We’re not sure if this is a flood light or a spot light. It has a relatively narrow 18 degree beam. We know it is water proof as it has already seen a lot of spray at its mounting point on our forward “mast”. The unit we installed has a 1000 Watt halogen bulb.
The lighting diagram is shown above. It indicates a theoretical coverage of 1400 meters – almost a mile. We’ve not seen any evidence that it works this well. But we do know that it lights up a wide swatch an 1/8 of a mile ahead, with which we are quite pleased. This type of lighting is a compromise. If we’re coming into an uncharted anchorage at night because of a delay, that broad headlight affect, in conjunction with radar, is wonderful. However, it does not appear to be adequate for avoiding floating debris – at least that is our current feeling. A focused spot light might be better for debris watch, but this is a much more costly and complex solution, and one which does not illuminate a wide swatch of anchorage (it requires aiming). So, for our shorthanded purposes, we think this Hella light will get the job done on the rare occasion when we are caught out late in Alaska. And if we need a more focused beam, we have our super handheld unit.
