Yeah, the only issue is it isn't 2600 lumens. The little asterisk next to the lumen rating says "based on LED manufacturers specifications." Having dealt with the lumens war in the outdoor industry, I can tell you that the manufacturer rating is well above what the LED will actually put out and they don't account for lost light or usable light. It's just how much current can we put through this and what light does it give off before it blows. It's Peak lumens they are quoting.

Now, I"m not saying it isn't going to be bright. It will be. But you'd be lucky to get about 1500 "usable" lumens out of it. Most companies, when stating manufacturer specifications, are not abiding by the below standard of testing. Just food for thought before spending $230 on a light that isn't as bright as it claims to be.

"ANSI/NEMA Standard

In late 2009, with input from more than a dozen manufacturers and other companies involved in the lighting industry, the National Electronic Manufacturers Association (NEMA) published ANSI/NEMA FL 1-2009, Flashlight Basic Performance Standard. ANSI is the American National Standards Institute, a private, nonprofit organization that oversees voluntary consensus product standards in the United States.

The dual goals of the standard:

Create uniform test methods for all portable, single-direction lighting devices.
Present test results in a uniform manner (through the use of common icons), making it easier for consumers to interpret results.
Compliance with the standard is voluntary and, as mentioned earlier, headlamp-makers disagree with majority opinion when it comes to determining run time (preferring to apply the moonlight standard to headlamps). In all other areas, however, headlamp-makers conform to the test methods laid out in the ANSI/NEMA standard."

TK,
thanks for that heads up I was under the impression that a lumen was was a standard not bragging right as you say.

The article on the mod does show pictures of the light in the dark and the " Light fall" image also if 2600 is not enough they do a 3800 version.

LED specs are ridiculous... no consistency whatsoever.

There is a lot of misconception out there as well. I have people tell me that the good thing about LEDs is that they don't generate heat....ha! Maybe not the little 15ma LEDs they have on their keychains, but real LEDs get extremely hot.

Darrin,
yeh not exactly cool lights for sure, the heatsink on my big hand held gets so hot as to warm the hand grip area and that is some kind of tactile rubber compound made to stay firm if hands are very sweaty, covered in oil,water blood etc.I just hope it is flame proof :-}
