Can't speak to reliability or effectiveness but they are very damaging to the eyes. I thought it would be good for my new office but it would be a big NO. I don't know, maybe my eyes just weren't used to this color, but it didn't calm me down at all. As if I were in the sun and had to partially close my eyes. I had to switch to a regular lightbulb and now no problem. I tried anyway. I will definitely be returning these lamps. It may work for some but not for me.
