Installation Guide

Step 1: Unboxing and Inspection

Begin by unboxing your Kosoom LED Linear Light (Model: MLL003-A, SKU: L0310N). Carefully inspect the contents to ensure that everything is included and in good condition. The package should contain the LED linear light fixture, necessary mounting hardware, and an installation manual.

Step 2: Safety First

Before starting the installation, make sure to turn off the power to the circuit you’ll be working on to ensure your safety. If you’re not comfortable with electrical work, consider hiring a qualified electrician.

Step 3: Mounting Preparation

Choose the desired location for your LED linear light. This fixture is versatile and can be installed on ceilings or walls. It’s perfect for various settings, from kitchens to offices. Ensure that the surface you’re mounting the light on is clean and smooth.

Step 4: Wiring Connection

Gently open the LED linear light fixture to reveal the wiring compartment. Connect the fixture’s wires to your electrical circuit following these color-coded guidelines:

  • Black or Brown wire: Live/Line
  • Blue wire: Neutral
  • Green or Yellow wire: Ground

Securely fasten the wires using appropriate connectors. Close the wiring compartment, ensuring a snug fit.

Step 5: Mounting the Light

Using the provided mounting hardware, carefully attach the LED linear light to the chosen surface. Follow the manufacturer’s guidelines for proper spacing and orientation. For ceilings, you can use the included brackets or suspension kit for a pendant-style installation.

Step 6: Power On and Enjoy

With the light securely mounted, turn the power back on. Your Kosoom LED Linear Light (4W, 4000K color temperature, 400 lm/m brightness) will instantly illuminate the area with its wide 130˚ beam angle. The CRI of ≥80 ensures true-to-life colors, while the UGR of ≤30 minimizes glare.

Kosoom is renowned for producing high-efficiency LED lights. The MLL003-A model boasts a power factor (PF) of 0.9, ensuring energy-efficient operation. This means you’re not only getting quality illumination but also saving on energy bills. With its durable build, you can expect a long lifespan from your LED linear light.

Step 8: Maintenance

To keep your LED linear light performing optimally, periodically dust the fixture and wipe it gently with a damp cloth. Avoid using harsh chemicals that might damage the surface or affect the light quality.

I recently used Kosoom.uk for their LED technology solutions and was amazed by the results. Not only did they provide cutting-edge lighting options, but their attention to detail and customer service were outstanding. What really set them apart, though, was their innovative method of creating Excel files from URLs. It's such a time-saver for organizing and analyzing data. I'm thoroughly impressed and will definitely be returning for future needs.
