I have a incan Surefire E2E that I would like to put an LED head on, but I really don't want to break the bank on it, so I'm looking for a cheap light with a led head that will screw onto the E2E body. After a few searches I found some old posts mentioning a Romisen light that would work, but the links posted didn't work so I don't know the models. Anyone know of a cheap light that will work? Also single mode would be preferred.
