Quiet, Doesn't generate heat, Therapeutic benefits
I bought this to see if it has therapeutic benefits.  For me it does, I use it for 20 min at a time.  It gives me good energy.  It also provides pain relief for my back.  The other good thing about this bulb is that it doesn't generate heat and it is quiet.  I purchased one of these from another manufacturer and it makes a noise and gets hot.  I try to use the red light several times a day for optimal benefit.  I plan to travel with this bulb, which seems fairly sturdy.
