Where we checked it: uk.boncharge.com ›
Why we picked it
Emits red light with, according to the brand, no blue or green wavelengths. The circadian system (body clock) is least sensitive to long-wavelength red light, so a dim red light is a sensible choice for the middle of the night.
Best for
A bedside or bathroom light for night-time wake-ups and nappy changes
Not for
Reading or general room lighting, as red light is dim and colours look wrong
The details that matter.
