I used a Power Sun 160w for 12 months, had no problems whats so ever, although i dont know how much UV it gave towards the end. Unfortunately 160w Power sun are no longer available, otherwise i wouls have stayed with it.

I have just 2 weeks ago changed to a 160w Mega Ray bulb, touch wood no problems so far, other than i have had to raise the height, as it seems to get hotter than the power sun ever did.
