While I was at Home Depot this afternoon grabbing some Xmas presents, I managed to grab my lighting setup for my new 30G tank.

I'm feeling pretty good about it considering what I paid...hopefully it's enough to light my tank (20 inches tall).
I picked up a T8 4 foot shop light with a sweet reflector on it. I had planned on using regular shop lights, but didn't want the light blasting everywhere, so this solves that problem - directing the light right at the tank. I paid $34.99.
Then I grabbed 2 different bulbs - both 32 Watt Phillips T8's. I got one 'Natural Sunlight' bulb (6700 colour temp.) and one 'Plant and Aquarium' bulb, which doesn't list a colour temperature.
On my way out, I stopped in the hardware section and got some decorative L brackets to hang the lamp from.
Total cost was around $60. ;D
The window blind is used after 8pm when the tank lights go out but the living room lights stay on.
If more light is needed, I plan to add a fixture with a spiral fluorescent blub.
