LED Replacement Heads
Gents:
Recently acquired a Surefire KL3 One Watt LED Module replacement lamp (Thanks Air .177!)
This is Surefire's LED replacement head for the 1" diameter lights, 6v. and 9v.
Initial observation is that it is expensive (around $50) and big (almost 1.5" in diameter and 2.2" long, compared to the standard 1.2"x1.3" Surefire incandescent bezels).
Installation takes less than 30 seconds.
The KL3 Module on the 6v. body makes almost 20 lumens for five hours, then runs an increasingly dimmer light for another five. On the 9v. bodies, the KL3 puts out the same 19.5 lumens for more than seven hours before dimming to the end at 15 hours. The output is a little less than 1/2 the lumens of the standard lamps (55 lumens), but the lights burn more than four times longer, and are usable long after the batteries will no longer power an incandescent lamp. The beam is also wider and more uniform with the KL3 than the standard incandescent lamp, which tends to have a very "hot" center and dimmer halo.
This is a 6v. body with the KL3.

The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat." - President Theodore Roosevelt, 1910
