Hue smart whatevers it seems)

175
00:12:57,865 --> 00:13:02,957
and while they coexisted in harmony with Warm Glow for quite a&nbsp;few years,

176
00:13:02,957 --> 00:13:08,094
I’m thinking Philips is gonna make the folks like me
who are just a little bit too&nbsp;anal about our lighting

177
00:13:08,094 --> 00:13:11,337
invest in something like their “tunable white” bulbs.

178
00:13:11,337 --> 00:13:15,338
Actually, I&nbsp;can’t tell if they get any warmer than 2700K,

179
00:13:15,338 --> 00:13:20,717
so I might even need to get one of those full color&nbsp;
ones and get all fiddly with an app or some junk.

180
00:13:21,200 --> 00:13:24,868
Now lest you think I’m going into&nbsp;
this future all kicking and screaming…&nbsp;&nbsp;

181
00:13:25,440 --> 00:13:27,259
well I am. A little bit.

182
00:13:27,259 --> 00:13:32,542
But I actually have a&nbsp;lot of smart lighting stuff and have for years,

183
00:13:32,542 --> 00:13:37,924
but I am on team “smarten the switches, not the bulbs.”

184
00:13:37,924 --> 00:13:42,400
I have bought a grand total of two Smart Bulbs in my entirely life,

185
00:13:42,400 --> 00:13:44,279
one of which never got used.

186
00:13:44,279 --> 00:13:50,383
You can find&nbsp;a really old video of mine where I went into home automation stuff back in like&nbsp;2017 -

187
00:13:50,383 --> 00:13:52,240
oh actually it was December of 2016,

188
00:13:52,880 --> 00:13:53,990
holy cow.

189
00:13:53,990 --> 00:13:59,417
And in it I talked about my Z-wave dimmer&nbsp;switches,
all of which I’m still using by the way!

190
00:13:59,417 --> 00:14:06,646
Z-wave and Zigbee are two communications protocols&nbsp;
made specifically for home automation stuff,

191
00:14:06,646 --> 00:14:14,692
and the really neat thing about those protocols is that none&nbsp;
of my smart switches or sensors even know what the Internet is.

192
00:14:14,692 --> 00:14:20,820
My entire smart home has one&nbsp;device connected to the internet, 
not counting smart speakers,

193
00:14:20,820 --> 00:14:25,280
and that’s the hub which actually&nbsp;
processes commands and coordinates all those switches.

194
00:14:26,320 --> 00:14:32,933
That’s the last I’ll speak on the...&nbsp;matter, though as the smart home landscape
is in the process of changing,

195
00:14:32,933 --> 00:14:35,437
and&nbsp;hopefully to something simpler and better.

196
00:14:36,000 --> 00:14:42,999
I just wish Z-wave and Zigbee were more&nbsp;
widely understood as the internet-optional&nbsp;ecosystems that they are.

197
00:14:42,999 --> 00:14:48,449
Needing a&nbsp;hub is actually a very good thing,
especially when it comes to network security,

198
00:14:48,449 --> 00:14:50,738
but nobody ever communicated that very well.

199
00:14:51,200 --> 00:14:54,678
Still, I’m not anti-smart bulb, for what&nbsp;it’s worth.

200
00:14:54,678 --> 00:15:00,708
Installing a light switch can be intimidating
and most smart switches need&nbsp;a neutral wire to function,

201
00:15:00,708 --> 00:15:04,504
which many older homes didn’t run through the switch boxes.

202
00:15:04,504 --> 00:15:08,556
And indeed&nbsp;some rather new homes as I’ve recently discovered.

203
00:15:08,556 --> 00:15:13,282
But all I’ve ever wanted with my home&nbsp;automation,
at least in the realm of lighting,

204
00:15:13,282 --> 00:15:16,085
is to have control over brightness.

205
00:15:16,085 --> 00:15:20,622
And since&nbsp;a light switch is usually in control of at least a few light sockets,

206
00:15:20,622 --> 00:15:26,465
it was MUCH cheaper&nbsp;for me to install smart switches than it was to buy smart bulbs.

207
00:15:27,280 --> 00:15:33,120
Anyway, while I don’t care to have&nbsp;
control over the color of my light bulbs or anything like that

208
00:15:33,120 --> 00:15:37,360
I do want them to mimic incandescent&nbsp;
lights as closely as possible,&nbsp;&nbsp;

209
00:15:37,360 --> 00:15:42,880
and the Warm Glow bulb was an elegant - and&nbsp;also pretty cheap! - means to that end.

210
00:15:43,600 --> 00:15:48,971
The new tunable white options are&nbsp;interesting… but here’s the thing.

211
00:15:48,971 --> 00:15:52,814
I never want daylight balanced lighting in my&nbsp;home.

212
00:15:52,814 --> 00:15:55,166
I know that lots of people find it useful,

213
00:15:55,166 --> 00:15:59,573
and I can see the value of a light bulb&nbsp;
which shifts the color temp throughout the day;

214
00:15:59,573 --> 00:16:03,867
being daylight balanced when the&nbsp;
sun’s up, and nice and warm when it’s not.

215
00:16:04,560 --> 00:16:08,647
For me personally, though, that just doesn’t&nbsp;
have much value to me.

216
00:16:08,647 --> 00:16:13,178
I know not everyone has enough natural light in their home to do&nbsp;this but,

217
00:16:13,178 --> 00:16:16,759
I generally don’t need the lights on at all when the sun is up.

218
00:16:16,759 --> 00:16:24,948
And to be honest,&nbsp;on dismal overcast days I actually find the warmth of incandescent-balanced&nbsp;light to be soothing and cozy.

219
00:16:25,440 --> 00:16:31,028
For that reason, a bulb with daylight and&nbsp;
soft white diodes would be half wasted on me.&nbsp;&nbsp;

220
00:16:31,440 --> 00:16:37,920
I suppose if it had a super-warm set of diodes, too, and&nbsp;
could still do a warm-glow-like effect

221
00:16:38,323 --> 00:16:44,320
that would be neat, but once you get that complicated you&nbsp;
might as well just make the thing a smart bulb.&nbsp;&nbsp;

222
00:16:44,320 --> 00:16:47,446
And that’s why I appreciate these so much.

223
00:16:47,446 --> 00:16:52,173
It’s a&nbsp;cheap, simple, and elegant tweak to the dimmable LED concept,

224
00:16:52,173 --> 00:16:57,680
adding that subtle but very important&nbsp;
effect back into a modern, efficient light bulb.

225
00:16:58,240 --> 00:17:00,595
That’s all I was ever asking for,

226
00:17:00,595 --> 00:17:06,473
and dangit&nbsp;if we’re gonna lose this option to smarter, connected light bulbs I’ll be upset.

227
00:17:06,473 --> 00:17:09,293
And that's why I bought all these and stocked up.

228
00:17:09,293 --> 00:17:09,868
Philips,

229
00:17:09,868 --> 00:17:11,680
YOU ARE NOT TAKING THIS AWAY FROM ME

230
00:17:12,320 --> 00:17:13,851
Oh, right, Sylvania.

231
00:17:13,851 --> 00:17:15,720
I said they were gonna come&nbsp;up.

232
00:17:15,720 --> 00:17:19,705
For a short while, Sylvania was copying this idea.

233
00:17:19,705 --> 00:17:25,167
They called it “premium dimming” or something like&nbsp;
that; I only remember seeing them a few years ago,

234
00:17:25,167 --> 00:17:28,671
and I never bought any to compare to Philips.

235
00:17:28,671 --> 00:17:31,503
There are a few new-old-stock options out there,

236
00:17:31,503 --> 00:17:34,286
but it doesn’t look like they’re still in&nbsp;production.

237
00:17:34,286 --> 00:17:35,222
Again.

238
00:17:35,222 --> 00:17:36,730
Boo!

239
00:17:36,730 --> 00:17:42,400
I’d be curious to know if people just don’t understand what&nbsp;
this feature is or knew to look out for it.

240
00:17:42,960 --> 00:17:47,392
There are enough people that just don’t care about&nbsp;
color temperature at all - I mean,

241
00:17:47,392 --> 00:17:51,966
if there’s one thing that offends me more than a daylight-balanced&nbsp;
light bulb in a bedroom,

242
00:17:51,966 --> 00:17:56,783
it’s mixed color temperatures in the same room (or worse, fixture)

243
00:17:56,783 --> 00:18:01,214
Yet there’s a ton of folks out there&nbsp;who truly don’t care about that.

244
00:18:01,214 --> 00:18:02,974
Maybe they can't see it.

245
00:18:02,974 --> 00:18:08,016
I dunno, I don’t know how they can look past a fixture riddled with a&nbsp;
hodgepodge of different color lighting in it but oh well.

246
00:18:08,016 --> 00:18:08,852
They do.

247
00:18:09,120 --> 00:18:11,468
Are these light bulbs for everyone?

248
00:18:11,468 --> 00:18:16,021
No. If you&nbsp;don’t like warm lighting, they’re definitely not for you.

249
00:18:16,021 --> 00:18:20,560
But for those of us somewhere in&nbsp;
between fuddy-duddy and smart home enthusiast,

250
00:18:21,360 --> 00:18:22,776
they’re great.

251
00:18:22,776 --> 00:18:26,772
Philips, if you're listening, please don’t stop production of these.

252
00:18:26,772 --> 00:18:29,828
I&nbsp;hope this is just a supply chain hiccup, but

253
00:18:30,400 --> 00:18:32,513
I’m honestly not holding my breath.

254
00:18:32,513 --> 00:18:37,111
Whoever was first responsible for these, thank you so much for your efforts.

255
00:18:37,111 --> 00:18:40,620
I truly have never&nbsp;been happier with a lighting product.

256
00:18:40,620 --> 00:18:47,157
And, I’ve converted a fair share of LED skeptics by&nbsp;
convincing them to try a Warm Glow bulb.

257
00:18:47,157 --> 00:18:51,752
These are really so close to incandescent dimming in their behavior and appearance,

258
00:18:51,752 --> 00:18:54,320
and if that’s your jam these are your bulbs.

259
00:18:54,880 --> 00:18:56,432
Anyway, that’s all.

260
00:18:56,432 --> 00:19:03,648
These bulbs have come up in&nbsp;the past a few times on the channel but I’ve never bothered making a video specifically about&nbsp;them.

261
00:19:03,648 --> 00:19:06,348
And frankly, I wasn’t planning on it.

262
00:19:06,348 --> 00:19:12,065
But now that it looks like they might be an endangered&nbsp;
species, well I mean I couldn’t just sit here and do nothing!

263
00:19:12,065 --> 00:19:18,436
I suppose it’s very possible that&nbsp;dimmer switches are just far more of a niche thing than I realized.

264
00:19:18,436 --> 00:19:21,647
Certainly I can think of&nbsp;plenty of environments without them.

265
00:19:21,647 --> 00:19:26,789
And, uh, now that I think about it,
I imagine most rental apartments&nbsp;don’t offer them.

266
00:19:26,789 --> 00:19:29,001
So maybe that’s what’s going on here.

267
00:19:29,001 --> 00:19:33,280
Smart bulbs are a nice way to add dimming,&nbsp;
remote control, and more with little hassle.

268
00:19:33,920 --> 00:19:39,079
Still, Philips was putting this tech in to such&nbsp;
a wide variety of products not that long ago

269
00:19:39,079 --> 00:19:42,529
that I think dimmers can’t be *that* niche, can they?

270
00:19:42,529 --> 00:19:49,080
Oh, and I didn’t even&nbsp;mention the really irritating thing which is that, now that I mostly have to buy these online,

271
00:19:49,080 --> 00:19:54,338
I’m not getting those great time-of-sale rebates 
my utility offers on LED bulbs.

272
00:19:54,338 --> 00:19:57,269
It’s a&nbsp;good thing these have proven to be so reliable overall.

273
00:19:57,440 --> 00:20:02,100
Oh and might I suggest, if you’re looking to add&nbsp;
some dimming in your life,

274
00:20:02,100 --> 00:20:04,727
you should look at these plug-in dimmers for lamps.

275
00:20:04,727 --> 00:20:07,694
Sure, they don’t&nbsp;help with any permanent lighting in your home,

276
00:20:07,694 --> 00:20:11,104
but a few lamps here and there can&nbsp;
make a big difference to a space.

277
00:20:11,104 --> 00:20:13,480
Plus, lots of these have smart functions!

278
00:20:13,480 --> 00:20:17,257
I’ve been using a Z-wave enabled dimmer for this video.

279
00:20:17,257 --> 00:20:20,320
Usually I try to think&nbsp;of some sort of real ending before I c

280
00:20:21,221 --> 00:20:23,763
♫ endangeredly smooth jazz ♫

281
00:20:25,520 --> 00:20:28,961
They call the feature… that’s the&nbsp;wrong box!

282
00:20:28,961 --> 00:20:30,276
You did this to yourself.

283
00:20:30,560 --> 00:20:35,400
We call this a 2700K color&nbsp;temperature because… (laughs)&nbsp;&nbsp;

284
00:20:38,000 --> 00:20:40,371
You gotta pick it up a little higher there, buddy!

285
00:20:43,040 --> 00:20:45,183
That’s exactly how this happens.

286
00:20:45,183 --> 00:20:49,811
You can even see&nbsp;when the bulb isn’t lit… why did I say “happens?”

287
00:20:49,811 --> 00:20:51,778
That’s not what the s… that’s not what it says.

288
00:20:52,000 --> 00:20:56,880
And in all this time, if memory&nbsp;serves, I’ve had exactly two failures.&nbsp;&nbsp;

289
00:20:58,000 --> 00:20:59,765
I just remembered a third one.

290
00:20:59,765 --> 00:21:04,572
And as I made a trip to the Orange Store to get a few for some new lamps of mine.

291
00:21:04,572 --> 00:21:08,325
Well… that’s not the words that are there.

292
00:21:08,539 --> 00:21:09,074
[fart sound]

293
00:21:11,138 --> 00:21:14,516
Man, I forgot to move the frame for that blooper where I bonked the lampshade.

294
00:21:14,516 --> 00:21:17,430
That's gonna haunt me forever.

295
00:21:17,430 --> 00:21:19,748
OK, well not for that long.

296
00:21:19,748 --> 00:21:22,551
