It's simply a light designed to throw the light out a far distance. This tends to require a large diameter, deep reflector, although some lights have multiples of smaller reflectors which can work well (Imalent R90TS).
My FW21 X9L is a nice tiny thrower, but not exactly ideal if you're looking for a legit thrower. Although good, the beam isn't 100% perfect and it just can't do max power for very long. The single SBT90.2 LED is fine but you would need it to be placed in a larger reflector with more aluminum heat sinking with more batteries to have a better beam with longer runtime at high output.
