Making a 5g refugium in my sump and need an inexpensive LED light for it. Total length is 15" so figured 12-14" would suffice. I have an office LED desk lamp (variable from 4500 to 6500k), and was thinking of retrofitting a similar lamp to the refugium. I am worried about the heat transfer. Does anyone have any recommendations as to what they have used in the past. I would like a strip light instead of a LED screw in bulb as I can keep the strip closer to the refugium and prevent extra light from scattering to the rest of the sump.
