I went to the local hardware store, bought two standard light bulb mounts with screws to connect electricity, two blue party builbs, some electrical cord and a plug. I wired the two bulb mounts together, then from the one I ran the electrical cable and attached the plug. I mounted them inside my hood and added a timer. If I remember right the bulbs were either 7 or 15 watt bulbs. It creates this simple little blue glow inside my tank. Nothing too bright, but good enough to see some of the night life in the tank. Total project was around $15 - $20.
