Default Lights: Above or On a Canopy?

So what is better, putting the lights directly on a glass canopy on the tank, or hanging them a few inches above the water?

I used to put them directly on a canopy, but now I'm trying hanging them. However, there is a lot of light wasted/leaked out the sides now. Should I go back to resting them on a canopy?

Raising above the tank say 3 inches or so increases the spread of the light, and gets those wide corners. I've mounted all my lights as such, and the plants don't lean towards the center but straight up as usual. Plus, the resting on the glass for me in the past has ended up with a crack piece of glass

I pulled my lights off my glass and removed the glass all together, open water tank has a much more appeal. Seeing the plants from the surface, feeding, trimming, alot of perks.

I've had the same problem with cracking the glass. You should really lift the lights a couple inches to prevent heating the glass. That way, splashing water will not crack your lid.

Maybe I should do a search for this as well, but how have you mounted your lights? I live in an apartment and couldn't mount them from the ceiling, so it would have to be on the tank somehow, or maybe a standing lamp.

I bought a JBJ "vacuum cleaner" light with fans about a year ago before I knew anything. It works great, but it's SO loud. I'd like to replace it when I have the money, and perhaps mount the lights above and go lidless (if my cats will allow it).

Here is what I did to my light to raise it. The legs can be found in any local fish store that carrys the compact lights.

Thanks, Skinns! I will have to check this out. None of my LFS sell compact flourescent (since the good LFS burned down 6 months ago) so I may have to order online.

why dont you build a Hood, It will only cost you $20 or less depends on what size is the tank, i build mine using shoplights its 3.5 inch above the tank and the light is really spreading on the tank
