I have never come across a commercial hood that allows a serious amount of lighting to be installed. Hence I constructed my own. As I am seriously impared in the drawing area I will have to describe my design in words. It does allow full access to the tank surface.

My tank is constructed with 6"x0.5" pine boards. The uprights internal measurements allow 1/4" all around the external tank dimensions. I have fitted 1" battons to the uprights to allow these to sit on the tank top and support the hood.

The hood lid is oversized front to back by 4", this gives a lip that is used as a stop board when the top is fully upright. The top is hinged at the back to allow the 90 degree movement of the lid. I use a simple pivotted piece of 1x1 to lock the lid in the upright position. On the lower part of the rear upright I attached a shelf for my foods etc. Doing the lid this way has allowed me full access to the whole of the tank surface and the lighting is fully 'getatable'.

You will have to make a few slots at the rear to allow for cables, and filter inlet / outlet tubes. I did taper the outer uprights front to back for aesthetic reasons.

Despite lashings of polyurethane varnish I did get slight warping of the timber. Not too serious but it does let a little light escape at the front edge.

I hope that this is of some help.
