Why do color-changing smart bulbs get so dim when you switch from white to color mode? It's not just cheap components — there's a fundamental physics trade-off between phosphor-converted white LEDs and direct-emission RGB. This episode breaks down the engineering behind CRI, lumen output, and RGBW architecture, then gives practical advice: use dedicated high-CRI white bulbs for primary lighting and save color for indirect accent strips. We also cover why Matter's unified lighting model fixes the clunky mode-switching problem, and what specs like R9 actually mean for your living room setup…
