75 standard. 4 t5 2blue+1purple+1coral+ let reflectors from reef geek as they rate for highest par. Reef geek sent me 4 extra I posed to send back but if interested, I can not send back
I will let you know. So far all I have been able to do is hold the lens over the LED. It definitely focuses the light, but I can;t measure or even see what it looks like until I can find some time to attach it somehow.
