You're out after prawns or squid and the water's gone black. A standard white light won't pull them in. Green does. This one packs 72 green LEDs behind a durable IP67 waterproof case and puts out 1,296 lumens — enough to turn a dark bay into a feeding zone. Clip the alligator leads straight onto a 12V battery or plug into your cigarette-lighter socket. Got a permanent setup? The inline waterproof plug and socket let you run the cable through a 19mm hole and lock it in. One thing to note: this light is very bright. Keep it under the waterline while it's running. Running it out of the water can overheat the LEDs
