Hella Apelo A1 Blue/White Underwater Light, 1800 Lumens

The Hella Marine Apelo A1 is an 1,800-lumen underwater light in a black housing with a white lens, running blue and white output rather than full RGB.

Blue and white is the two-color version against the full RGB models in the same range, and it costs less for the colors most boats actually use. White for working over the side and blue for ambient or fishing covers the majority of use. Full RGB adds greens, reds and transitions that look impressive and get selected rarely.

Where green matters is stained or tannic water, which is worth checking before ruling out the RGB version. Blue penetrates clear and salt water well; green does better where the water is dark, so freshwater fishing on a stained lake is the case that argues for full color.

Optical intelligence spreads light wide horizontally while staying narrow vertically, creating the underwater effect. The corrosion-resistant thermal polymer housing takes a high-strength Grilamid nylon lens, in black with a white lens. Explore more underwater lights.
