Are the units able to be mounted in a canopy? Do they have mounting brackets? Are they full spectrum? How hot do they get? I'm guessing these were on your larger tank that you took down. All your coral looked great in the 60g. How were these lights with Coral growth?
Yes can be mounted with additional hardware. Only the hanging rail is included. Either drill the rail and use screws or, use "U" brackets.
Not full spectrum. 50/50 blue and white.
Cooling fans keep them from getting too hot.
They were on my larger setup for almost a year. Couldn't give a honest opinion about growth. 8 was fighting an algae bloom for almost all of that year that wiped out prob 70% of my corals.
