After deciding that lanterns were not for me and that if I was going to spend big $$$ to hear something make noise all night it was not going to be a generator; I chose this simple setup. I run this one at the front and it also doubles as a night navigation aid because it can easily be turned and tilted. I have another similar setup at the rear but on a slightly taller stem and sometimes I run a third light at the center of the boat off of the driver side just to light up the area behind me (the side that I don't fish from). During summer, I regularly run all 3 of these plus 2 hydroglow style submersible lights for 5.5 hrs on a group 24 walmart battery.
