vladimir:Greg, is there an easy way for me to compare the brightness of the Tristar 15 Lighthead say, with the 21 watt HID?
TSandM:The Green Force lights are beautiful, and have a very good system for sealing, but at least as of a couple of months ago, they did not offer a focusable light head.
c555:You are all aying that 18 or 21 watt lights are good, but they are so much more expensive. I will probably get a 10w with a large wreck canister and if i want/need more light I can just get a new 24 watt head. I was thinking dive rite because there are several LDS that sell tham and they have a good product. Any thoughts and I just want to make sure the light heads can be swapped out. Thanks
c555:Manta, I just looked at the green force website. Are you saying that if right now I got a Flll battery w/ 10w HID, I could get a 21w HID if I ever need/ want it, but not with DR? Your lights look pretty good. Does anyone else have an opinion on green force? Thanks
