90 degree. It's hanging about 8-10" off the water. I'm really happy with this fixture. I've seen light fixtures running Cree LED's but the coverage was splotchy. Nothing against Cree. Maybe it would be even better with them. But for the $$ I'm impressed. The pictures do no justice. I can't wait to get it repaired so I can see what it looks like under actinics. I think that driver got fried when it took a dive in the tank I'm happy with the service from Reefbreeders too. Logan has answered numerous emails and is very patient. This is the Photon Nova A4 fixture. It measures 11.25x11.25 made for 24-30" cubes.
