Why we picked it
WarmGlow bulbs get warmer (more orange) as you dim them, like an old filament bulb, and this one has a colour rendering index of 90 so skin and food look natural. Warmer, dimmer evening light is the change best supported by sleep research.
Best for
Bedside and living room lamps you dim in the evening
Not for
Ceiling lights that need a lot of brightness
