That would be wild. Where does one buy the driver?

Definitely interested in the 371 driver with amber/red secondary led.

Although I would probably change my copper 18500 back to an 18650 if I used that driver so that I could use 2 18350s as an added option for maximum output.

I would definitely go for Serge's driver. I had one of the new Oveready V5 lights and loved the programming interface.

This should also take care of the worries of over current on the switch I would think.

I think so, max input is 5A, and the driver bucks the voltage to deliver more current from the driver to the LEDs with 2-cell setups.

That would be wild. Where does one buy the driver?

I ordered mine directly from Serge at Lux-RC. Be ready for sticker shock though, and shipping sucks.

I'm not sure if 2-cell will be possible with the current design as the McClicky spring would have to be pretty compressed as the light is sized for unprotected cells and not longer cells.

In that case, I'll probably stick with the Qlite driver and 18500 body currently selected. Thanks. :)

 

[quazzle]

to be more accurate 371D limits the upper current at 6amp per cell. Normally it's about 5.5A which guarantees fully regulated 17W with one cell and 35W with two cells (in afterburner mode with available only with 2S)

You could always cut down the clicky spring a bit...

Yes, but with my lack of practical skills I'd probably mess it up! ;)

I have just played with my freshly arrived BOSS 70 light with the 371 driver. Its great but having one of them is probably enough for me. :thumbsup:

Would there be any interest for Serge's 371D driver? It is the same driver/XP-L 4000k combo that is in the Overready Wasp and BOSS.

They offer extremely good efficiency in all modes (90-97% efficiency per Serge), current controlled, secondary red LED, bounce sensor, fully programmable, on board temperature regulation, and wide voltage range 1-2 cells.
I'm thinking of offering these as an option in addition to the standard H17F. They are very expensive though, so additional cost would be +$50 for that setup.

Driver would be nice... XPL 4000k would be AWESOME!!

 

[write2dgray]

Yes on Serge's driver. Love the secondary red LED, very practical in my daily uses.

For me I'm exactly opposite. Love the driver but didn't like the re-domed XP-L emitters. The Nichia emitters with this driver would be the cats meow though.

These are actually the 4000k XP-L, not the 4500k XP-L re-domed. Nichia would be nice, but Serge said they are very difficult to get ahold of in Russia.

Oh ok, if this is the case I'll have to stick to Dr. Jones driver as I just didn't care for the XP-L leds in the Oveready V5 E series lights and I wouldn't want to take that chance again.

I'd be down for trying one of these in my 18500 Cu build if you have one available?

An update on the 371D, I'm going to send some 219Cs to Serge to have made up into drivers, and a couple for him to test as he is interested in ordering a bulk order and offering them himself, which would simplify future orders of the drivers.

Engine setup is a solder bridge between the negative trace (I'll de-solder the negative pin on the next ones) and the pill, and there is positive lead to the brass contact. The board itself is recessed into the pill to center it.

Update on 2-S setup, it can fit but it will compress the McClicky too much to work with an unprotected 18650. On the other hand, holy smokes can this driver generate heat with 3A to each XP-L in the 30W afterburner mode. I'm not sure what Serge will set the 219Cs to max, but they'll still be bloody bright as well.

My personal preference in playing around with the programming is to err on the conservative side with output, so 3A is my preference. For perspective that is about 11W-14W in the options, and the max off 1S is 23W, or about 7A to the LEDs. Impressive stuff.

Good info, thanks!

Looked back through the thread for pics of Al-Bronze, perhaps I missed them but didn't see any.

I lifted this from your google album, are the two to either side of the copper AL-Bronze?

I'm still on board for Serge's driver if the Nichia option is there.

I just received my 219Cs from Richard, and they will be going to Serge to be made into 371D boards.


The rightmost light is Al-Bronze with a nice patina on it, the opposite light is my BeCu.
This image below shows fresh machined vs patina.

Oh, and a point about how stable the Al-Bronze patina is once it develops, here is the picture from two weeks before the picture you posted of the same lights, same order.

For some reason, I can't see the pics you posted..

I think I fixed it. Google photos is weird about embedding images.
