EPIK Underwater Transom Light | RGBW (With Internal Controller)

Take your vessel's underwater lighting to the next level with the Plash EPIK Underwater Transom Light with an internal RGBW controller, a high-performance marine LED light engineered for serious boaters who want exceptional brightness, durability, and reliability. Designed for both freshwater and saltwater applications, the EPIK produces an impressive 5,258 lumens of underwater illumination, creating a vibrant glow behind your boat while enhancing visibility around docks, swim platforms, and fishing areas.

Built with a rugged 316 stainless steel housing, the EPIK is designed to withstand harsh marine environments and years of continuous use. Its compact surface-mount design allows for a simple installation requiring only a small wiring hole through the transom, eliminating the need for large hull penetrations while maintaining a clean, professional appearance.

Whether you're attracting baitfish during nighttime fishing trips, illuminating the water around your dock, or creating a premium custom look for your vessel, the EPIK delivers powerful performance with low power consumption. Featuring an IP68 waterproof rating, advanced LED technology, and a 50,000+ hour lifespan, this underwater transom light is built to provide years of dependable operation.

Ideal for center consoles, bay boats, offshore fishing boats, pontoons, deck boats, and cruisers, the Plash EPIK combines powerful illumination with marine-grade construction to create one of the most versatile underwater boat lights available.

A RGB or RGBW controller is not required for these lights and they will not tie into an existing RGB/RGBW controller because they are controlled internally and only require a quick press of the switch to change the color/pattern.

Instructions for Mode Change

Mode 1 - Full Color Fade [DEFAULT]:

Power on the light and it will go into a fast "full color fade" cycle (15 seconds).  During this color fade mode you can freeze a specific color by quickly switching the power Off/On (under 1 second), this will lock in your specified color choice.  If no action is taken after the initial 15 seconds the light will go into a slow "full color fade cycle" (3 minute loop). 

Mode 2 - Solid Color:  

While in Mode 1 (Full Color Fade) toggle the power switch off for over 1 second but no longer than 5 seconds then turn it back on. The EPIK transom light will then be in "solid color" mode starting with white. Solid colors can be cycled through by quickly toggling the power switch ON/OFF (within 1 second).

Solid Color Mode Cycles in this order:

White -> Red -> Green -> Blue -> Yellow -> Purple -> Cyan -> REPEAT

Mode 3 - Full Color Strobe:

While in Mode 2 (Solid Color) toggle the power switch off for over 1 second but no longer than 5 seconds then turn it back on. The light will then be in "Color Strobe Mode". The EPIK light will automatically jump through 7 solid colors. Cycle the power off for a long hold (over 1 second) to change to the "Full Color Fade" mode.

Notes:

- Cycle power for UNDER 1 second to change the SOLID COLOR

- Cycle power for OVER 1 second to change the MODE

- Power OFF for OVER 5 seconds to RESET
