I have a Surefire M600 DF on an AR. Currently, I’m activating it with a UE07 remote switch and running the Surefire 18650 battery that came with the light. I’ve noticed that the battery seems to drain very quickly while the light is not in use. I carry a handheld 18650 powered light daily and regular use it. That battery lasts multiple times longer than the one in my WML. Same thing with a different WML on another gun that doesn’t have a remote switch. I took this AR out today. At the beginning of my range session, the light worked when I checked it as part of loading up. By the end, the light was dead. I wasn’t using the light during the range session otherwise. Are remote switches prone to parasitic drain on the batteries? If that’s the issue, I’ll just go back to the clicky tail cap.
