Look What I Made

Any thoughts about the par value of 190? Is that a good par for my tank?

 

At the surface or sandbed?

 

The spec sheet for the led says PAR 190, i don't know how far away the light was tested.

 

That sounds terribly low.

 

190 in parts of the sand bed sounds about right for your low level corals!

 

Yeah, but that's what the emitters spec sheet is saying not his testing. I would expect some overboard rating like 1900 not 190 in the specs. Even if it's Minimum Luminous Flux it's still less than a XP-G @700ma.

Would be nice for someone to get a meter on some of these.

 

Any pics of it turned on over the tank? I have thought about 10w leds but was worried about coverage and light output.
