Why Your RGB Bulb Is Useless for Sleep Lighting

That AliExpress RGB bulb you bought for circadian lighting? It's physically incapable of giving you usable red light. This episode unpacks the LED physics that kills brightness in color mode, why amber beats red for sleep hygiene, and what the 2025 Manchester meta-analysis actually says about blue light. We compare RGB, RGBW, and tunable white bulbs, recommend specific Kelvin targets, and name real products that work — from Philips Hue to Waveform Lighting amber bulbs. No firmware update will fix this. The fix is a different bulb category.
