This light, already in its original state, offers an incredible range from flood angle to very tight spot, nearly 4%.
The amazing fact is that by adding the DPBA-14, the non-spherical parallel beam adapter, you put the light head in a position of full flood or near full flood, and the light output is two times or even more in comparison to the original light output in its spot position.
This, making it a very useful, very powerful, very clean beam. Stray light can be diminished by a honeycomb front attachment for the parallel beam attachment.
