This is the LED light that casts a soft warm glow to convince an infant’s circadian cycle that it is still time to sleep. The Harvard Sleep Clinic has shown that biologically corrected light contributes to a good night’s sleep. Unlike typical lightbulbs that provide too much light, which disrupts an infant’s sleep cycle, this light casts 270 lumens of soft white light at a 40-watt equivalency and provides a 25,000-hour lifespan, promoting an infant’s development of healthy rest and activity patterns. Its soft glow provides the added benefit of allowing parents to perform feeding and changing tasks without disrupting their own circadian cycles. 3 1/2" H x 1 3/4" Diam. (1 1/2 oz.)
