My mini-GT driver seems to have lost the 7135 part of the ramping after I tried the 2mm2 White Flat (it is still gone with the new led, a dedomed XP-G2). It seems to make little sense if the White Flat with its low voltage was the cause of the damage, but after what you noticed with the NANJG driver I tought it’d be relevant to mention here.
Hoop, do your nanjg drivers still work?
I have a Convoy driver with 9x7135 and 1mm2 white flat in an S8. It works fine.
Good to hear, I did not wish to cause panic, was just sharing my observation, the damaging of the mini-GT driver may not have anything to do with the 2mm white flat.
Both seem dead. Neither work with XP-L HI. They were new/untested prior to this test. Not sure if either had E-switch firmware but I doubt it.
Ah! Yikes! Sorry. I haven’t tried it, and I wouldn’t think an LED could kill a driver like that. 
I didn’t either, and have a 2mm on the way to use with a 7135 based driver.
Hoop. Djozz, given your unfortunate shared experience i thought it prudent to start a new topic:
Hope you don’t mind?
He should just use one of these. Is it really $10 stopping it or is there an issue with driver size and the D1S. He is hopefully redesigingim it a bit for a 21700 anyway.
Ya, just design a whole new light. At least he knows what the people want. A 21700 Oslon compact super thrower. :+1:
Thank you Hank for an update. It’s sad to learn you can’t do it, but I like your openness.
I suggest that you look at Texas Commander driver. It’s in a beta state. And may not deliver the current that you need. But using Led4Power trick of putting the FET on MCPCB should solve the issue and make it easily handle 5A, probably 8A for 2mm² variant as well. You would still have to put the work of taking it out of beta and into production…but it seems you’re more than capable of doing so.
It has to be an e-switch driver for the Emisars.
I think Lexel may have something available.
I’m still waiting for led4power’s e-switch version of his FET CC driver…
But iirc Emisar uses 20mm drivers?
Either way, i’m guessing there are a few people on BLF who would be more than happy to come up with a suitable driver and PCB layout, if Hank can’t find a solution.
Yep, the e-switch is the issue for those drivers. If the driver designers didn't take into account parasitic drain, an e-switch may never work on that driver design.
Again, our ramping UI's should work fine with a 7135 bank + 1, or even without the +1. I got NarsilM working on a FET only driver because the 7135's were constantly getting blown - yes, lots of amps for 16 XHP50's...
Interested. Any idea of the #K? I like NW in the 4000K to 5000K range.
I'll take one!
i`ll take one !
Hank , whats the link to this LED / mcpcb please
Type in LED4POWER. Think they are on their home page.
Here is the code, we have also made some gasket for this particular LED 
Hank where is the CODE ?? i want to order one can`t see it on your site
