LightMalls UltraFire 15T6 16000-Lumen 15xCree XM-L

And the batteries are empty after 15 minutes…

15 XM-Ls, wait for the 20, should come soon.

This is insane ! A bunch of XML ! I really hope someone will do a review about it.
Also can be used as a mace.

Hey there BLF peeps. I just created an account because I happened upon this thread while researching the light you all are talking about. I ordered the UltraFire 15T6 (along with 4 other beasts) from lightmalls 2 days ago. I wanted to let you all know that I’ll post a review when I receive it.

By the way, clearly I love torches (well I’m here, ha), but frankly I’ve never modded a light or soldered an LED. I’m just learning & plan on upgrading some lights & playing around with the ones on the way.

Cheers,
Zeke

Hi Zeke,

Welcome to the forum and congratulations on getting what we all hope to be a great 15x XM-L light. I’m sure we all can’t wait to hear your impressions of this big beast. Please keep us posted.

Welcome to the family, Zeke! Looking forward to your impressions of this light. What are the others you purchased?

I always wondered about these shower head multi-emitter beasts please post your findings and enjoyyour stay

looking forward to your review on this 15 emitter.

I hope you have ordered some good batteries too. And you will definitely need big leads for your multimeter to measure current…

Nice! I bet that box is going to make you happy for a long while! Beamshots of x100 vs 15xT6 ASAP please!

I bet the “North Texas” will be a no-fly zone untill after you have finished your tests. :bigsmile: And if you want to just keep some of them and discard the others, there will be people considering those treasures. :heart_eyes:

Hey Zeke! Any first impressions? Tail cap measurements? You do have or have access to a DMM I hope?

We're all waiting to hear about that monster.

Oh, ah... Welcome to the forum too...

This seems cool, but not too useful for reasons some of you already pointed out.

Another reason is that the human eyes perception of light is logarithmic analog. It is not linear, in other words. So you double the lumens, diminish batts life, but get only a slight brightness increase in perception.

To date, I think the 7 LED flashlight is the most useful, striking a good balance of perceived lumen and battery life.

More results in diminishing return.

Even if you are right (did not check), you are comparing the light at the same distance and area. If you get more throw and wider flood with the extra light then it is good for something. If you do not need see that farther, use the med or low mode to get more battery time. My 2 cents.

There’s definition some uses for it, but not much.

Plenty of reference about the eye perception of brightness. Here’s one

The reason I got into that research was because I mod a 7x and a 9x. Data showed more lights, more current consumed. But my eye said, “yeah, kind of.”

But, it is fun!

Well, what I notice between my J18 and 12xT6 on hikes is a perception that the “entire forest” around me is lit up, wider flood + brighter. Yeah, it cant keep it up too long, but its significant. 15xT6 should be even more significant! Sometimes I do like going with just a J18 though, because of the longer runtime and more level output over time. I’m tending towards running the lights on lower settings, but interestingly enough, the 12Tx6 is still preferrable, just by the fact of the bigger flood zone. I switch all the time between J18/12xT6 and on short hikes I alternate in SRK/Kung/C8 along with the big ones, all my lights are fun, depends on the mood, distance, other people with me and location :slight_smile:

The J18 is insane though with the IOS driver, and KK cells - 5,500 lumens I measured... DayLighter has it now, but I got a J18 and the IOS driver, waiting...

Which driver is that Tom E? I have a J18 on the way.
