Perko Surface Mount Dome Light - 5" O.D.(4" Lens) - Chrome Plated

The Perko Surface Mount Dome Light with 5" O.D. base and 4" lens in chrome plated finish is a marine-grade interior lighting fixture engineered for reliable performance aboard vessels, RVs, and compact enclosures. Built with a bronze base and brass body, this dome light delivers even illumination across a wide viewing angle and is engineered to operate seamlessly across standard marine electrical systems rated 12, 24, and 32 volts.

Specifications reflect a fixture optimized for space-constrained cabin and galley installations. The 1-7/8" depth allows flush mounting in overhead panels or bulkheads where overhead clearance is minimal. The 4" lens diameter provides broad light distribution, while the 11-watt standard bulb operates efficiently at typical marine voltages; maximum wattage rating of 17W supports brighter incandescent or LED substitutes as needed. The polished chrome plating resists corrosion in salt-air and high-humidity marine environments far better than bare brass or unfinished metals, a critical durability factor for extended offshore use.

This fixture suits galley lighting, cabin ceiling mounts, engine room inspection lighting, and navigational interior spaces on cruising sailboats, fishing vessels, offshore platforms, and recreational marine craft. It is equally applicable to mobile RV applications and industrial cabinet lighting where multi-voltage compatibility and corrosion resistance are required. The 5-inch mounting footprint and standard 4-inch globe base are compatible with legacy Perko installations and retrofit upgrades on vessels with existing dome light infrastructure.

Perko surface mount dome lights remain industry standard aboard commercial and recreational vessels due to their proven longevity, simple installation, and availability of replacement components. The multi-voltage design eliminates the need for separate fixtures across different electrical systems, simplifying inventory and spares management for marine operators managing mixed-fleet operations.
