Question about P60 drop-in, AloneFire 501B

Hi everyone,
Can I put 1 mode drop-in on 3 mode flashlight AloneFire 501B?

If it takes a P60 drop-in, then yes. Levels are controlled by the drop-in with input from the switch.
One thing I wonder about. The description says: * Switch Mode: Zoom In
What the heck does that mean?
Anyway, I have a bunch of lights that use p60 drop-ins. I have switched single and multiple level units around lots of times.

Thanks! :slight_smile:
