Easy to Install

This was an easy fix for a 15 year old Surefire. The 2 brightness settings are helpful, as the older model was pretty bright for close work. My disappointment is that for the money, I thought the bright setting would be brighter. Still a big fan, it's a lot of light for a small package.

Very nice feature: two light intensities. Easy fix for a burned-out standard bulb.

Excellent light

Updated older body with this light. Have had another for two years that has great light and is very easy on batteries.

The KX2 dual-output LED head converts single-output incandescent or LED flashlights, such as the L4 Lumamax and all 2-battery Executive series (E-model) flashlights, into long-runtime dual-output LED flashlights. The Total Internal Reflection (TIR) lens produces a tight beam with plenty of reach but enough surround beam to accommodate peripheral vision. The KX2's maximum output is 60 lumens, and its low setting output is 3 lumens, at which it will produce useful light (down to 1 lumen) for 100 hours. Constructed of hard-anodized aerospace-grade aluminum, the rugged KX2 is O-ring sealed to keep out moisture, dust, and dirt. Installs in seconds—simply remove the existing incandescent or LED head and screw on the KX2 head. Available in Black or Olive Drab Green.
