Hi all! Quick question... I seem to remember that with the original 800 lumen UBR-A-BK output was capped at 400 lumens when running on 123A Primaries versus the rechargeable battery.

Is there such a limitation with the newer 1,000 lumen UBR-B-BK?

Just asking as I'm struggling to find any such information on the Surefire website and I'm quite sure that it was mentioned with the original light.

Cheers!

The UBR-B-BK 1000 lumen version has been updated to run at a max output of 675 lumens when running on 123A's. My source is the Surefire user manual since I'm a UBR-B-BK owner. Hope this helps.
