Light emitting diode (LED) technology is now available as an add-on conversion for SureFire's Executive Series of high-performance flashlights. The conversion head consists of a bezel/lamp assembly fitted with a digital regulator, a three-watt LumaMax LED, and a custom designed light-focusing lens. The primary benefit of the LED Conversion Heads over a standard incandescent lamp is runtime. LEDs produce light more efficiently at low wattage levels, so a battery that is too depleted to run an incandescent lamp still has plenty of life to power an LED. The drawback to most LEDs is that they do not produce a steady amount of light as the battery drains. However, SureFire's LED Conversion Heads differ from other manufacturer's LED flashlights by using a digital regulator (KL1 & KL3) to maintain a consistent level of light output for as long as possible, while also protecting the LED module from current and heat-related damage. SureFire is the first to utilize these breakthrough features in a hand-held LED.

Fits all Executive Series flashlights:
E1/E1EOutput/Runtime: Max 25 lumens output and 4 hours runtime (1 hours high output, then 3 hours of useful output).
E2/E2E Output/Runtime: Max 30 lumens output and 6 hours runtime (3 hours high output, then 3 hours of useful output)

• Construction - CNC machined aerospace-grade aluminum. MilSpec Type III super-hard anodizing for corrosion and wear-resistance, light-focusing lens window
  
• Digital regulator circuitry ensures consistent light output for maximum duration, light output does not "drop off" like an unregulated LED
• Shock-proof Luxeon Star LED rated for thousands of hours of usage
• White for maximum brightness, high color temperature, and true-to-life colors
• No Hassle Lifetime Guarantee: If it breaks, we fix it!
