I didn’t notice this was posted yet, sorry if it was already.
Looks like some of you were right, manufacturers keep raising the bar with these multi-Led lights. Now we have a 15x XML on the block. I’m sure the output will disappoint as some of the previous versions, but looking down the business end of this one is sure cool.
It also boasts 3 different types of cells which is something new, 4*18650/4*26650( 4*16650 Best )
Lol, nice find
this will definitely be bad for such a heavy beast in stock condition…I guess 5A max…what will cause serious heat anyway…
But hey 4 cells with 5A are still more light than the most of you have…and 26650s for high current are hard to get
I guess the driver will be one of the crappy ones which are in the 12 or 9 XML lights, with one difference it will be no direct drive over a FET (like in 9T6 or12T6 woth 3s3p leds)because for that you will need a number of LEDs which you can divide through the number of cells…
so I am waiting for the 16XML which is capable of 12 18650s, that would be my dream light: giant KING! >)
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
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.
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.
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.
