The Nichia 5000K tint is a bit cooler than I expected. Compared to a few of my other “neutral whites” this feels more on the cooler side. Not a complaint just an observation. Actually when I put them side by side, the Nichia feels the most “neutral” while other “neutrals” feel slightly warmer. I’m starting to like warmer tints so I might have to pick up an XP-G2 5D next.
My only complaint it that the anodization on my 18500 tube is already scratched from inserting and removing the Convoy clip. I guess I can’t expect too much from a $5 tube. Might have to sand down the entire groove to make it look better.
I took D4 for a short walk (buying flashlights is good for health!), have some things to report.
Like said already many times, knurling is missing.
I noticed a quirk in the UI. If I ramp the light up to a fairly high level, wait for thermal management to restrain it an start ramping again, I expect the light to smoothly change output. It jumps to the previously set level and starts ramping from that.
A weird software bug:
Sometimes the light doesn’t notice that I cut off the power. It doesn’t blink on power-on and doesn’t reset mode to 350 mA. Happened twice accidentally, I couldn’t reproduce. Then after playing some I tried to do it again and it happened: there were no blinks. But then I noticed more: now I can reproduce it at will, it happens every time. I think this may be because I have not turned the light on since it happened, there’s some flash state that makes the light not notice and turning it on resets that.
I like the tint.
Very floody, but still less than I was afraid of.
Everybody knows it, but the output is good.
I thought about that. There could be a minor LED temperature improvement by replacing solid trays with vapor chambers. Or actually large portions of head. It could also make powerful lights (D4 counts) slightly shorter. Likely too expensive to be worthwhile.
You could use heat pipes to spread heat over large heatsinks. It could make them more effective, making monster lights a bit brighter.
You could also use something like paraffin wax to increase thermal capacity and thus increase turbo duration.
Ha ha good point! Well i spent $42 with the tracking , think I may be the only one with no 18350/18500 tube though………….for me the 18650 is compact enough and it eats through one of those fast enough
