The AAA Round RGBW Underwater Light – Surface Mount is a compact, round marine underwater LED light designed for installation on the exterior of a vessel in a below-waterline lighting position. It is supplied in two material variants: an anti-corrosion, chemically resistant polymer version and a plastic version with an S.S.316 stainless-steel trim ring. Both versions use the same round 119.4 mm diameter format and surface-mount design, allowing buyers to choose the finish that suits the appearance and installation requirement of their boat.

At the centre of this RGBW underwater light are nine high-power “4-in-1” RGBW LEDs. The RGBW arrangement provides separate white, blue, green and red light selections, so a boat owner can change the visual effect without replacing the fixture. Colour selection is made by operating the connected switch ON and OFF. Manufacturer data lists effective output of 696 lm in white, 246 lm in blue, 878 lm in green and 383 lm in red. On the stainless-steel trim-ring version, the maker also lists fast and slow strobe modes, selected through the switch sequence. This makes the fixture a practical choice for owners looking for RGB underwater lights that can move between a clean white appearance and colour-led underwater illumination.

The light operates on 10–30 VDC and carries an IP68 rating for submerged use. The manufacturer lists a 23.6 mm thickness for the 119.4 mm diameter housing. The polymer model is listed with a 120° beam angle, while the plastic and S.S.316 trim-ring variant is listed with a 75° beam angle. These distinct beam angles are important when ordering: select the polymer version where a wider spread is preferred, or verify the selected trim-ring model where a more directed beam is required. Both versions are intended as surface-mounted under boat lights for the exterior hull area and should be installed in line with the vessel’s electrical and hull-installation requirements.

For boat owners, builders and marine service teams, this round RGBW underwater light helps create a distinctive illuminated waterline around a vessel at night or while moored. It can be considered for recreational boats, yachts, sport-fishing boats and other marine vessels where underwater marine lights are wanted as part of the vessel’s exterior lighting layout. The compact circular shape suits applications where a round fitting is preferred, while the dual material options offer a choice between a polymer housing and an S.S.316-trim presentation. Whether used as a single fitting or planned into a multi-light layout, it brings selectable RGBW colour capability to a surface-mounted marine lighting position.

FAQs:

Q: What is the difference between the two versions?
A: One version uses anti-corrosion and chemically resistant polymer. The other uses a plastic housing with an S.S.316 stainless-steel trim ring. Both are 119.4 mm round RGBW surface-mount lights with the same stated colour outputs and 10–30 VDC range.

Q: Which colours can this underwater light display?
A: It provides white, blue, green and red light. Colours are selected by operating the switch ON and OFF. The trim-ring version also has manufacturer-listed fast and slow strobe modes.

Q: What are the light outputs for each colour?
A: The listed effective lumen values are 696 lm for white, 246 lm for blue, 878 lm for green and 383 lm for red.

Q: Is this a surface-mount underwater boat light?
A: Yes. It is described as a round surface-mount underwater light for use on a vessel’s exterior underwater lighting area. Confirm the chosen variant’s beam angle and installation requirements before fitting.
