If anyone's looking for an outstanding lighting system, have a look at the Green Force! I just picked up their FIII battery with a 21Watt light head, and it is awesome! I just did a wreck penetration yesterday and the light totally rocks! I've also got one of their reels and it's rock solid too. The Green Force light system is a completely flexible set up and extremely durable. I've heard that the company will even drive a nail through plywood and turn on the lamp to show it's durability! The customer service from Manta is second to none! Here's the website to check out http://www.mantaind.com/ When you check them out say hello to Greg for me!
