What lights use 17670 batteries?

Many SF lights use them, including my old style 6P.



I put one in my U2, works great. Is it true that the U2 loses some output when you use a 17670?

They won't fit in my P3D :shrug:

Fenix P3D? I tried inserting one(17670) in my colleagues (P3D), it doesn't fit. Is this a 4rd party body/modded? TQ

I remember seeing test data for these used in the L4, and the data showed that there was a slight loss in output, but the numbers were still so close, you'd have to be a robot (with light meter) to notice. I'd think it'd be the same for the U2.

should also mention that some of those will take 18650 cells as well, the rest of the chart shows which ones will... but 17670 cell would work fine too, you just get less runtime.
 
Most 18650 lights should work just fine with a 17670 as well provided it's not drawing very high levels of current.
