Even with a fresh-off-the-charger cell, moon is still too low to register on my light box. It’s about the same as the “0.06 lm” mode on a Zebralight SC52, which is actually about 0.01 lm according to selfbuilt. (If I use my other lumen-measuring tool, mine also says 0.01.)
So, it’s bright enough to count as a “firefly” mode or locator glow, but not bright enough to really see anything more than a few inches away. I’ve had GitD tail caps brighter than this.
Anyway, when I’m all done measuring I’ll see what I can do to fix it and get it into the desired 0.20 to 0.50 lumen range.
As for the other modes, what I’m seeing is (with a full 25R cell, at 4.18V, at start instead of 30 seconds) is:
Mode group 1:
1: 0.01 lm (should be ~0.30 lm)
2: 7.95 lm
3: 58.6 lm
4: 184 lm
5: 429 lm
6: 803 lm
7: 1379 lm
Mode group 2:
1: 7.95 lm
2: 121 lm
3: 533 lm
4: 1379 lm
This was an unmodded light using a Samsung 25R cell, so it should be brighter with spring bypasses and a hotter battery.
I also tried earlier with the cell at about 3.85V (about ~60% charged) and got 1100 lumens. The highest mode will decline with voltage, but it should stay over 1000 lumens for quite a bit of its life. If you want an idea how it behaves in unfavorable circumstances, I tried a weak cell with much of its charge already depleted — 816 lumens from an old Panasonic 3100mAh low-amperage protected cell at 3.65V. So even limping along with a low charge on a weak battery, it’s still about on par with a car headlight.
I’m not a fan of moon mode but the range of modes is enough to satisfy everyone. I’m most interested in the high modes. This is clearly going to be a pocket rocket. Possibly the best GB so far. great work guys
ssshhhh! Or the moon’s mode mafia will kick your a**s
O,02 lm Omg!!
I’ve a Maglite “Solitaire” (1xAAA/not led), and it’s claims 2 lumens…very very very low power, but in a dark room is enough to see if the children are sleeping. 2 Lumens…I really don’t know what will be a 0,5 lm firefly mode. I’m very curious, really :bigsmile:
After spring bypasses and using hottest battery on the market will I be able to actually spot the difference in output with my eyes compared to the “standard” 1379 lm?
Not really. Even compared to a standard 700lm XM-L light we already had three years ago it does not look that much brighter.
(but that is not the point for a flashaholic :bigsmile: : it is brighter than we had before, therefore it is desirable, and the excellent UI plus efficient low modes makes it exceptional)
