Custom SkyRay King SRK Driver

Any chance on making a driver that can be run from 12VDC? I’d like to use a SRK on my son’s dirtbike for a headlight since he likes to ride a little past dark.

Please tell us that this is something you plan selling? I don’t think you stated you would? And how much would such an intricate driver cost?

My biggest gripe with my SRK is the lack of a medium mode. The question I guess is how much is a medium mode worth for my SRK.

Gosh. I don’t have a SRK but want this driver… What’s wrong with me :stuck_out_tongue:

thats me. im waiting to make sure i have a driver in hand before i buy a SRK

Wow! Excellent work tp. Like everyone else here, I’m anxious to purchase a couple.

I’m in for one, aswell.

(I don’t have a SRK yet, but once things are clear, I’ll get one. The only thing that kept me from buying one was the stupid stock driver …:wink:
Do you have a reliable source for SRKs?)

P.S.: Is there any chances of getting a driver like this for the Kung? If so, I would go crazy :smiley:

For a Kung, you would need to add a separate 8x7135 board for the fourth LED. These are most easily made from a single mode Nanjg 105C driver board.

Any Plans on an 8 * 15 AMC7135 Driver for the http://kaidomain.com/product/details.S022097 ? :)

Nope, it;s a multi-cell light… not compatible with AMC7135 chips…

My 2x18350/8x7135/6v MTG2 light is shocked to hear that it shouldn't exist :O

Should work with any 3.x V LEDs. You could parallel the outputs and drive a single LED at 6 or 9A.

One note on SST-90. It has a fairly high Vf even when driven at only 3A (3.47V after ten seconds or so). An XM-L is right around 3.2V at 3A, XM-L2 is 150mV or so higher.
The result on and SST-90 will be an early drop-out of regulation.
At 6A, the SST-90 Vf is 3.65V.
Note: These were tested on actual emitters I had mounted on a heatsink.

can’t wait until it finished :slight_smile:

It depends on how much quality you want and if you'll swap the emitters and MCPCB's.

The CNQ/FFL SRK is considered the highest quality and comes with XM-L2 U2's. That might even save you money if you reflow them onto better stars. This is the way to go if you want the best SRK you can build.

I believe the Fandyfire UV-S5 is the highest quality SRK clone from Fasttech, but you'll probably want to replace the LED's and stars.

Fasttech has less expensive SRK clones. From what I gather, compared to the real SRK, the big differences are the clickie may not be as reliable and the threads aren't as smooth. If you just want the form factor and the driver, I think this is the way to go.

Another option might be the Supfire M6. It might use the same 46mm driver, which will make installing texaspyro's driver a perfect fit. The bad news is Supfire can't give us a solid answer, so it might actually be a 50mm driver, which I think will be MUCH more difficult than trying to install a 17mm driver in a 22mm pill. The M6 also uses old emitters. There's currently a group buy that has the M6 at $33 shipped. This could be a very nice choice if texaspyro is willing to make a wider version of this driver and if the emitters and stars are upgraded.

You texaspyro are a god, I and I am sure my fellow flashers really appreciate what you are doing, I’m defo in for 2 as soon as ready, hope it comes with a instruction sheet!!
Keep up the awsome work, and thanks.

@leaftye: Thanks for your answer, it helped a lot!

The machining tolerances on the latest batch(es) of SRK clones are horrible. Parts aren't concentric, meaning there will be a thick side and a paper thin side. And the threads don't mate correctly, some of them you can 'walk' the head off the battery tube threads without rotating it like normal. The o-ring on the battery tube doesn't touch the bore in the head because it's machined oversize, etc. and etc. some more...

Is that from specific vendors or everyone?

I have no idea, but as often as the suppliers change things without notice even if you had a 100% accurate definitive list of the good ones and the bad ones at this moment in time, next week it could all change again and you'd be right back where you started, playing the lottery.

Consistently, the good ones are the gold UV-S5 from FT, or the ones from fancyflashlights/CNQG (they carry both the good ones and the clones, but which is which is clearly listed).
