Surefire L4 LumaMax

The L4 is the brightest led flashlight from Surefire's E-Series. The body, tailcap and bezel are compatible with parts from the E1L, E2L, E1E and E2E flashlights.

The bezel is a KL4 a 5watt Luxeon led capable of producing up to 100 lumen which puts the L4 as one of the brightest led flashlights you can get.

The beam of the L4 is a typical pure flood beam, that means the L4 produces a "wall of light" instead of a focused beam. This kind of beam is great for illuminating rooms or nearby objects but doesn't have the "throw" to light up distant objects. Small as it looks this flashlight can produce a lot of light.

The light is powered by 2 C123 lithium batteries, 3.7v rechargeables must not be used since that can damage the led, if you want to use rechargeables you should get a 17670 protected rechargeable lithium-ion battery. The runtime on regular 123 batteries is about 1 hour.

In some forums you might also be able to get a 2 stage tailcap switch that will make the L4 a two stage light with a extremely long runtime in low and extremely high brightness on high. The two stage tailcap with the 17670 rechargeable battery make the L4 one of the nicest EDC lights you can have.

You can read specs for the L4 in Surefire's website. And you can order ir for $165 from this site.
