Cannon 70watt LED diffuser??? Problems
I have 2 sets of cannons over my 5 foot by 7 foot frag tank. 4 bulbs total 2 blue 2 white
Problem is with them 4th above the tank there is very little spreading of light out towards the edges. I wonder if anyone has heard of any diffusers for these type lights or any other ideas before I go back to Metal halides and t5s????

Did you really expect 4 cannons to light a tank of that size. That is asking a lot!

Wrong light for the application for the size. The spread is tiny on these things, which is how they get the PAR numbers they advertise.
Spread is often overlooked when it comes to LED's.
