LOVE IT!!!!!!!!!!

I've had two G2 Surefire flash104lights for a number of years now. One I use for work several times a day. Best flashlight I have ever owned. However with the new LED conversion bulb, it now surpasses the past performance. I do not know what I would do with out it.

Thank you so much for a great product!

Upgrade for my C2 centurion

The lamp went out on my P 60 head so in looking to replace it, I found the KX4. Big difference in power and battery life. Like a whole new flashlight. Great product. Thanks to surefire for not making me buy a whole new one as the C2 is a great body for my rifle.

KX4 LED conversion

I have been a Sure Fire user since way back. Several years ago Sure Fire had a LED conversion for 6P and Nitrolon that I used. It (the previous model) had a tighter beam and not as much spill-over to the side of the beam.

The new KX4 has a very bright beam and out about 30 feet it seems like a flood pattern not a spot. In fog and smoke this scatter is very annoying and makes it hard to see at distance.

I do like the fact that my red & blue filters will fit the KX4 where that didn't fit the previous model LED head.

Thanks Sure Fire for making a bullet proof LED for the Nitrolon lights. If you ever make a tighter beam pattern for these lights I will upgrade.

Very bright light and a significant improvement over the P60 bulb. Seems to be overpriced for long time customers but otherwise great.

Works really great, However it is really over priced. I the original light only costs $59.00 dollars then the new light is $99.00 dolars when all is said and done! if there is a next time that this light goes out I will not replace it with another bulb! I will buy a different light that is lower cost.

Surefire flashlights and KX4 LED

When you need one, nothing beats a good flashlight. I bought my first Surefire flashlights with incandescent bulbs, but when I tried out the LED, I was sold immediately, and I replaced my incandescent bulbs with LED. The light is very white and intense, and when tested against an incandescent bulb there is no comparison.

I wish I could tel you how long an LED lasts, but I haven't burned one out yet.

The company Surefire is very professional and delivers what they promise. I have never had a problem.
