I thought the L21A runs on 2×21700, while the L2 runs on 26650, or 18650. The M21A runs on 1×21700, 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 2×26650, which is higher in voltage than 1×21700.

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 2×26650 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 2× 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.

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.

Removing temperature stepdown wont solve the problem, cos then you cant hold it in your hand Smile

So tldr:
2×21700 big flashlight with good cooling and over 2000lumens

Size and weight isnt problem

So 2× 26650 version can also work on 2× 21700 without adapters?

Is it able to be cold enought to hold even on full 2400lm mode?

If yes I am going to order one right now Smile

abgx1, why 21700? The Golisi 26650 almost matches a 30T and has 50% more capacity.

You will need to make a tube to prevent battery rattle if you go with 21700’s, roll up thin cardboard or something…

Its working with 21700 great, its not even rattling, as they are very long, so there is enought pressure from springs that they wont move

Just a shout out to Simon for good CS. I placed a small order for TIR lenses and asked for a C8 driver retaining ring. He threw in 2 free ones and got the order to me door to door in 2 weeks. Great service.
