I was going to go for 3 of these over my tank but I didnt want the hassle of fabricating a bracket up for them and I dont think I could live with the light spill.I’ve just wired up one of these to see what it looks like.

Perhaps not quite as cool white as I’d like but I’m sure it will be more than bright enough for the 60L Nano I have in mind. Just a matter of working out a suitable way of mounting it over the tank.
