Thanks for the input. I have catalina 22 and the only purpose of the light is so I can anchor and not have to pay dockage fees.
As for the light setup. I think I like the suggestion by Mainesail with the Polarstar bulb and Aquasignal 40. The reason is, if the bulb burns out, I can easily change it. I am not sure about the OMG light. If it has a changeable bulb or not, I can't really tell.
If I go with the aforementioned setup, what size amp hour battery will I need to get? And what type/size (watts/amps/volts) of solar charger will I need to keep the battery up? Correct me if I am wrong, but with the apparent 1 watt rating of the bulb the draw on the battery is minisucle and can easily stay on all the time as long as I get a decent battery/charger.
College math apparently did me little good!
Again thanks for the input.
Link to photodiode switch that I was considering. But it is probably unneccesary with the right battery/charger.
