Smart bulb questions, answered with test data

Answered with the numbers in this database. They update as I test more products.

What is the CRI of smart bulbs?

Across the 119 smart bulbs I measured, the median CRI Re (averaged over their white settings) is 89: 47 reach 90 or higher and 21 fall below 80.

Which smart bulbs dim low enough for night?

15 of 119 bulbs dim to 1 lumen or less at their lowest white setting, which works as a night light. 76 never go below 5 lumens. Sort by dimmest white above to see them.

Do smart bulbs flicker?

Some do. Of 119 bulbs, 36 show no flicker risk, 41 low risk and 40 high risk. I measure percent flicker at full and half brightness on every bulb.

How warm can a smart bulb go?

The median warmest white is 2187K. 32 of 119 bulbs reach 2000K or warmer, which cuts the body-clock signal in the evening, and the warmest white I measured is 1308K.

Can smart bulbs mimic daylight or a sunrise?

76 of 119 bulbs reach a 6500K daylight white, but color temperature alone is not daylight: check CRI as well. For a sunrise routine, scheduling and how low the bulb starts matter most; see how to set up a smart light sunrise.

Which color smart bulbs show the richest colors?

The ones with the widest color gamut. Across 65 full-color bulbs, Rec. 2020 coverage has a median of 77% and tops out at 93%.
