xml2 announced!!!!

please explain, i am confused

If you look at the top of it there aren't any solder pads. This means there is no way to solder it directly to copper (without getting complicated) and still have access to power it up.

I haven’t had time to play with the XML2 yet, but I have a few dozen of them that showed up Friday from mouser… That said, I wouldn’t be surprised if you could solder to the metal under the silicone at the corners/edges…

Has high cri also at the lower colors.

Interesting, it seems like the area to solder wires to may even be bigger!

It does look like that may be the case… It will just depend what material that ‘metal’ is… If, for example, it is aluminum then it will not be possible to solder to it… If it’s plated copper, that would be perfect.

man. it may be time to start practicing my soldering skills. :

Great, I’ll save a little money now, waiting for only lights with an upgraded emitter to come out.

want to see detail

Not sure, but we do have more than a few very capable members for hardware and software development. Perhaps open design (like www.amb.org stuff) where only pcb would be made and sold but users would populate it themselves with readily available parts from RS/farnell/newark/mouser/radioshack…

From what I'm seeing, the buck/boost drivers are more parts, more real estate than the 7135 based designs. This may be fine where you have space in the pill for a 2 PCB design, but won't work on many 1 cell 18650's I've been working on as of late. I'm an independent software devleoper with lots of experience in micros, real-time embedded systems (ASM, C, C++, etc.) and could help with the software though if something can be done - my hardware design experience is near nil though.

Well “standard” 17mm board is quite small and I’m pretty certain that buck/boost driver is not an option but simple buck driver governed by attiny family ic could be feasible. Perhaps even some software code from luxdrv/blfvd could be used.

PilotPTK was in the process of designing a 17mm buck driver which looked fantastic and was supposed to have only a 0.5V overhead - hopefully we’ll hear more after the holidays.

Looks like I’ll be getting some stars and XM-L2s to reflow onto them, can’t wait to try these out in a new bike light. T6 5000K 3C (hopefully) with the same output but better CRI as my current U2 CW equipped light.

I'm still waitin on my Mouser order of 3, shipped Monday, maybe in today. Planning on reflowing onto existing star boards in a couple of my better lights.

Awesome!!! Looking forward to all your results fellas!

Is there a "category" for XML2 on mouser.com? I find their site very unclear..

This is the item page I ordered: mouser XMLBWT-02-0000-000LT60E3. Hope this helps. Down to 142 in stock.

Now if we only knew the exact tint.. :D

He, he, down to 140…

How long until a p60 dropin? :nerd_face:
