I have tried a couple different Optronic lights.

I have tried the ones listed in this link as "NightBlaster UW-3000" and "UW-500G Submersible Fish-N-Lite / Green Fluorescent Light Plus Halogen Spot Beam" and neither has worked as well as my Q-Beam Starfire II lights. The Starfires will run you ~$13 apiece, which is cheaper than the Optronics and, in my opinion and experience, work better. They are available at WalMart. They're fragile though. I break about one a month.
I hook one light up to a 12V deep cycle and it will run all night long without any significant drain on the battery.
