I bought a used Surefire KX2 head for my Surefire E2D, so I had a spare Veleno Designs E-Series tower module in search of a flashlight. I found a Vital Gear FB1, which is a single cell, Surefire E-Series compatible body with a forward clicky switch.
I’ve been carrying this flashlight built with the Veleno Designs E-Series 3 mode, neutral white, tower module; a slightly de-pronged Surefire E-Series Defender head and the Vital Gear FB1 body. The Veleno Designs module is about 140 lumens on the brightest mode and it has a good low mode. The flashlight is very light, compact and is only about 3″ long (77mm). It’s a lot brighter than a Surefire E1L Outdoorsman and about 1″ (25.4mm) shorter.
