A few pics of what may become my next bar light housing. It will hold 6 XPGs on 10mm stars using the Cute SS 35mm triple optic. Planning to use an H6Flex. Looked OK on paper but after starting cutting it, I'm not sure everything will fit.

6 XP-Gs should be enough :) Why not XM-L though, then you'd be able to use the EVA 35mm reflector?

where's the driver going, at the back? Kind of hard to tell from the pictures..

XPGs because I already have them and the optics. They also work better with an existing 14.4V battery setup I have.

Driver is planned to go into a slot cut in the bottom, behind the LED cavity. I only have the outside shape milled in these pics. I'll start on the LED cavity next.

ah, gotya, figured it might have been something along those lines. If you have them, you might as well use them!

out of curiosity, why is the shape at the back the way it is?

looking forward to the rest of it - less chat, more machining :)

The back is shaped to kind of mirror the shape that the triple optics and LED cavity will be. This is my first attempt at using a CAD/CAM software to generate the CNC program for a shape.

More machining it is! A start on the LED/optic cavity. The pic is from my phone, so not too good.

Project revived

Finally got my lazy a$$ back on building. Led cavity is finished and the optics cut and glued together. Change of direction from my original plan. Still going to be 6 XPGs but I am going to run them 2S3P with an Lflex and a 7.2V battery. I know there are possibly issues with parallel strings, but I'll try it. I have done a couple lights with series MCEs in parallel and they have been fine. It will have a remote switch like my current MCE bar light. I'm making a few extra switch housings in case anyone has an interest. They will be similar to the one in this thread....

except made of black Delrin.

Tried to do some more work on the light and remote switch housings today, but the DRO on my mill wouldn't turn on. Looks like some trouble with a voltage regulator. Supposed to have 5V out of one board but only getting 3.8V. I'll have to do a bit of looking for parts Monday.

Nice to see that this light is finally going to come alive.
you have given an idea!
Could you recommend a glue for gluing optics together please.

good luck with your build

Very cool looking light!

Since you are into super minimalist designs, I'll ask here and hopefully not threadjack. A while back, Troutie posted a pic of a triple XPG that mounted on the front of his bars. It was barely even there. I PM'd him about whether it worked or not, but haven't heard back. Any of you try that? Seems like you could run a couple of L334's, maybe one throw one flood and use the bars and body as heatsink and just run a y cable to them through a switch.

I just used some model cement because it is clear and has a fairly thick consistency. The optics are made of a type of acrylic. Acrylic is a very easy plastic to glue. Don't use superglue as it "clouds" the optics usually

I have carbon bars so have never built anything that would use them for heatsinking. That has been done, to the best of my memory, by others.

When Quazzle's module was announced I planned a tiny build for a helmet light with one. I dropped the idea after discovering the Carclo 20mm triple optic's beam shape is not to my liking. I love the idea of minimal builds, but not at the sacrifice of a beam I like.

How bad is the beam with a narrow clear? That's what I have - and a narrow frosted.
I don't want to say it's a bad beam, it just is too much flood and not much throw with XPGs for my preference. I don't like having much light spread out to the sides. I find the shadows that creates to be an eye catching distraction. Offroadbent says the throw is good with XPEs.

My gut feeling is that the light in this thread will have more flood than I want. If it does, it will be easy to find a new home for it and build something else.

Why not build it with XPE from the start? Plenty of LED's and the XPE, from the pictures that I've seen, really does have a smaller beam.
