Overview

The i2Systems APL-2W-65K-PW41 is an Apeiron A3101Z recessed LED downlight that runs on 9-30V DC and draws 2.5W to produce 6500K cool white light.

It mounts with three screws and a removable bezel, which makes it easier to service later or swap finishes without pulling the whole light. The housing is stainless steel, the trim is brushed nickel with a PVD titanium coating, and the lens is tempered glass with a diffuser for smooth, even output.

This fixture is IP67-rated for wet locations, but it is not intended for submersible installs or any spot where water can sit around the light.

Key features

• 9-30V DC input for typical 12V and 24V onboard electrical systems.
• 2.5W white LED with 6500K cool white output for clean task lighting.
• IP67-rated for wet locations; not rated for submersion or areas with standing water.
• Screw-mount installation with removable bezel; shallow 1.07 in (27 mm) mounting depth helps in tight overheads.
• 3.50 in (89 mm) face with a 2.59 in (66 mm) mounting hole; three screw holes on a 3.12 in (79 mm) circle.
• Stainless steel housing, brushed nickel PVD titanium-coated trim, and a diffused tempered-glass lens.
• Built-in transient protection and reverse polarity protection.

Compatibility and fit

Confirm you have room for the 2.59 in (66 mm) cutout and the shallow 1.07 in (27 mm) depth behind the mounting surface, plus space for wiring and connectors. The 3.50 in (89 mm) face covers the cutout, and the light fastens through three equally spaced screw holes.

On most boats this ends up under a hardtop, in a pilothouse headliner, or in a cockpit soffit where you want overhead light that reads crisp and cool.

Installation and wiring

The fixture uses 18 in twisted 18 AWG leads. Wire red to DC positive (9-30V), black to common ground, and use the yellow lead only when you are integrating a compatible dimming control. Keep the dim control line within 5V max and insulate any unused control lead so it cannot short.

In damp or exterior locations, keep splices and junctions protected, support the cable so it cannot chafe, and seal penetrations so water cannot migrate into the headliner or wiring cavity.

Electrical and dimming

Plan for about 208 mA per light at 12V DC and about 104 mA per light at 24V DC when sizing circuits. If you are using an i2Systems LightLink dimming module, a single dim line can control multiple fixtures, and the control hardware should be mounted somewhere you can still access for troubleshooting.

Use on board

This is a good match for owners who want a cool-white overhead light for instrument areas, work surfaces, or cleaning up the cockpit after dark. If you are mixing lighting across cabins and lounges, keep in mind that 6500K reads noticeably cooler than warm-white fixtures.
