Arcon 20669N 12V LED Ceiling Light, Clear Lens

The Arcon 20669N is a single LED ceiling light built for 12-volt interiors, and it's the kind of no-drama fixture you install once and forget about. Bright white SMD LEDs, a clean Euro-style white base, and a clear squeeze-off lens. That's the whole story, and for most cabins and coaches that's exactly what you want.

It measures 7-1/4 inches long by 4.95 inches wide, so it fills a ceiling or headliner spot without looking undersized. The bright white light reads crisp and neutral, good for reading a chart at the nav station, cooking in a galley, or just finding your gear after dark. Because it's LED, it draws very little current and runs cool. You can leave it on all evening without worrying about it cooking the headliner above it or pulling down your house battery the way an old incandescent dome light would.

Wiring it is straightforward. It's a standard 12-volt DC fixture, so it ties straight into your existing house circuit. Run positive and negative to the fixture, mind your polarity, and you're done. On longer runs we like 16 to 18 AWG tinned wire and an inline fuse sized to the circuit, which keeps the light bright at the end of a long pull and protects the wiring. If you're mounting into a thin headliner or fiberglass panel, back the screws with washers or a small backing plate so the fixture doesn't pull through over time.

The clear lens is the defining feature of this version. It squeezes off in seconds for cleaning or to get at the LED board, then snaps right back. A clear lens throws the most light, which is great in a darker cabin or a work area. If you're lighting a bright white interior and want a softer feel, know that a clear lens puts out a more direct light than a frosted one. For a galley or a reading spot, most folks love it. For mood lighting over a settee, you might prefer something diffused. Worth thinking about before you pick your spots.

The single on/off switch lives right on the fixture, so you don't have to wire it to a remote panel switch if you don't want to. Flip it at the light. That makes it easy to add task lighting exactly where you need it, a locker, a head, a bunk, without running switch legs all over the boat. And if you'd rather run it off a panel, you still can. The built-in switch just gives you the option.

Who's this for? Anyone updating a 12-volt interior. It's a natural swap for a tired incandescent dome light in an older boat, and it's just as at home in an RV, a trailer, or a camper. New builds too. The bright white output and low draw make it an easy default when you're wiring up cabin lighting from scratch. It's a single-fixture light, so plan on one per spot you want lit rather than one fixture covering a whole cabin.

A few honest notes. This is the clear-lens version, so if you specifically wanted a frosted or diffused look, that's a different part. And at 7-1/4 inches long, measure your existing cutout before you commit. If you're replacing a smaller round dome light, the footprint here is larger, and you may need to adjust or cover the old opening. Nothing hard, just measure first so you're not surprised at the panel.

Bottom line, it's a simple, efficient, bright white 12-volt ceiling light that does its job and gets out of the way. Easy to wire, easy to clean, easy to live with. Exactly what you want overhead when you're settling in for the night.
