hey guys im wanting to know what driver is good to drive 3 XML-T6 leds almost to there max limit
looking for a budget driver nothing that has to be ordered from china lol any help would be helpful
PS: battery option ? would 2 26650 battery's work ? or ?
Hopefully someone here knows more. The only driver I know of for 3 T6 leds is this one, but it is from china and it must have at least 6V, figure one battery (li-ion) for each emitter?.
Only other way I know of is to use three of the 8x7135 boards, here, here or here, and run the leds in parallel. (many people do this, I won't)
See here. and ask dorpmuller how he did the boards and leds for one 26650.
As Old-Lumens said, the only domestically-available budget driver is the 8x7135AMC. Manafont has a driver for $5.80, and KD has another for ~$14.50. The DRY driver is one that I've used in builds, and it's about $6.
The driver sandwich is the only single-cell option. The others require 2 or 3 cells to provide the requisite voltage.
There is a non-budget option: the Taskflex H6CC, but it's over $30.
i have 3 or 4 of these >>>8x7135AMC but would anyone have a pic on how it gets wired up ?
anyone ?
Rich had a post where he shows how he stacked 3 or 4 drivers. It's post #14 in this thread:

I posted it above, strange it didn't show.
I haven’t tried this one yet, X, but am hoping to use it in a mag or a SAiK SA-305. Have you made this stack yet?
can the slaves be bought at http://illuminationsupply.com ????
THe slaves are just regular 8*AMC7135 single mode drivers. You can also just buy a bunch of the readily available multimode versions and just remove the controller chip (one with 8 legs) from the ones to be used as slaves.
Not yet. Dorpmuller is helping me out with wiring one up, as he has done this one before.
@nitro: The 'slave' boards are just the regular boards with all of the non-AMC7135 components removed. Illumination Supply (Craig) had them in stock, last I looked.
EDIT: JohnnyMac beat me to it.
i think im going to try this because i need one :) i wish we can do a group buy on these driver before they discontinue them
so if this is correct all i need to do is just take off the controller chip (one with 8 legs) from the 2 boards to be used as slaves.
I would wipe everything except the 7135s off the 2 slaves
If you don't mind waiting for China to open up from it's holiday Ric at cnqualitygoods.com has the Dry drivers for 5 bucks a piece that will save you 20 bucks and tons of aggravation trying to get this to work. He has several different versions I have tested the 4 mode with strobe and the 4 mode with turbo I am waiting on the 4 mode turbo with turbo step down timer.
You have to remove the components yourself.
I've been looking this over again & I have tried to contact techjunkie about it. What I see is that not only is the 8 pin controller removed, but also "R1" and "R2" are removed. Then there is a ?Resistor? soldered across two of the contact points where the 8 pin controller was. Looks like it may be more involved and I don't know about different variations of the board. None of the posts I can find describe this removal of rhe resistors and the placement of another resistor where the controller was. The ones I have are the "105C" version. I was going to try to find someone younger, who didn't shake so much, give it a try, since I need something for 3 leds too.
If anyone figures it out please post photos and an explanation.
Sorry, not trying to highjack the thread...
Problem with the DRY driver is it needs 3 cells in series to operate. Stacking AMC drivers will allow 3v-4.2v operation from a 32650 or a Mag filled with standard or NiMH “D” cells or even a triple Li-Ion parallel setup.
i would like to have 3 modes L,M,H and use 1 or 2 26650 battery's if that's possible
I will have this thread finished when I get home from work late tonight. It should answer some of your questions.
