Too bad I can’t try out my aspire batteries, I think there’s something wrong with my 18350 tube, the light works great with the 18650 and 18500 tube…any suggestions ??
Is that a hidden feature? It’s in the UI diagram, and Hank found it important enough to add some text about it to his version of the diagram. Here’s the image shown at Intl-Outdoor’s product page for the D4:
Ran a thermal runtime test on the D1 with a 30Q. It held turbo for about 1:24 sec. Gradually stepped down all the way to about the 10 minute mark. At that point I think it was about as bright as the regulated to FET jump point. Then held it until around the 12 minute mark when it started to ramp up again. Love it! After 15 minutes it was warm to the touch and the 30Q was at 4.10V.
Also, not in the video but I compared it to one of my worklights, a Streamlight Stinger LED HP 350lm 56kcd, and the D1 seems to throw a little farther with a significantly wider hotspot.
Yes, it is real nice for evening /night uses(reason I say that, if used in the day in poor artificial light, it can do all kinds of things to 4000k beams. 5000k works better for me in these conditions). I have an EDC plus triple, that is also xp-g2 4000k and why I new I would love the D4 4000k. Also Malkoff uses the 4000k xpg2 for his N (neutral).
