The WELLUCK 12V Interior LED Light Bar is a slim, 1600-lumen COB light strip with an inline switch designed to deliver bright, space-saving illumination for cars, trailers, RVs, boats and cabinets.

Whether you need stable task lighting for a workshop, soft overhead light for an RV ceiling, or a low-profile fixture for a cargo area, this 13.38" x 0.8" x 0.67" COB LED bar balances brightness with a compact footprint. It runs on 12 volts, consumes only 3W per unit, and arrives as a 4-pack with multiple mounting options so you can fit it into tight spots without rewiring or bulky housings.

How bright is the WELLUCK COB light and what color temperature does it deliver?

The fixture outputs 1600 lumens of 6800K cool white light per bar, giving clear, high-contrast illumination for detail work or general interior lighting. The COB (chip-on-board) design produces an even light panel with minimal hotspots.

• 1600LM brightness for each bar — suitable for reading and repairs.
• 6800K cool white for crisp visibility and contrast.
• COB technology for uniform, shadow-minimizing light.

Can I install this LED strip in different vehicles and living spaces?

Yes. The WELLUCK LED bar is intentionally ultra-slim and versatile; you can mount it in cars, vans, trailers, RVs, boats, cabinets and more using screws, magnets, or included adhesive tape. The package includes hardware to support multiple mounting choices for different surfaces.

• Included mounting: screws, metal brackets, magnets and adhesive tape.
• Compact profile fits ceilings, under shelves, inside cabinets, and in tight compartments.
• Inline switch simplifies operation without modifying vehicle wiring.

Is this safe and energy-efficient for 12V systems?

The LED bar is engineered for low-voltage environments, drawing roughly 3W on a 12V supply, which reduces power drain on vehicle batteries compared with high-voltage fixtures. An aluminum alloy base helps dissipate heat and supports long service life without compromising safety in enclosed spaces.

• Works on standard 12V systems—ideal for cars, RVs, boats and campers.
• Low wattage (approx. 3W) minimizes battery load during use.
• Aluminum alloy housing improves thermal management and durability.

How long will the lights last and what comes in the box?

Each WELLUCK LED bar uses durable components and is rated for up to 50,000 hours of operation under normal conditions, giving years of reliable performance. The kit comes as a 4-pack with comprehensive mounting accessories so you can outfit multiple zones immediately.

• Estimated life: up to 50,000 hours per LED bar.
• Box contents: 4 LED bars, 8 magnets, 8 screws, 8 metal brackets, 8 adhesive strips.

Who is this for? The WELLUCK 12V Interior LED Light Bar is aimed at DIYers, vanlifers, RV owners, boaters, and anyone who needs bright yet unobtrusive lighting in small or enclosed spaces. It’s especially useful for people who want easy, low-power illumination for cooking areas, cargo bays, under-cabinet shelving, and vehicle interiors without major electrical work.
