Keep in mind the current requirements for 60k lumen. 4 x 18650 will not do it. That is the limitation. I’m skeptical the X80 GT can do 32k lumen. Especially if it uses 4 of Acebeams 15A protected 18650.
That post was by KG_Tuning. If you read this thread, his recent posts about lumen measurements caused a bit of commotion. I wouldn’t fully rely on his measurements until he gets a Maukka calibration light.
I measured 22,300 lumens using the Texas_Ace calibrating tube for the X80-GT.
For reference my X45 managed 10,100 and DX80 20,000 (I binned the garbage)
I suspect Maukka will get closer to my turn on reading of 29,000. Maybe a tad more in fact as he usually hits a little higher than me.
If your hands are too small to hold it that way, keep the handle on it and scoop it up with your thumb like this: Holding the X80-GT part 2 - Album on Imgur and your finger naturally rests on the button.
EDIT: I now have it down to 33,000 @ turn on after blocking a little spill from hitting directly over the sensor, the other lights remain the same as their flood wasn’t so wide.
I’m not sure if its a direct drive or not. I measured about 18.6 amps at the tail with those (forgot to add that clip to the vid). I suppose I should probly own a set of 4 matching unprotecteds. What’s the best thing going in low resistance high discharge these days?
Its the 12v config. I tested while the pack was fully charged, but even if we assume 3.7V per cell under load were looking at over 275 watts. Pretty impressive I though.
Yeah, most companies making a 30,000 lumen light would use 8 x 18650 (Astrolux MF03, Imalent DX80). Only 4 cells is impressive (for 25 seconds, at least. )
What impresses me more is that those cells must have 20A protection circuits. I’ve never seen them that high. I’ve seen a few cells using 15A circuits, but that’s it for 18650’s.
Yep, the Acebeam site shows they have a 20A circuit. Really expensive suckers as well.
I always measure higher lumens with the Sony VTC5D vs the VTC6. You lose aoubt 200-300mah with the VTC5D though but it still has more capacity than the VTC5A.
The VTC5D doesn’t appear to be in HKJ’s comparator. I wish it was.
This is a fairly new cell I believe. I think it was made for the Dyson vacuum company, hence the D suffix.
Mooch has done a comparison here.
Honestly, I get a lot of these Sony batteries mixed up due to their name. That’s why I tend to stick to the 30Q. It has both good power and capacity and the name is easy to remember. Lol.
