Yep, works with single or dual, same way.
All clear and thank you for your answer.
What bin is the XP-L HI in this light? And how long do you get in turbo?
About the bin, they don't seem to publish this info, so hard to tell, but I have the HD version anyway, but I'd guess the HD version is a V6 bin in CW tint.
For turbo, I see nothing said anywhere on the site or in the manual about a turbo timeout, or temperature regulation. I'm thinking they don't have one, but didn't test for it on my HD version.
The momentary boost feature mentioned in the OP is the mode where you hold down the button for the LED to be on at max/turbo. Once you let go, the LED goes off.
My Turbo tactical feature is very defective, it could stay on a minute then go out while holding the switch down, then next time it might just be a flash and out, they have driver issues.
Apparently they are designing a new light and driver and are asking for input but there seems to be little to no interest apparently,
Just hit 2,000 lumens on a simple resistor mod on the M12, details here: https://budgetlightforum.com/t/-/27258/160
