Which driver for 4 X xp-g/,2 X 18650 torch??

[4D223]

Hi guys, as the title says I am looking for a driver/s for my Romisen RC-t5 which died. I have 4 xp-g led's and run 2 x 18650's. I have used the search function extensively and even poured through "Torch Boy's" LED driver guide. My problem is that I am a "dumbkopf" when it comes to electronics and it makes no sense at all. I have looked through the driver guide on Cutters website as well. Please help!!

Great thread. Another part of the question. We are not going to use batteries to power this so have an endless supply of power. Can the led's/driver handle this? The drivers that come with these are not able to keep up and get very, very hot within an hour of use.

Combine driver and heat sinks and all should be alright?

Thank you for the replies,
"Tx101", I have read through "download's" info and I think I am beginning to understand a little. Where can I buy these 8 X 7135 driver described? Is it a KD/DX item or from a member in the marketplace?
"trip", I'm not sure what you mean about the "endless power supply"

This one will work fine: http://www.dealextreme.com/details.dx/sku.26106 efficiency up to 89% ...

btw. "dumbkopf" -> it is spelled like this: "Dummkopf"

txt101 and I did a similar setup using 2 x 26500 and 4 XPG R5 driven by Download's 2.8A driver in a 2s2p setup. Each emitter gets 1.4A.

Using a battery with charging system, no batteries to exchange so constant power all the time.

The problem we are having is using the driver that comes on these drop in lights they are only intended to be used for 1-2 hours max.. Wanting to use these for 5-10 hours.. So need have a good driver and guessing a heat sink to keep it all cool?

Here is what we had from the first version.

KD/DX do sell the boards but it might be quicker if you buy from
Shiningbeam.com

Errr .... I got a bit carried away and build three of them, 2 x XPGs and a r2 version as well :o

Maxflex is another driver option.

This has been awesome guys, thank you all for your help. I have ordered a "shining beam" p7/mce driver as it is identical to the one shown. If I can work out how to post photos when the build is done , I will. Cheers, Pete.:wave:
