Radion light spill


New member
Question for those who have a radion hanging over their tank. Without being in a canopy what kind of light spill is there? I'm debating if I want to build a canopy or just use some brackets to hang mine over my 40.

It depends how high you mount it. The TIR lenses help direct more light into the tank. I have mine mounted 12 inches about the water and there is slight spill over. There would be very little none if you mount them 6 to 8 inches above the water.

I think it depends more on where you most frequently view your tank from, ie sitting down. I ended up building a box out of acrylic to help with the light spillage, but it also helped with hiding the crap in the back and keep fish from tile surfing!
