I'm not sure if you mean a full hood covering the entire top or just a lamp housing.
I made a lamp housing with black plastic. If you search under my username for an ODNO thread I posted some pictures.
I found some quarter inch thick sheeting at a surplus store. New material was unreasonably expensive and if I didn't get the surplus plastic, it would have been wooden.
The plastic appears to be some sort of PVC. I wasn't sure initially and didn't know what kind of adhesive to use. I therefore used black machine screws and tapped each hole. It also makes access to the inside easier. I think self tapping screws would have worked OK also.
The material I used cut nicely on a table saw. I would think plexiglas would be too brittle. ABS might be a good choice.
I thought the matte finish of the plastic I found was attractive and of course it's waterproof. Properly finished wood likely would have worked well too.
