Convoy L2 XHP50.2 K2-1C outdoor performance

Driver is in production ,i’m not sure the date

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 :slight_smile:

I thought the L21A runs on 2x21700, while the L2 runs on 26650, or 18650. The M21A runs on 1x21700, and is the 21700 version of the C8+.

Is there a new L21A running 26650?

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…)

L21A runs only 1*21700 or 1*18650 w/adapter.

26650 only on L2.

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.

Simon, do you have any indication/comparison numbers of throw and Lumen of the L21a in SST40 vs XHP35 ?

The sst40 is a 3V LED, also the driver is only suited for 4,2V

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?

I’m not familiar with Vinh his drivers, Simon (Convoys owner) does not support 2x 26650 for the SST40 (at least not the L21a)

@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.

Yes, that should work, the driver is just released, single cell driver for XHP35.
It should fit, since the L21a (21700 version of the L2) is the first to be introduced with this driver.

it runs on 18650/21700 battery ,
170KCD, 824meters

it runs on 1pcs 21700

L21A XHP35 820meters
L21A SST40 720meters

22mm ,it only can be installed in L21A

Boy does THAT sound like a challenge… :smiley:

Just ordered 2. I love a challenge :wink:

Can l2 throw 2000lm all the time?
Can it work on 21700 battery?

Or is there any other convoy flashlight under 50€ which can do this?

For 21700 , there is the L21A version with XHP35
I don’t know if it has temperature stepdown, otherwise removing the NTC on the driver will disable it.
