I need to know if it got pwm, but no one seems to be able to answer that question.
Mine, too, has an XP-G in it.
It's PWM, but looks like a very high rate. My year-old Maratac SSAAA looks a little "strobey" on low, and produced massive, thick stripes on low in the camera-phone test. My Cu123 produced thin, hard-to-spot lines on my camera phone, and I couldn't get my hand to go disco - even though "low" is quite a bit lower.
Also, taken alone, the tint looks like a perfect creamy white. In direct comparison, taking the 4500K 92CRI Nichia 219 in my NB/Joule-Thief L2M shining on an ultra-white melamine cabinet as "white": Neutral XM-L Quark-X (which looks yellow on its own) takes on a greenish tinge; Neutral XM-L in the Ti D25C Clicky picks up quite a bit of yellow; pure-white 5000k P4 in the Groovy! picks up a slight tinge of rose, and the XP-G in the Cu123 has the slightest hint of blue. But, on their own, the 219, P4, and XP-G all look pure white to me.It has a significantly more intense hotspot than any of those others, but the profile is very smooth. I didn't have a perfect white background large enough to capture all the spill, but didn't notice any ringiness in the beam.
If you have any desire to own it for the copper, heft, or limited availability - I say go for it. They did a nice job of balancing the compromises in this one. It may not be a perfect light, but it's a very nice one, and pretty affordable for something so unique in the marketplace.
