This database, originally shared on Reddit [1], provides extensive analysis of 150+ smart lights:

- Specs: wattage, protocols, CCT range, brightness

- White light: CCT deviation, blackbody deviation

- RGB: gamut area, spectral distribution

- Color quality: CRI, TM-30 Rf/Rg (full reports)

- Dimming behavior

- Flicker: waveforms, SVM, Pst LM

- Thermal imaging

Testing uses spectrometers, integration spheres, and LabFlicker meters. Covers brands like Philips Hue, LIFX, Wyze, Nanoleaf, among others.

I've been recently considering changing my GU10 bulbs to the Hue ones, so I find the report useful to compare with Nanoleaf one ([2] and [3]).
