  1. Unfortunately a lot of this information, whether it be pro or con seems speculative and on the “holistic-front”. I have to agree that Blue LEDs should be out of the bedroom and possibly moved into the bathroom. This scenario has worked for me.

    For the last 50 days, I’ve been using LEDs in the morning when I shower. I have found that using blue LEDs from 460-490nm, “indirectly” for 10-20 minutes seems to have beneficial results, in heightened alterness and mood. I’ve created a 144 LED board using 460, 470 and 490nm blue LEDs, in no particular order, fabricated a sealed/waterproof acrylic enclosure and have it timer operated. The gradual, ramping on/off of the photocell proved annoying, so opted for a timer to have the “snap” on/off I was looking for, not to mention I can change the timer options easily.

    Although I am happy person, it’s hard to tell if this unit is working but showering in blue light is pretty cool and gives me something to look forward to in the morning.
