okay there are 2 types of canopys
1- Glass - consists of 2 pieces held together by a plastic hinge. The light you are looking at can be placed on top of this glass without a problem.
2- Box - A box canopy that goes on top of the tank, usually used for diy purposes to install own lighting. The light you are looking at would not need this box canopy.
Also before you actually go with that light look around there are a few places that sell that light for cheaper and there are other lights on the market which can provide the same amount of light and be easy on your pocket.
