Canopy Design Help

Alright, here's my first draft of the draft...Right now I'm thinking 1/2" plywood sides and top, the boards you see on the outside are 1x4 trim, and all the boards on the inside are 1x2 except the corner pieces, which will be from scraps left over from the 1x4s. The round things are approximations on the (T8) bulbs.

The boxes with the letters represent the electronics...A) 12v Power Supplies, B) Electronic Ballasts, C) Switch box (3-4 gang).

First, some pics of just the hood:

The back corner...wanted to show how the wood "slots" in together:

I didn't include the wires, the Lip Stay, or the Hinges in these diagrams...once the design is set the hardware will be easy (piano hinges are like long butt hinges and=common sense use, and the Lip Stay will fit where it fits to accomplish it's job).

Any comments or suggestions on the rough draft? Want any other pics of it to get a better idea of how it works?
 
thats a long wait, during that time im sure you will think of other things you might wanna add (dont know what though since i think it has just about everything)

Heres a stupid question: With the top fully open wont it throw the balance off more to the back??

Yes, opening it will throw more weight toward the back, but that's why A) I'm trying to design it to only open to about 65* (as shown) instead of a full 90*. and B) using a "Lip Stay" to help as another support for some of the weight to balance forward.
 
Just a couple things...

The electronics (ballasts, bulbs, etc) will produce heat and inside an enclosed hood it will be a lot of heat! You need ventilation. Mounting the ballasts/power supply on the backside/outside of the hood will help and lessen the weight on the top of the hood. I'd at least consider vents in the top and a small fan would probably help too.

Why does B need to be hinged? It looks like it's just a "filler" piece. If it's only moved for major maintenance, why conect it at all? Flip A back and remove B and set it aside??? Just an idea :)
