Surefire EB1 Backup with Thyrm Switchback

08-16-2014 by: Mil-Spec Monkey

I've been rocking my old SureFire E1B backup light as a part of my EDC (every day carry) loadout for quite some time, but while wanting to try out using the Thyrm Switchback with it I was sad to see this model was not supported. Since Surefire doesn't make the E1B anymore this made sense design wise on the Switchback and ended up as a good excuse to try out the EB1. (Yes the names are a bit confusingly similar)

The purpose of the EB1 Backup, hence the name is meant to be a backup to a primary larger tactical light with the EB1 being a smaller easy to carry light that still has tactical light capability. Since there is never pleasing everyone with one light, they make 3 different variants of the EB1 to accommodate the majority of preferences:

Click-type switch without tailcap shroud `” Like the original E1B Backup. Partially press tailcap pushbutton for momentary-on high output; press further to click constant-on high. Return to off and press or click again within two seconds for low output. No shroud around switch. This version is best for non tactical priority daily activities.

Click-type switch with tailcap shroud `” Partially press tailcap pushbutton for momentary-on high output; press further to click constant-on high. Return to off and press or click again within two seconds for low output. Raised shroud around switch provides extra protection against accidental activation. This version is best for daily activities and you are worried about you pants or method of carry engaging the switch.

Tactical switch without shroud `” Partially press tailcap pushbutton for momentary-on low output; press further for momentary-on high output. Release to turn light off. (There is no click functionality) Twist tailcap clockwise partially for constant-on low then all the way for high output. No shroud around switch. Like the name implies this version is setup for tactical priority.

Besides only using one CR123 battery to offer a compact size, another big plus to the EB1 is the pocket clip. It is integrated well made of metal offering good durability and the reversible design allows mounting heads up or heads down. That said I find the heads up retention too loose in a pants pocket so only good for temporary placement, however the functionality works great for mounting to a ball cap to turn the light into a head lamp. As a small upgrade from the older Backup, the EB1 has a hole in the clip for a lanyard lash point.
