With a screen name like that, You CAN'T do it without a light.
I just ordered a UK Fathom pack from my local shop. They lent me lights to try them out. For under $100, you can get a decent main, backup, and tank light, batteries included. Just add buddy and dive. Lots of creatures come out at night. And even at 40 feet in daylight, u loose a lot of light. The light really brings out the colors at depth.Just mho. enjoy
