We have created the worlds first true high power led underwater kayak fishing lights. Each 12led/36watt lighthead uses our custom built high power led boards using only the best cree 3535 high power leds. We cnc machine and laser cut all our own materials for complete control over quality and design. We use only American made materials except for the leds which we have to get overseas due to our country not producing them anymore. The lightheads are completely epoxy filled with special optical grade high temperature epoxy which will never yellow or age. You can bash these lights into the bottom without ever worrying about damaging them. The only way to damage them is to run them out of the water for >10-15 minutes. They do need the water for cooling as we run these strong. We also use military grade M27500 teflon cable for extreme toughness. We let you put any connectors on the positive and negative wires of your choosing. Our lights use no electronics which can fail. I design the boards for direct hookup to a charged standard 12vdc battery or a very compact lithium RC 3S cell or 11.1vdc. The lights are held very securely to the bottom of the hull with heavy duty marine grade bungee cord and adjustable snap hooks on the ends. It takes all of seconds to install and take off. You can cut to fit your boat perfectly. Each lighthead produces around 2500 lumens each compared to your car's 55watt halogen headlights at 1500 lumens each on high. So this is just like having your car headlights under your boat. Green is great for attracting fish to you while white is great for overall viewing of aquatic life. It is amazing what you see at night cruising the estuaries, river and inlets at night. Great for tour guides also. Imagine cruising alone and gigging all those flounder-limits in no time. Also allows you to be seen at night for increased safety! Perfect for striped bass fishing from your kayak. The lights can also be wrapped around a small aluminum pram style boat for gigging. Please call for any additional information and remember you saw these here first. You will be hard pressed to find any nicer lights. Full 2 year warranty excludes return shipping, running light out of water and activating 150f thermal sticker or hooking up to anything other than a 12vdc non charging battery (battery not being actively charged like with an alternator).
