Nice mod. The extra throw doesn't surprise me, but I figure the lumen output would be similar @ 4A.
And Welcome to BLF, boboweb!
Thanks to all !
The lumens are definitely more ! I can`t measure them but probably they are 30% more.

Let me share some of my experience with my TrustFire ST-80 modification
The original LED was Luminus SST-50. The produced lumens and beam range were OK ! When I learned about the new Cree XM-L LED I decided to try it.
I changed the original LED with this:
http://www.dealextreme.com/p/xm-lt6-885lm-led-emitter-6000k-white-light-bulb-3-0-3-5v-50598
The color tint is very good. I expected to be more bluish. But the light is neutral white. It is under these 6000K maybe about 4500-5000K. It`s very similar to this of the original SST-50 LED. The beam spot is much more concentrated !
The lumens are clearly visible more than before ! The throw is definitely bigger probably 30-40. I used the original 3-mode driver.The current that provides the driver is ~4A@3,45v at the LED. Its efficiency was about 80 with the SST-50 LED and it`s about 90% with the XM-L LED.
I tried and this 5-mode driver:
http://www.dealextreme.com/p/8-4v-sst-50-5-mode-memory-circuit-board-for-flashlights-50025
It gives about 3,85 A. But I prefer the driver with fewer modes.
Between the LED “star” and brass “head” I put Arctic Silver 5 thermal compound for better heat transfer.
Unfortunately I do not have beamshots for now.
Finally I can recommend this modification to everyone who is interested in a cheaper alternative to elite models like TK35,Catapult,M1xm and so on.
The total price is under $90 with the batteries and the charger

Hi, a friend of mine gave me an non working sst-80 flashlight. I believe the emitter is fried. Except the emitter, do you suggest replacing the led too with a t6?
