Sleep is but a gift to many. When it comes to astronauts there are more than a few reasons where sleep becomes absolutely crucial. NASA has developed a specially-designed light bulb that promotes sleep. This is achieved by encouraging the production of melatonin, the hormone that helps us sleep. The light emitted by this bulb is unlike typical light bulbs that emit high levels of short wavelength ‘blue’ light. This light bulb reduces the blue light by 50% to enable better night sleep. You can use it on your night stand 30 minutes before you fall asleep and if NASA’s claim is to be believed, you will fall asleep sooner than usual.


The bulb is made up of a 12-watt LED that produces the same light that a 60-watt incandescent bulb would shed. This allows for optimal light levels to read and lasts sixteen times longer than regular bulbs. $60.
