I've got an older Dive Rite can light that I picked up and not sure if it's 10w or 20w. It uses 12volt 2.9 AH sealed lead acid batteries. The MR11 lightbulb says 20w but on the diveriteexpress website it talks about converting it from a 10w HID light to a LED ???? Any ideas or knowledge of these lights? I think it's called a "wreck light" but it has no part/model number on it that I can find. Thanks guys, Bell47
