Light at night poses a risks to sleep, even if switched on only briefly. Yet there are times you need clear visibility when the house is dark.
If you have to wake up during sleep time to move about — for the bathroom, or to check up on your child — do it smartly, with LowBlueLight’s blue-blocking flashlight. The special LEDs produce restricted wavelengths of light to ensure that nighttime melatonin is not suppressed and you are able to quickly resume sleep.
SPECIFICATIONS
This hand-held lamp also reduces the chance that your sleeping child wakes up during your nighttime check, or your sleep partner is disturbed as you leave the bedroom and return.
Amber Light vs. White Light
White light from standard flashlights can span a wide range of wavelengths from 400 – 600 nanometers (nm). The blue-green component between 400 – 535 nm can wake you up and keep you awake even after your turn off the flashlight.
By restricting the wavelengths to above 550 nm, peaking at about 590 nm, you avoid this hazard.
