When I started thinking about writing this post in 2013, Malkoff Devices had just expanded their product line with a few LED conversions designed for use with Surefire E-series lights and Surefire Scout Light Weaponlights.
Now the Malkoff E-series/Scout light range spans nine heads from superthrow, high output heads to a specialized Bodyguard V2 head (with greater than 1000 lumens for 10 seconds) and a three mode LiIon rechargeable battery powered head.
My early E2/Scout head has an input voltage of 3.4-9 volts. I run it on a Vital Gear FB1 or my Surefire E1B with a RCR123 battery. I compared it to my Malkoff M61 in a VME Malkoff Valiant Concepts Head, which is also designed for an input voltage of 3.4 to 9 volts. My M61 uses a Cree XP-G LED, compared with the current M61 which uses the XP-G2. The M61 has a slightly larger hotspot and in my sample while the E2/Scout head’s beam was slightly more neutral.
Currently, I carry a Vital Gear FB1 or Surefire E1B with the Malkoff MDC LMH. With three modes (15 lumens/80 lumens/400 lumens), the LMH is a little more versatile. It’s also slimmer than the Valiant head with the M61 and I can carry it clipped inside my front pants pocket.
When I read that Surefire was discontinuing the incandescent lamp Surefire E2D flashlight, I found a good deal on a new one. I liked the ability of the E2D to tailstand, that is, on a flat surface, the flashlight will stand vertically on the tailcap.
I decided to make a couple of mods to the flashlight too – modifying the strike bezel so it wasn’t so sharp; changing the switch in the tailcap and replacing the incandescent lamp with an LED.
I wasn’t really in need of the defensive capability of the crenelated Strike Bezel®, so I used my Dremel’s cut-off wheel to grind down the bezel so it wouldn’t be so aggressive toward the inside of my pocket. I used a Birchwood Casey Super Black™ Touch-Up Pen on the bare aluminum.
I read that the McClicky switch is a direct screw-in replacement in the discontinued Surefire Z52 twisty switch but using it in Surefire Z57/Z61 tailcaps requires some modification. I assumed the inner construction of the E2D tailcap was similar to the Surefire Z57/Z61 and the Z68 tailcaps.
Most of the E-series/McClicky modifications I found required a 11/16 x 20 tap to cut more threads in the tailcap to correctly position the McClicky switch. In trying to find a way of avoiding buying a tap, I realized if I removed some of the threads on the McClicky switch to reduce the diameter of the front end, I could insert it from the rear of the tailcap housing. The modded switch stops in the correct position against a rim that was already machined in the tailcap and is held by the stock retaining ring.
The last mod was to replace the 25 lumen MN02 incandescent lamp assembly with an LED. The simplest and most expensive way to do this is to buy a Surefire KX2C (200 lumen single mode) head or a KX2 LED Conversion Head (3 lumen/60 lumen dual mode). Surefire sells these two heads for $150 (USD) each. That’s what I did with my Surefire E2E (KX2) but I managed to buy it on eBay for considerably less. Before arriving at this point, it may have been better to consider the (now discontinued) $189 (USD) E2D LED Defender® Dual-Output LED flashlight.
With the E2D, I thought I’d try the Veleno Designs Surefire E series incandescent to LED conversion three mode module. It’s essentially a brass heatsink with a neutral/warm Cree XP-G. The module fits inside the E2D bezel and the input voltage range is 1.8V to 5.5V (1 x CR123 or 1 Li-Ion rechargeable). I sanded the inner body of the flashlight with emery cloth so it accommodates a protected 17670 Li-Ion battery. The E2D flashlight is about .5 inches (12.7 mm) shorter than the E2DL.
The Veleno Designs module is “tested to provide 200 lumens of actual output.” Mine doesn’t seem as bright as my KX2 and I since I’m used to cool white LEDs, the neutral/warm color of this module seems green to me sometimes. I may get over it.
