Hello Simon!! apart from keeping our pockets empty LOL, is there an interest from your behalf of making a helmet light for mtb or mounted on the front of a bike, thanks!!
Hi Simon,
I saw l21a on xhp35hi already available ! This is running on single 18650/26650 cell, how about luminosity and distance of the flashlight ? I’m right now ordering it
The L21a runs on 1 single 21700 (i bought one recently)
It does NOT come with an extension tube. (It doesn’t come with any accessories actually, not even a lanyard…)
You’re right. I just read the group-buy description again. I don’t understand why, because the SST40 can take 2x26650, which is higher in voltage than 1x21700.
Sky Lumen has a modded version of the L2 with SST-40 on 2x26650 for 280kcd. If I understand this correctly, it’s a buck driver (DriverVN4), based on the spec of the SST-40 you provided?
@Simon. Looking at the XHP35 driver, can I just confirm that its 2.3A at the output and single cell only (i.e., won’t work on 2 cells)?
Would it file down enough to fit an L2 (~21mm)?
Two of my lights (L2 and S11) have XHP35 HI and are using the H2-C 22mm 1.5A from KD, so your driver is very interesting.
