    What's the "go to" LED and optic these days?

    Been a while since I put together a light, but my work has a nice new (old) bridgeport mill and a kinda crappy but functional manual metal lathe, and I need a project to get back up to speed on using both, so what better than making a couple lights?

    Looks like the new hotness is the XP-G2 and/or XM-L2. I'm primarily looking for a bar light (a bit floodier), a helmet light might come later.

    I was thinking of either a 2x xm-l2 or a 3-up xp-g2 for the bars. Or heck, maybe a 2x 3-up xp-g2! Are Ledil Cute optics still the go-to for 3-ups?

    Cheers!

    XM-L2 is a very popular emitter. 20mm TIR optics from LEDDNA are pretty good with it, particularly if a wider beam is your preference. It's a pretty large die so if you are looking for throw, you will need to go up to a 35-40+mm reflector.

    Ledil Cutes work kinda good for a 3 up though a pretty wide beam even in the narrow version. I've got a 2X 3up XPG light with the narrow Cute on it. I lap sanded the diffusion bumps off the front and polished it back out to get a bit more focus and throw. It's fine on the bars mainly because it just puts out a lot of light.

    Is there a difference in emmitter size between an XM-L and an XM-L2? In other words if I am happy with my XM-L optics will I be just as happy with the same optics on an XM-L2?

    Is the XHP any good is it going to be another pointless exercise like most of our mc-e lights where?


    TIA

    ps, I have been away from here for far too long and things are getting really complicated with people designing / building their own multi channel drivers etc

    Emitter size is the same XM-L and an XM-L2, so the optics should give essentially the same performance. I haven't bothered upgrading, but in addition to the 20% more output, it seems that the XM-L2 will run at higher amps - up to 6A by some reports.
