Don’t show this light to people with trypophobia.

I guess this is where all the leftover 1st gen XMLs went.

The TF AK90 has a similar sized head, with 12x XM-L. This 15x light has less heatsinking mass/area than the AK90. I doubt it could handle any serious drive current for long.
Still, anyone willing to take one for the team, it would be nice to find out more about it :smiley:

Let’s do some math… 15,000 lumens would require more than 150 watts. Divided by 4 batteries gives over 40 watts per battery (with driver losses). Batteries at 4V would be over 10 amps per battery. Yeah, like that’s gonna happen.

And I know how much passive heatsinking it takes to handle 150 watts (15,000 Lumen Bridgelux C9000 Light Engine) That thing would be molten slag in moments…

hehe, reminds me of a guy who cooked breakfast over a campfire in an aluminum frying pan. The pan go so hot it melted without warning (aluminum doesn’t glow red before it melts). I don’t think I laughed quite as hard, before or since.
I agree pyro, even the AK90 is going to be a three minute turbo at 100W or so. It takes a lot of surface area to dissipate that much heat passively.

14

And the batteries are empty after 15 minutes…

15

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

16

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.

19

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

20

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

21

looking forward to your review on this 15 emitter.

22

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!

26

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:

27

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...

28

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.
