Please note that this is the neutral white flood version of the HC51 and the specs below are for the regular H51w. The H51Fw has a frosted lens, which does a great job of smoothing out the beam and making a very nice flood light, but it greatly reduces throw.
This light has 3 main levels (High, Medium, and Low). Each main level can be configured to one of its two sub-levels. The second sub-level of the HighÂ can be further configured to different brightness levels or strobes.
