Fluorescent bulbs use less battery power than any of the others.about 1 amp so that means taking only one battery for me. and staying all night .I use 2 green underwater ,1 white above water of them. 1 white above the head so you can see in the boat.The bad part is they break easy . very costly at 30.00 a pop when broken.Green or white like everone has said I cant see any difference . Some float some sink.well here we go again mater of opinion ,above the water you can see your corks ,the sinker is harder to see the corks but lights the water up brighter with less glair.
The star light work really good and are compact . use more current but not sure how much, and will blow if pluged in while not in the water.Super bright though.
12 volt bulbs.The light bulb type, most are 50 watt lamps. Use 4.1 amps which if you are using more than a couple that can really add up quick.
I have seen 12 volt fluoresent screw in lamps on the internet but have never used any.
But I dont know which is best or which will help you catch more.
I think the more you go the more you will catch.
