I’ve just managed 29,000 lumens @ turn on against my X80 that measured 23,000 lumens.

so yeah not really 32k lumens even if its close its not…. U were right JasonWW lol…

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.

Thread closed until tempers cool.

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.

LMFAO @ you people that can’t find the hole. Seriously.

I would hate to see any of you try to clear a weapon malfunction if you can’t even find a button.

IT LITERALLY TAKES LESS THAN A SECOND

Eyes closed. Grab it. Finger opposite thumb. Rotate the light. Wow what’s that?

Oh.

The button.

Wow.

I don’t know about the DX80, but if you keep the handle on the X80-GT it’s comically easy. The button is opposite the handle.

I grab it like this: Holding X80-GT - Album on Imgur and then once I get it to the setting I want, I hold it by the handle.

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.

I’ve made a new integrating sphere and turn on wise I get this:

MF01 9500
DX80 13200
X45 15800
X80 24000
X80-GT 36000

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 finally got a chance to play with this light. I am pretty happy with it.

Do you think it would perform any better if it had unprotected cells?

The_Flashaholic · 2018-08-17T15:41:30.000Z

Another Imalent hater, I never mentioned my Acebeam X80 was faulty on my DX80 review.

Glad you matched my ceiling bounce figure dead on.

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?

It’s not direct drive, but other driver types can still benefit from a reduction in internal resistance.

Who knows, it might produce a few thousand more lumens.

I’m guessing it only takes button tops? I guess you could always solder blob flat tops as well.

Some of the best high drain include the Samsung 30Q and Sony VTC6.

What voltage is that, 6V or 12v?

The_Flashaholic · 2018-08-17T17:43:50.000Z

I have 30Q’s, VTC5A and VTC6, I can try them later.

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_Flashaholic · 2018-08-17T18:15:10.000Z

I’ll try my protected 18650 Imalent batteries too!

I’m pretty sure those are 30Q under the wrapper. In case anyone was wondering.

Oh yeah, I think they are just 15A. So they might trip the protection circuitry.

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.

The_Flashaholic · 2018-08-17T20:17:12.000Z

With a cooling period between tests I got the exact same lumen reading with the Acebeam batteries, VTC5A and Imalent batteries.

My VTC6 flat tops were too short.

They’re not charged yet but there’s no point in trying 30Q.

For my reading sphere I got my hand in with the tiny Olight S1R and pointed it in every direction to eliminate flat spots. It really is accurate.
