Tanghy, that is a rare combination to ask for. It can be done...how about a complete light?
The head is new. Everything is new. The setup is just like the thread describes. The light will run on a CR123A battery. The BUT is that Mike wants to sell a complete light. The KL4 head/K2 would be on a Vital Gear FB1 body that takes a CR123A battery.
