Lumitec SeaBlaze Quattro LED Underwater Light White/Blue 2000+ Lumens – 101511 is a compact, surface-mounted marine lighting solution designed to illuminate the water around boats and other marine vessels. Producing more than 2,000 TRUE measured lumens, it delivers bright white and blue illumination for improved underwater visibility, an attractive stern appearance, and a distinctive lighting effect while the vessel is anchored, docked, or operating after dark. Its dual-colour output and multiple operating modes, including cross-fade, allow boat owners to change the atmosphere without installing separate white and blue lights.

This Lumitec underwater light operates from a wide 10–30V DC input range, making it suitable for common 12V and 24V marine electrical systems. Current draw is rated at 2.1A on 12V DC and 1.1A on 24V DC, with a total rated power of 25W. The white output has a correlated colour temperature of 6500K, producing a crisp, cool-white appearance, while the blue mode creates a striking underwater glow. A CRI rating of 70+ supports clear and consistent white illumination around the installed area.

Designed for permanent marine installation, the SeaBlaze Quattro features a marine-grade bronze housing. Bronze provides a strong and dependable structure for equipment fitted on the exterior of a vessel below the waterline. Its low-profile, circular body measures 3.85 inches in diameter and only 0.71 inches deep, helping it fit neatly onto suitable transom and hull surfaces. The surface-mount design requires a 0.5-inch-diameter opening for the cable rather than a large through-hull cut-out, simplifying installation while preserving a clean exterior appearance.

As an underwater boat light, the SeaBlaze Quattro can be installed on suitable flat mounting areas where it will not interfere with engines, rudders, trim tabs, propellers, or other vessel equipment. Proper orientation is important for distributing the wide light pattern toward the water surface. All mounting holes and the cable entry must be carefully sealed with an appropriate marine-grade sealant intended for below-waterline applications. The light should also be connected to a correctly protected DC circuit and installed according to Lumitec’s instructions by a qualified marine installer.

The combination of useful output, dual-colour operation, compact dimensions, and broad DC voltage compatibility makes this marine underwater light practical for powerboats, motor yachts, fishing boats, leisure craft, and other compatible vessels. White illumination can support general visibility around the stern, while blue illumination can be selected when a more atmospheric effect is preferred. The cross-fade function provides a smooth transition between the two colours for additional visual interest.

This SeaBlaze underwater light carries a five-year warranty and combines its LED light source, control functions, and bronze body in one compact fixture. For buyers looking for a Lumitec underwater light that provides white and blue modes without requiring a complicated multi-fixture arrangement, model 101511 offers a straightforward solution for enhancing a vessel’s underwater lighting system.
