A very well taken care of Surefire E2L. This light is in great condition and working order but is missing two or three small pieces of anodizing from the head of the light which is only noticeable if looking for the blemishes, otherwise, it’s in great cosmetic shape and fantastic operational condition.  I had a few exciting enhancements made to this light.  It was bored out to accept 1x 18650 Li-Ion Batteries and a McClicky switch was installed in the tail cap.  The E2L head has the following:·         Triple LED configuration installed·         Internal module (“light engine” / “pill”) is made of 145 Tellurium Copper·         Triple CREE XP-E2 Torch LEDs mounted on a Noctigon copper MCPCB.  (LED tint is a very bright cool white and rated by CREE as having a 10,000k color temperature). MCPCB is directly reflow soldered to the copper "pill" for optimum thermal transfer.·         Direct drive FET driver from Mountain Electronics.  FET has Guppydrv Rev2 firmware loaded to it.  ·         The Carclo optic was modified to hold one 5x1.5mm tritium vial in each leg (Tritium vials not included in this auction, however, the buyer will can access the Carclo optic to install Tritium vials at a later time if so desired)·         Glow tape installed providing a post use ambiance (Picture included)·         7.5 Amp reading, at the tail cap when switched to turbo mode, indicates roughly ~2000 lumens out the front.  An AW IMR 18650 was used while testing the E2L's Amp output. (Note: No battery will be included in this sale)This light is a true pocket rocket!!These lights are not meant to be dropped and it is assumed that not much shock absorption is included.  Dropping the light could damage it, possibly to include permanent damage. In short, just try not to drop it!  :)It is not assumed that this light is water resistant and should not be placed into water intentionally. This light takes 1x 18650 Li-Ion IMR battery ONLY. The use of any other type of battery is at the users’ risk.  Note: No battery is included in this sale. The light will be shipped via USPS.  If you’d like to buy extra insurance, please reach out to me prior to purchase.  Will not ship internationally.
