Many people revere the Surefire E Series lights for their compact size and durability. For years, these lights were only available with incandescent bulbs and the selection was fairly limited. Lumens Factory stepped in and began providing a variety of quality bulbs that were compatible with the E-series lights. Now they are doing the same thing with LED conversions.
The Lumens Factory E Series LED products are different than any other conversion that I have seen for the Surefire E Series lights. Rather than a self contained drop in head that can never be upgraded, Lumens Factory gives you options. They make an E Series bezel that accepts a number of LED modules that have a variety of features and outputs. These features include different input voltage ranges so that they can be used with different battery configurations and different output modes like single or 3 (high, medium, low) mode configuration. These head use Cree XP-G, R5 LEDs so the output should be impressive.
LED technology seems to improve daily so users who like to have the latest technology will appreciate the modular nature of these heads. Rather than buying a whole new head when the latest LED comes out, you can simply replace the LED module.
These are some impressive LED conversions. Check them out on the Lumens Factory website.
