Here is my old one with XP-E R4
And here is the one I just bought…. Fenix claims it’s an XP-E R4 from the website serial# look up but it doesn’t look the same to me… besides I thought they were disco…
By the way my name is Brad, been lurking for awhile, haven’t found any info on this emitter being used in the E21 my beloved tank so I thought I’d ask the pro’s. On a side note packaging is the same as my old one with XP-E with max 170 lumens… So what do you think guys….
