McGizmo LS20 XP-G Update

[tx101]

I send him an email a while ago asking about the same mod your after Stoli, no reply

[stoli67]

It doesn't look good ... He does some crazy mods ... Really would like the XPG / XML combo mod but I could live with just a really nice neutral XPG centrally...

What would be good would be a neutral XPG and a mule nichia high cri !

[tx101]

I would try an emitter swap out myself but am concerned about getting a XPG

focussed correctly with a LS20 reflector.

Which MCPCB would work best, the standard Cutter 10mm board or a Shoppe 6mm XPE board ?

Ideally I would like to swap the 3mm emitters out for some neutral ones ... can anyone point

me in the right direction ?

Hey guys! I appologize for not getting back with you. My internet is horrible! Most times I try to respond to a forum thread or respond to an email it either drops out or won't let me edit. Anyway it drives me NUTS so I just stopped going online as much and then got busy with work.

I'll be taking modification requests again starting next week.

The last several months have been spent working whenever and wherever possible followed by working in my shop to be set up more efficiently. All my machine tools were striped down, cleaned, painted, relubed and reassembled. I purchased a 9X18 lathe that ended up being a huge PITA...JUST got that running again. I spent the money I had saved for a car on a PM1127VF-LB lathe. That will be delivered monday or tuesday. Also got my milling machine running again.

As for the LS20 mods....the latest one to go out had my new heatsink design that increases mass and contact with the wall on the inside of the head helping to dissipate heat MUCH better.

The LS20.1, using the xp-g with an McR10 and an XM-L for the flood is also an option.

I'll be busy for the next week working on a few cars and setting up the new lathe. After that, I plan to be able to offer modding services again.

tx101, did you get my email? never heard back from ya.

Here's an update on what I've been working on.
The original LS20.1 heatsinks were aluminum and a pretty basic design that added a lot more mass than the stock heatsink and also more contact area to the head to improve heat transfer.
After much thought and a redesign, a new improved version was made from brass.

It's a huge step in the right direction for thermal management when running a HO GDuP driver to the emitters.
The brass slug is "stepped" in 3 places and has a tight fit to further help transfer that heat to the head. After turning the slug to its final size, it's seated in a special holder I made for the milling maching to have the holes drilled and pockets milled for the emitters and wires. Another holder was made to secure the brass finish rings so they can have their holes milled and the backside milled for wire clearance for the XM-L.
I feel much better about the new design even though it takes WAY more time to make than the simple design I previously used in my personal light.
About the only improvement I can see from here on out is a way to heatsink the drivers and make the drive assembly
and LED heatsink plug into each other for ease of assembly/disassembly.

Anyway, heres a few pics.

Well since my stupid cursor won't go where I want it to to edit my post I have to follow up! F-in computer pisses me off to no end!
Anyway, you can see the original LS20 heatsink on the right end followed by the new brass heatsink and finally the original LS20.1 heatsink on the left end.

That is an awesome design. Very impressive work. I hope that dual emitter set-up makes it into more than just the LS20.

You use a GDuP driver in a PD light? How does that work? My mod just adds extra modes to the spotlight, but not to the floodlight. Have you figured out a way to do both?

Thank you. It's just for the LS20 at the moment.

frystormer, the GDuP is for the reflectored emitter....the XM-L is driven off the original driver for the 3mm LED's. So nothing different there...just the improved heatsink.

No, I never received any reply ..... most probably, your email is lost somewhere on the net.

Still interested in getting my LS20 modded

Looking forward to updating your light! Keep me updated on what you want to do!

Heres an updated pic of Obi's LS20.1B
Had a chance to use it in a dark wooded area and was completely impressed by the output of the XP-G powered by a GDuP on high!
The large contact/surface area really does its job of transfering the heat to the head!
So far I'm completely happy with this new heatsink design of the simple aluminum proof of concept design.

[easilyled]

Wow, that looks superb. How much current is going to the XM-L and the XP-G and how does the UI work?
I presume that you mod users' existing LS20s and that you don't have any complete modded LS20s that you would consider selling?

Ah, so it's essentially the same as the Centauri mod, but with newer emitters installed as well.

Perhaps Don can correct me if I'm wrong, but I think the flood driver outputs around 11V to support three LEDs wired in-series, with a ~3.6V voltage drop across each one. How does that work with the XM-L emitter?

sooner or later I need to get a lunasol 20 and have this done to it. wow nice job.

Question, could you make this set up in a p60 package? I think it would be awesome.... Et me know, I would be own or e if not two.....
