they are sending me a new one for the one that burned out , But i have yet to put one in my Rhino cage and will not use them . They have a clear lens , no coating and nothing that defuses the light . After the 72 hour brake in it i check it with my 6.2 solar meter at 18'' and it has a small spot 1'' in the middle that's over 350-400 MW of uvb , move even a inch and it only 30-40 MW and few more inches and only in the teens . :s
