K9 LED conversion on M3 Combatlight

I converted my older halogen light with this unit. Output is far greater. I wish it had a strike bezel, but other than that I am totally happy. Surefire is expensive but provides commensurate quality and performance.

KX9 Led Conversion for M900A Battle Light

I have been waiting for this conversion for a long time and though it is pricy, I'm very happy with the two I have recently converted. As stated in other reviews this conversion was very simple to install and it works like a charm.

The output is very bright which makes for a great defense light as well as a hunting light. I have not taken it to the field as yet but around the ranch it really impressive. Can't beat SureFire, in my opinion, they are easy to deal with if something breaks even if it is not a productive.

This is a nice conversion and extremely easy to install, requiring a mere screw in and go mentality. However, be on the lookout for erroneous manufacture of this product. By this I mean that when you run filamented light bulbs, the polarity of the batteries does not matter. Therefore the batteries can be place either negative up or positive up and the light will work. However, LEDs are polarity sensitive. My fore-grip light came with two small entry illumination LEDs. That means that my polarity must be correct with negative up polarity with my 3 CR123 batteries. The good folks at Surefire made a mistake in manufacture as the polarity of my KX9 was reverse of my entry LEDs. I have an electronic background so I took the unit apart and soldered the wires to the entry LEDs reversing their polarity so they would work with the KX9. Surefire would have warranted this problem but I did not want to send it in and wait. Most people should check this immediately and send the entire unit into Surefire if you find that you must reverse the batteries to get the KX9 working as you will lose your entry lights.On the positive side, I was running the brightest xenon bulb that was available and the KX9 is so many times brighter that I decided to put it on my .308 as it will give you long range lighting. I wish they made an infra-red lens cover for this but not yet as this light would really light up all generations of night vision. All in all, nice bright light once I got past the OOPS from Surefire.

The KX9 LED head converts certain SureFire 9-volt incandescent flashlights and WeaponLights (models listed below) into single-output LED illumination tools that generate 800 lumens of blinding white light. The single-output KX9 features a Total Internal Reflection (TIR) lens that produces a tight beam with plenty of reach but enough surround beam to accommodate peripheral vision. Because this type of beam may be desired over an extended-reach beam for some applications, the KX9 can also be used on certain nine-volt LED flashlights and WeaponLights featuring Turbohead TIR lenses (models listed below) to create a single-output beam with increased peripheral lighting for better situational awareness. In addition, the KX9 can be used to convert dual-spectrum M500V and M900V LED WeaponLights into higher-output, white-light-only systems. Constructed of hard-anodized aerospace aluminum, the rugged KX9 is O-ring sealed to keep out moisture, dust, and dirt. It installs in seconds—simply remove the existing incandescent or LED head and screw on the KX9 head. Currently available only in Black.
