Just a quick question. Building my second light trying to save some loot on heatsinks. With recommendations set by @SupraSPL at 25cm2 for each Watt would my calculations be correct that I could run 4xcxb3590 on the heatsink USA 3.5" at 48" long? I wonder if one fan is enough or if two would work better. Any ideas?
