Unknown SRK 3xLED driver mod

Flashlight Modding and DIY Parts

I have been asked by a buddy to do a simple mod to his SRK to make it a bit brighter

I have replaced the wires to the LED’s as they seemed very thin as standard and I am now thinking of doing the “resistor” mod

I think the ones I want to jump are in the bottom just above the FET in the picture has anyone seen this driver before and is it ok to bridge over?

They are marked 000 on the body of the resistor

LED’s after heavy wires

Wires to LED’s before

Any input on this would be appreciated

Thanks

Wow! Those were some thin wires, you will probably get a boost from changing those alone. Those 000 resistors are what you want to bridge...technically 000 should be like a bridge, but as we've seen in many of these lights there is often still significant resistance there. Jumper over those either with solder or some thick wire and see if that makes any difference.

The heavier cable seems to have made a difference to it already

I’ll put a jumper over and see what it’s like

Is it worth replacing the wires to the switch or does that not carry current?

Another thing with this clone the switch is very loose even when tightened up fully might have to pack it out or double side tape it down

4

Wires to switch don't carry any current to the LEDs at all, and not hardly any current to begin with.

Also you can put solder braid on the battery - springs, but the biggest boost in brightness will to use good batteries

Switch doesn’t carry current…so those wires are fine

Cover those wires near the emitter with kapton tape to prevent them from shorting to the reflector…they are ALOT thicker than original :smiley:

Thanks for that I’ll leave the switch wires as is

The switch needs sorting though

7

Not sure what kapton tape is I have vinyl tape and self amalgamating tape

The wires are just what I had spare not sure of the gauge they are off a hands free car kit audio loom

8

when you changed the wires… does the reflector is still fit fine? or is the LEDs is sit lower in the reflector now?

The first attempt the wires kept the reflector proud so I had to re-solder them to allow it to sit flush.
