Very new to modding - what can i do to pump up the power in one of these puppies?

Hey guys, i’ve read this forum for a while now and bought a few flashlights, but i’m curious about modding, since i’d like to see some huge volume of light in my hands Smile

I have a Skyray King (1 led died when the light was “on” for hours inside my backpak) and a new 4*xml2 light (http://budgetlightforum.com/node/31316 this one in fact).

The skyray has this thing for a driver. From what i can collect it’s a little piece of crap.

The quad light has this thing.
Honestly i’m quite disappointed in the new one, because the brightness is pretty much the same as the skyray with 2 functional leds.

What would be the simplest way to boost the output in one of these?
I read things about resistor mods, but i haven’t quite collected enough to know how i should go about it.
Another thing i read was wire thickness – how much of an impact does this have?

Thanks!

On the second driver, can you tell us the value of R1?

The second driver looks to have a bank of R270 resistors, (.27 ohm). These I would guess to be the limiting resistors. try bridging one of them, and see what happens.

As extra credit, go take a look at what RMM is offering in terms of SRK’s and M6’s. That might give you some ideas.

If you can’t blind them with your brilliance, baffle them with your bullcrap.

The real currency in the world is not money, it’s trust.

R1 seems to have 102 written on it.

There are indeed 3 R270 resistors.

Thanks, i’ll see what i can do with these for now.

The stock wires on the quad look pretty beefy. Looks like they cut the insulation fairly high up on 1 of the wires in each of the red/black bundles. Might want to wrap that puppy with electrical/Kapton tape to prevent a short.

Apart from that +1 to what musicmagic said.

If the driver happens to crap out on you then there’s a ton of driver options from Direct Drive to 7135 chip SRK drivers with customized UI’s you can get for it.

Haven't seen either of those drivers before.  Kind of weird that Quad.  Beefy ground ring and wires, but the components look wimpy.  The SRK driver is the other way around.  I would be tempted to replace the FET on that SRK driver with a 70N02 FET and then pull that modes chip and air wire an Attiny13a MCU.

Before you crank them up, check and make sure there is actually a shelf under the LED plate/MCPCB serving as a thermal path.  I've been seeing more and more of these lights coming without them, with the MCPCB just screwed into the reflector...basically floating in the air! Yell
