I have a small 14' jon boat and do not have room for a genny as all so I had to go the 12 volt way. I went to Walmart and bought 3 sets of 2-12 volt lights. I then mounted them on some small brackets that I already had. You have to use 12gauge braded wire to tie them together, and make sure that you have a fuse in somewhere. Then I have two deep cycle battries tied together in parallel. That is positive to positive and so on. I get just over 4 hours of solid running. It gives you enough light, but you do have 6 spots. Not a full flood like with halegen lights. It gets the job done, and cheap, I have less than $100 not counting the batteries. Since then I have found out that golf cart batteries are the best if you can find any.
