If not what would the best way be to fit more light in the plastic hood?
You would have to replace the ballast, but IMO overdriving a T5 bulb gives you practically no useful return.
Couple things you might try:
1. Try a fancy reflector for that fixture. You might be able to hack away at the fixture or just paint the inside with a better reflective surface. T5 reflected gives awesome light.
2. You could copy the type of canopy my girlfriend has. Basically, you've got your tank and a standard canopy, but a "lift" goes between the two. The lift is made out of thin wood and essentially adds about 6 inches of height to the tank. The canopy sits on top (she has fluorescent actinics in it) and in the lift itself, drill some holes in the back and add some generic screw-in compact fluorescent bulbs.
At Home Depot I found some waterproof moguls sockets (well, water resistant when you screw the bulbs in tightly) and some compact fluorescents that gave a blueish light that look *great* in a mini reef. Right now we've got 3 of those and a single 18" actinic in the hood and the light is DAZZLING. We're thinking about adding another fluoro or two and giving a clam a shot.
Let me know if I didn't explain it clearly enough - I can always head over there and take a couple pics.
