As requested, 3 XM-L Driver/Emitter module DIY

Ok, are the production version ready to ship just yet or are only the prototype boards finished so far?

Sorry I missed the price on the first page, maybe try getting that into the Original Post?

Sorry if this was discussed, but how hard or easy is this: “Max output: 3.2Amps (up to 5Amps with one resistor change)”? Would you change the resistor if we request?

I do have production versions ready, but I haven’t done a ‘big’ run of them (which is why I haven’t really advertised them as available very heavily). The reason is that I’m still waiting on the U2 Emitters that I ordered, and I want to run a big batch of Cool U2, Cool T6 and Neutral T5 all at once since more of the production cost is setup time than actual run time.

If you’re interested in a Neutral T5 or Cool T6, I have a few available.

Yes, I’ll be happy to make the change - although I don’t necessarily recommend it. 5 Amps * 3 Emitters gives about 52.5 Watts of heat. You had better be putting this module in an enclosure made of about 5 pounds of copper if you hope to control that kind of heat.

If you’re only going to use it for a short “Turbo Mode”, it will be fine. But, don’t plan on long run times, unless, like I say, you have one heck of an enclosure/host.

Why do you want or need 5A? It will produce far too much heat, you will need forced cooling unless its mounted to a HUGE heat sink.
The hotter an LED gets, the less lumens they give out. So running hot at 5A may produce the same output as seen at 3A, with the bonus of a smaller housing. Also, look at www.budgetlightforum.com/node/2603 , a sticky in this section of the forum.
You can see the output tails off after 4.4A... Now look at the size of his heatsink, and he's only got one LED...
Your eyes won't even notice the extra 10% in output. Why not try 4 XMLs run at 3A? You'd get more light and they will be a whole lot more efficient.
Or two triple boards run at 2A. You'd get about 4100 lm at 36W. One triple run at 5A gives out about 2900 lm at 45W.
I don't know what your set up is and I'm definitely not trying to knock you down, just though I'd put some info down for ya. I've made some silly lights and run them at huge currents only to find more LEDs at a lower current is brighter and kinder on my batteries!

Alright, so I put together a plan for a Maglite host.

–2D Mag
Custom milled bezel (replaces the stock head and threads on to hold the module in place, like the one shown here 3D Magmule with triple Nichia 219s)
-Custom heatsink that rests on top of the switch housing and rises just outside the mag body for the module to mount to
–3 x 26500 IMR cells

Cost to put all of this together will be around $160. Way more expensive than I wanted, but it will be a nice light :slight_smile:

Did PCC agree to make you one?

Still talking to him about it, nothing set yet.

I can’t believe I just noticed this thread. What an awesome job you’ve done. The closest I’ve seen is the 4x xpg from Eltehs in Lithuania and they haven’t answered any emails. This is a big upgrade in the market. By the way, thank you for taking the time to help along non-engineer hobbyists like me.

PPtk,

I wanted to once again thank you for the advice/tips on the test points. I ordered a few to play with, and I found them even useful for testing LED’s as well:

You were right, these totally rock - thanks dude!

The heatsink’s been made. Working on the bezel now.

The screw in the middle is for the mounting. I still need to drill the holes for the wires.

Oh, yeah, PilotPTK, had you made the circuit board 34mm in diameter instead of 35mm these would be able to fit inside of a D-Mag with the optic hanging off the end of it. As it is the Mag would have to be bored out or the board modified.

Would you like to make a second PCC?

The heatsink part of it can be easily done. The bezel is not. I’ll need to buy some more 1.625” round stock before I can make more. Actually, I’ll need to buy more 1.375” round stock if I want to make more D-Mag heatsinks as the one I made for JohnnyC was almost the last of it. I have enough material to make just one more at this point.

Kick ass! Looking good PCC! Is there threading for that screw? I was just planning on running a bolt through with a nut on the back side.

It’s tapped M3 and you’re getting the screw that’s in the picture.

Peter is on the home stretch with the bezel, I can’t wait to see it finished! :slight_smile:

I just need to decide on a UI and LED bin. I’m going to convert the mag switch to be momentary ground, with the positive bypassing the switch entirely to power the module with only the tail cap lockout to cut the power. This way I’ll be able to have 3 standard modes, then a long-press to access hidden modes. I think I might do the ramping option for mode switching as well (ramps up or down to the next mode) - it would be something unique at least.

As for the bin, should I go all out with the U2, or go with the T5 to get a little better color rendition? Hmm…I can’t decide.

Are any projects utilizing this module completed yet? Surprised this thread has died down.

There was my project but it failed because of the height difference between this module and the maglite head. I ordered a heatsink and bezel from PCC too and will be installing it in that.

I had to redo the bezel because the first one I had made was made too short by about 1/8”. Here’s the parts I’m about to ship off to JonnyC. I’ll need to make one more lens (spare) for him.

Hey PCC,

Have you made any progress on mine?
