Do you have a pic of one of these running on a tank Ian?
I do have a comparison pic I can post.
Here is a picture of one of the acans in our coral bed. On the right side you see what the piece looks like under a ATI Power module running with 4 Blue Plus lamps only (whites were off for the pic).
The left half is the ATI Blue Plus + 1 Reef Brite LED strip.
