Note that its non-red light flickers with 120 Hz and is, therefore, not recommended for non-red lighting at all. It produces plenty of red light with using only 1W of power. It's a Chinese bulb (as opposed to the Austrian one) however, it has been working for over half a year at least 8 hours a day (that is, night). Strictly red emission-wise, I've found 938939?pt=US_Light_Bulbs&hash=item33691e813b the best. (I haven't tested the somewhat cheaper but non-dimmable bulbs as I couldn't use those bulbs after finding out they flicker - this is why I've ordered dimmable and, therefore, surely condenser (which help in eliminating flickering)-equipped bulbs.) In this regard, I've found LedON's dimmable lights the best.
I've paid special attention to not using bulbs that have ANY kind of 60/120 Hz 'beat effect' (the same thing as fluorescent light does - see the video at, linked from ) I've tested and selected LED bulbs that have pretty much red spectrum components (the best 'warm' white bulbs do this by having additional red emitters in them).
