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
Nice, I think people will be very interested in the gasket when buying this led. Will they be sold separately as well?
Are you planning to sell a version with a warmer color, some 5000K?
Hank can you make gasket for 7mm and 9mm hole reflector also? This is the two most common hole size.
Hank please put oslon white in the Meteor and D4S!
Does anybody know if i use a Sanyo GA in the D1S with oslon white, will it work?
With a flashlight that uses a direct driver like the D1S you need to add resistance, by using a high resistance battery (the GA is still too low resistance/high current perhaps a NCR18650B works) and using long thin led wires if you can get the driver out. If you are handy and smart enough to find a spot for it, you may be able to add an actual resistor somewhere in the current path. Unfortunately Hank’s springs are very low resitance, maybe swap the copper-alloy tail spring for a steel spring. Experiment, keep measuring current and see if you can get to 5A or lower.
I asked him refarding the d4s already. He said the beam doesnt look right. Would be awesome if he can get them in the meteor though. Love the focused beam.
Also Hank, please sell the oslon white centralizers on your store.
Like that you eliminate all the benefits of the low Vf of the White Flat 1mm².
