in the $100 range the Big Blue 250 lumen adjustable focus is a great choice. They are very bright, take only 3aaa batteries and have an adjustable beam from 8-31 degrees. Teknitroxdiver mentioned that brighter isn't always better in night diving, agreed. By being able to open the focus on the light you get a nice view without washing out your subject. Don't waste the money on the available glove as you can't change the focus with the light in it. I believe I paid $95 for mine on Amazon just a couple weeks ago. I put a short review of it on here after giving them a try. Another thing, lumen ratings can be deceiving. Some lights lumen ratings are set by the manufacturer, so beware! The big blue is bright and versitile.
