I like the green lights. I sink it about 5 ft under the surface most of the time but will leave it floating if the water is dead calm. The light helps you see your rod tips better. Also you can use the green lights out of the water and they don't take as much juice to run them all night. the white halogen lights get too hot to use out of the water and use a lot more juice. I can run two green ones for two trips before having to recharge that battery. One white light for one night.
