You have several LED options.
1. You have the Surefire factory LED heads available. The current versions are the
KX2 and the
KX2C both of which are $150.00. I do not own either. I do have the older KL1 model which has a very narrow beam that throws exceptionally well but has NO spill. I am not particularly fond of this head due to it's narrow focus but does work well at distance.
2. You have the
OpticsHQ TLS Cree Q5 LED conversion head. Cost is $80.00. I own two of these.
3. You have the NEW
LumensFactory E Series XPG Head Unit. Cost TBD. Just became available. I do not own one.
4. You can get the
Veleno Designs E series drop in and
here in one, two and three levels and cool or neutral LEDs. I have one of these.
The OpticsHQ head makes the E2e larger since it replaces the original bezel but the LED is VERY bright with a great hotspot and good spill. It has become one of my favorites for output. It will run for two hours at this level.
The Veleno LED fits INSIDE the E2e head like the bulb. This option keeps the E2e the same size as original. Mine is the a single level output (high) with a neutral LED. It has great spill and is very useful for close to medium distances. I like it most because it keeps the E2e the same size. Very pocketable.
IF your E2e's battery tube(s) will fit a protected 17670 li-on rechargeable battery (not all do), you could use it with a Lumens Factory EO-E1R incandescent (3.6V, 90 Lumens) Extreme High Output Lamp Assembly. It will give you about the same output as your current E2e but since it is rechargeable will be much less expensive over time. You will also be able to use this rechargeable with many of the LED heads as well.
