I have two of the sea view lights. They are very nice, and very brite.
They will bring the squid up to the boat. They certainly will kill your batteries though. They are just like leaving the head lamps on your car on. They will kill a good battery in 30-40minutes. I leave my engine just above idle 850-900 rpm which makes them even brighter yet. Performance is great, but you will have to leave your engine on.
Thats the draw back. BIG TENTACLES OUT !!!
