I have 3 250W pendants mounted in my canopy on my new reef build. I'm looking into Actinic Supplimental lighting now. I really love VHO lighting for some odd reason, and was going to do some retrofit kits, but now I'm thinking I might try out LED.
My main question is, how many LED's would I need to have good supplimental lighting?
I've been looking at these units from Rapid LED, which have a 48" heatsink, and 24 LED's. I would buy 2 of them and place them on either sides of the halides. Would 48 LED's do the trick?
