Compact, but don’t let the diminutive size of the Bay Blaze fool you?this is one of the most powerful surface-mount, LED underwater lights available today. Measuring only 3 7/8" in diameter, the three ultra-bright LED elements of this light produce an output of 400+ lumens, yet draw only 760mA@12V (120mA@24V). Extending only 5/8" from the hull surface, the durable anodized aluminum housing and precision glass lens will stand up to years of exposure to cleaning agents, antifouling coatings and the hazards of the marine environment below the waterline. Completely self-contained LED design in rounded housing with countersunk holes minimizes the need for thru-hull drilling, requiring only three #10 stainless steel mounting screws (included) and a 1/4" access hole for wiring.
