exactly the same principle as with the GU10 Warmglows, 4 big bright leds and one small warm one in the middle. And also fades between them. Only downside is that they flicker sometimes on a cheap 15 euro dimmer, but that's to be expected.
Thank you for this video and teardown, I saw this bulbs and was wonering how they work. I like your pipe lamp, how do you attach the lamp socket to the tube?
Thanks for this video! Looks like a decent quality light! Not only in terms of light characteristic, but also build quality! I have one of these "WarmGlow" lights of Philips in an E14 socket version. Unfortunately, with that light, the PWM dimming is very visible (at least to my sensitive vision). If you would film that light with camera, you would certainly see a lot of 'banding' scrolling through the image. Good to see that the E27 version does not seem to suffer from this effect, possibly because of the component you mentioned. I reckon the E14 formfactor is too small to house extra components to reduce PWM effect.
Too bad your camera doesn't have a "white balance" setting that you could lock it in to "sunlight"... so it wouldn't adjust itself. That would give us a true idea of the color temperature change. BTW... you do realize that there are likely lethal voltages in there... right? You kept putting your hands pretty darn close to the 'live' circuits.
If you look at the reflection over your hand you will see the warmer LEDS actually dim down as you get to full brightness.
Thanks for this teardown! This is some interesting stuff!

Thanks.
that's an interesting lamp you have there

Good job.
Love this. It's something I've been itching to do but I'm chicken, and also too cheap to destroy a lamp!
Were you using a led dimmer in this video, or just an old analog dimmer? Thanks cool video!
+smarchan It's a standard TRIAC forward-phase dimmer made primarly for incandescents
good!!
technology connections sent me

Thanks for tearing up your bulb for the rest of us!
