How are “Daylight Lamps” different from standard white LEDs with the same power? What gives them the therapeutic properties?
In: 17
Daylight lamps mimic daylight. LED lamps are just bright. The difference is the frequency of the light emitted. Daylight lamps will include some UV light, and other wavelengths that more traditional lamps lack. This promotes things like vitamin D production, and as such can have significant health benefits, most notably for things like SAD and depression in general. In addition light does help regulate circadian rhythm so the lights can be used to help adjust your sleep schedule, though as far as I’m aware this is a claim and I haven’t seen any supporting documentation (because I haven’t looked). But the other benefits are noted, and seem to be real.
They are not simply lamps with more blue light, they have a physiological benefit.
