one positive thing I can say is that for the 3 or so hours that the non-DOA bulb worked, it was decent (not as strong as a lower rated wattage UV bulb however, so the mfr may be overstating the wattage on these as well as making them poorly)Avoid.

These things really glow.

Coming from a college kid at Oklahoma State University this product was a hit and one of the best things i could've bought

and I really like the energy efficient, happiness that I can bring my children
