booth22:I don't know what happened to Vince's lights, but ours have been great and really bright. We looked at the UK HID, but at $80 a pop for bulbs, I'll stick with my LEDs. Plus Princeton Tec has great customer service (for us anyway) and is great about fixing gear or sending new stuff out. Just another opinion for you....

Problem was flooding. I used these lights for back-up to my UK HID. On three separate occations, the lights flooded without being used. I am meticulous w/ maintenence and orings were completely clean and caps not screwed down overly tight. Each time PT did replace the light, but got to the point I could not trust that the light would fire as a back-up. Have never had a problem w/ my UK light cannon which I now use as a back-up on deeper divers. I just don'e trust the PT lights but will give them a plus for customer service. In the end - you get what you pay for...
