That's what it should be called, but officially it is sold as the E2 Hyper Throw, a head designed to fit on E-series bodies and Scout 600 WMLs.
I updated the light below with this head, shown with a Bodyguard v.2 head which looks exactly the same;
The E2HT is rated at only 500 lumens but at 35,000 lux, compared to the Bodyguard at 1,000 lumens and about 12,000 lux. What this means is that the lumens of the E2HT are more tightly focused into brighter hot spot, but at the cost of a spill brightness. Here are a series of beam shots (by others) posted online comparing the Bodyguard to the E2HT (the first in each pair is the Bodyguard);
So far I am very impressed with the capability of the E2HT in the role of an EDC fight light. It is wickedly bright - anyone with dark-adapted vision within 20 - 30 feet who takes a direct hit to the eyeballs is going to have their OODA loop seriously reset. The only light in my collection that is brighter is the Hound Dog Super, which is physically a much larger light.
As I have shown before, I carry this light in a Kytex Gear horizontal holster designed for the SF 6P;
"Light Saber" seems a fitting description.
