driver for XHP35 HI?


The entire L2 flashlight with XHP35 HI Smile

i’m ready to launch L6 with XHP35 HI ,
the original reflector of L6 is not suitable .
manufacturer is designing new reflector and gasket

This is going to be awesome. Be a great addition to the collection.

Hi Simon,

Can you please give us some more information about the XHP35 HI driver?
Is it a new developed driver from your usual supplier or does it come from KD?
Will it also work 1S (1× 26650) or 2S (2×26650) only?
What is the maximum current it can apply to the XHP35 HI?
What diameter sizes of the driver can you offer?

Thank you!

2A output ,diameter 30mm ,

only runs on 2*26650

what’s the max intensity of BLF GT?

i got a L6 reflector today ,it’s bad ,
i use L2 reflector ,i got 160000CD if XHP35 HI runs on 2A current

(the bin of XHP35 HI is D4 50E)

Okay, so it’s not possible to boost to 12V with only one battery. Sad I guess Kaidomain’s H1-A will still need some tuning for providing 1.5A to the XHP35HI from a single cell. But I see that Sofirn will soon launch the C8G (1× 21700 with XHP35 HI, SMO and 2.000lm). In my opinion the Convoy L2 makes much more sense with XHP35 HI. The L6 is quite a large light for this little amount of lumens (max. 2.000lm), its small reflector diameter in comparison to its length and its moderate power consumption. The XHP35 HI is – to my mind – for throwers and the L6 is more or less an allround-like flashlight but no thrower, perfect for XHP50.2 or XHP70.2. Just sayin’… Wink

According to Jensen567's figures the H2-C still did well at “2A” gear, but pay attention to the already low efficiency at that point (1S input with R075 + R075 sense resistors). Since high mode uses a 60 second stepdown you may try an R100 over the stock R050 (2.25A maximum), but beware of the low efficiency risks, high current losses in switches, springs, etc.

If I were Simon I would go to driver designers and manufacturers and tell them to “stop complaining and make an outstandingly powerful driver, this is for enthusiasts”.

boosting to 12V with only one battery can be designed,But the efficiency is too low,

The BLF GT has 800 to 1200kcd. Depends on how good batch one get.

Simon, just so you know, Richard at MTN Electronics has designed a Boost driver that works with one or two cells and delivers 2.3A to the XHP-35. This is good for over 2000 lumens in your C8+. Smile Perhaps you should work out a deal with Richard?

For what it’s worth, this same driver of Richards also excels in the L2, amazing lights these 2! Big Smile

Oof that would be super expensive.

Maybe a special BLF edition at 70-80$US?

I put a 3v XHP50.2 in my L2 @12A (single cell). it’s a nice light, easy to focus. just guesstimating by eye, CD is a little higher than stock, but quadruple the lumens.

About the anodizing, my l2 came like it was wrapped in sandpaper compared to the super smooth ano from the S2+‘s

In my experience with modding the L2, the XP-L HI will give the most throw even over the XHP-35. Sufficient to say though, the XHP-35 comes close and gives more total output in the process. Significantly more light.

I have a machined finish L2 with XHP-35 HI using a prototype boost driver and it really seriously rocks. Big Smile (~2300 lumens? Edit: From notes, 2246 lumens at 266.75Kcd for 1033M throw) Run time on a single high discharge 26650 is similar to what a pushed XP-L HI will draw, the extra lumens come in very handy. I also have a black L2 with extension tubes and 4 26350 cells utilizing a tweaked LED4POWER driver to run the XHP-35 at a maximum, it too does a very good job and run time is sufficient for me. I do like the short configuration of the L2 the most though and the machined finish light is just exceptional, jewelry grade. Love Thanks Simon! Thumbs Up

Edit: FWIW a sliced and diced SST-40 also rocks the L2. Just saying… (careful, this one has bond wires!)

Edit: To add, a modified L2 with XHP-70.2 also impresses, just not so much in the throw department. I built one for my Bro-in-Law that he loves, something in the 7000 lumens range. He’s a hunter and uses it regularly, fights my nephew over it all the time! lol

Can I buy drivers on aliexpress or banggood. I want to upgrade convoy L2 with XHP70.2. Thank you

I don’t know of available drivers that will supply the optimum current to the XHP-35 as far as Banggood or even on Aliexpress. The drivers I have used are from members of this forum. One in the US and one overseas. LED4Power’s drivers can be configured to use 4 cells to power the 35, these require extension tubes on the L2 to allow the use of 4 26650’s or a normal 2 cell tube set-up can make use of 26350’s with shorter run times. The US made Boost driver can use one or two cells to power the 35 to 2.3A or so, these are the more expensive but more compact option. This latter comes from Richard at MTNElectronics.

He has new options I suppose. I haven’t looked at his drivers for 12V use lately, bet he could shed light on it though if asked. Wink

Is there an L2 extension tube available separately? I’ve seen pictures of an L2 that comes with one that looks like it’d screw into the L2/L6:

Asking because I just got an L6 and it’s great, but surprisingly it’s smaller than I’d hoped for. Would love to be able to add an extension tube or two and swap the driver for a 3S or 4S one to have a proper maglite form-factor replacement with modern internals!

How about using sst40 shave dome on the l2 ? 200kcd easy.

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!!

I am waiting for the driver with 2 cell for Convoy L2. It works with xhp 50.2 or something similar for about 2400 lumens.

Unlikely, as the XHP35 is only available in a 12V configuration, which would require the use of a boost driver. The XHP50 and XHP70 are also available in 6V configurations, which is what Simon is using here. Powering a 6V emitter with two cells in series is relatively straightforward. Developing a 12V boost driver would be considerably more difficult.

i will supply XHP35 driver for L2 flashlight soon Big Smile

This would be awsome, but 1000mah is a bit low. You would get better lumems and lux number with a sst40. 2000mah minimum for the 12v xhp35

Sometimes being a newb is the best part of a hobbie

Whats wrong with the reflector? Is the opening to wide and it sits to high? People have done it on here already.

although the diameter of L2 reflector is small than L6, but it’s more suitable than L6 ,i campared them several times ,
L2 reflector can get more LUX
