Due to some silly department requirements regarding weapon lights and training, I can't currently use a WML. I have a Surefire light with a 2.0 Switchback on it.
I can get CR123's from our Station Master/Quartermaster, but I work nights and they don't so I don't always get a chance to grab spare batteries.
I think I want to run a Malkoff with the rechargeable batteries (I will keep some 123s as backups).
The issue I am having is that I don't have a practical knowledge base to make sure I order the right light. I want a single output light with 600+ lumens that will work with the switchback. I am not sure if i need a replacement head or if I should get a complete flashlight.
