Light spread of 2x70W MHs over 36"?


Recommended Posts

I have an open-back canopy that sits 5.5" above the surface of the tank, so 6.5" from the top of the surface of the water.


Is it feasible to retrofit two 70W MHs into a 36" canopy for a 40 gallon tank?


I plan to do it according to this thread:



The Brinks fixtures are pretty deep themselves (~4-5"?), so I'm afraid it'll limit the light spread of the bulbs, especially since the fixtures are only 6.5" from the surface of the water.
