T-H Marine Extreme LED Underwater Light, Green, Surface Mount, Oval 3.5 x 1.5 Inch

The T-H Marine Extreme LED Underwater Light (LED-SM173COB-G) is a surface-mount underwater light built for anglers and boaters who want a brighter, more durable light than standard underwater fixtures. This green model is finished in an oval 3.5 inch by 1.5 inch housing made of high impact polymer construction, so it stands up to constant exposure to water, sun, and vibration without cracking or clouding over.

This Extreme LED is rated 20% brighter than T-H Marine's own Standard LED Underwater Light, and the manufacturer states it is brighter than competitor underwater lights of the same size, giving a stronger green glow for attracting baitfish or simply lighting up the water around the boat or dock. It is completely waterproof and is designed to be used either underwater or above the waterline, giving flexibility in how and where it is mounted.

Built-in polarity protection means the light will not be damaged if the wiring is connected in reverse, and thermal protection guards the LED and driver circuitry against overheating during extended use. The surface-mount design allows installation directly to a hull, transom, or dock surface without through-hull drilling required by flush-mount lights, making it a straightforward add-on for boats and docks alike.
