The Low-Blue Nightlight comes with a unique amber LED bulb that emits 90% less blue light than ordinary bulbs, making it a perfect choice for people who are prone to tossing, turning, and awakening in the middle of the night. An experiment found that people who woke up in the middle of the night and saw this amber light continued producing melatonin.
Package contains one 120 VAC nightlight fixture and one 120 VAC LED amber bulb (for use in the United States and Canada). The LED bulb produces light only in the amber portion of the light spectrum, with a peak at 589 nm. The LED bulb will not work in automatic on/off night light fixtures, but since the bulb is LED, it will last a very long time. DO NOT use dimmers with 120 VAC LED bulbs, as some dimmers may cause the bulb to fail.
Melatonin is a hormone that your body produces to induce drowsiness and sleep, which usually reaches its highest levels in the body during the night. Researchers have discovered that light causes the body to reduce its production of melatonin, resulting in restless sleep. Two recent studies found that blue light in particular is mostly responsible.
