Facon 6-Pack Ultra Slim 4.5ft 12V RV Puck Lights w/Switch - Efficient

In this review the Facon 6-Pack Ultra Slim 4.5' 12V RV puck lights are assessed for small-space RV and marine interior use; the bottom line is they are a practical, efficient replacement for bulky dome lights because they deliver bright, neutral 4000K illumination while drawing very little power. The reviewer found these lights easy to install, smartly designed for tight spaces, and notable for the individual on/off switch that adds convenient control during trips.

Key Features

• Ultra-efficient power: The 4W smart LED design reduces battery drain so an RV or camper can stay powered longer between charges or shore hookups.
• Comfortable daylight white: At 4000K and about 290 lumens each, the lights provide clear, usable illumination without harsh blue glare for reading maps and finding gear.
• SlimFit stealth design: The 4.5' diameter and low 1' profile fit into cabinets and curved ceilings where thicker fixtures fail.
• Simple quick install: Align, screw, and connect two color-coded wires (black positive, white negative) so most installs take only minutes with no special electrical skills.
• Durable construction: An aluminum base for heat diffusion and a frosted shatterproof lens help the fixture withstand vibration and marine humidity.
• Certified safety: cETL certification confirms the light meets electrical safety standards for RV and boat interiors on 12V DC systems.

Who It's For

These puck lights are aimed at RV owners, vanlifers, and boat owners who need low-profile interior lighting that conserves battery power while delivering usable daylight-white light. They suit anyone replacing older incandescent dome lights or adding lighting to cabinets, narrow corridors, and tight bezels where depth is limited.

Those who should look elsewhere include people seeking variable color temperatures or smart-home integration, since these are fixed 4000K fixtures with a manual switch. Also, if absolute ultra-high output is required for workshop-style tasks, a higher-lumen dedicated work light would be a better fit.

Pros & Cons

Pros

• Bright, neutral 4000K light that improves visibility without harsh blue tint.
• Very low power draw from the 4W LED design, helping preserve RV battery life on multi-day trips.
• Super-slim 4.5' diameter and 1' profile fits tight spaces and installs fast with two color-coded wires.
• Built solidly with heat-diffusing aluminum base and shatterproof lens for vibration resistance.

Cons

• Some users report occasional flickering with aging units or marginal wiring, so installation quality and vehicle wiring condition matter.
• Fixed 4000K color temperature may not satisfy users who want warm or tunable lighting options.

Specifications

Our Verdict
