Sorry for the vague info, I don't know if they have a brand on them...but I can tell you this... they are identical to Apollo LEDs. Same manufacturer, same light. 55x3w LEDs per fixture. They are available at Optimum if you want to see them.
I liked the color having seen them on another member's tank, and was lucky enough to be able to see a PAR test before I bought them. I'd equate the color approximately to a Radium. I know that they are available with 10vdc dimming (for use with an Apex), but can't report on that as I bought the non-dimmable ones.
