Osram Lightify "smart" bulb review / teraodwn

Here is a nice review and teardown of the Osram Lightify smart bulb / wallet draining system:


Supports RGBW bulbs and white bulbs with adjustable color temperature.

He calibrated his spectrometer against the sun…

I read the review and i am pretty impressed. Osram lighting is on of the popular and trusted landing brand.

Thanks for the links, TP!
I had not read this review before, I really like his style, lots of information and measurements but he is also honest about his uncertainties about the method.

The RGBW bulb uses Oslon Square leds for the white, and Oslon SSL150 leds for the colours, the tunable white bulb seems to use DURIS S5 leds.
