Tired of harsh LED glare that strains your eyes, spotty light dots ruining your decor, or complicated installations? Our Diffused Light Bar is designed to solve these pain points—delivering seamless, eye-caring soft light that elevates any space while being easy to use and built to last.

Crafted with a built-in high-transparency diffuser and evenly spaced premium LED chips, this light bar eliminates hotspots and dazzling glare instantly, casting a 120° wide beam of flicker-free illumination. With a high Color Rendering Index (CRI ≥ 90), it reproduces true colors—perfect for kitchen under-cabinet lighting (no more shadowy countertops while cooking), bedroom ambient glow (warm white 2700K helps you unwind), retail displays (makes products look vibrant), or bathroom vanities (IP65 waterproof version resists humidity).

Installation takes 5 minutes tops—no tools or wiring skills needed! Peel off the industrial-strength 3M adhesive backing (holds for 5+ years on smooth surfaces) and stick, or use the included mounting clips for uneven areas. Cuttable every 3 LEDs (marked with scissor lines) to fit your space, from 1ft to 10ft lengths. Choose from warm white, natural white, cool white, or RGB full-color versions—dimmable options let you adjust brightness from 10% to 100% to match any mood.

Built for durability and safety: Flame-retardant PCB board + IP65/IP67 waterproof rating (optional) withstands daily use and humidity; low-voltage (12V/24V) operation is safe for kids and pets; 12W/metre power consumption saves 80% on electricity vs incandescent lights, with a 50,000-hour lifespan (10+ years of use).

CE, RoHS, and FCC certified for safety, backed by a 2-year warranty and 24/7 customer support. Join 10,000+ happy customers who’ve upgraded their lighting—no more glare, no more hassle, just beautiful, uniform soft light. Whether you’re refreshing your home or enhancing a commercial space, our Diffused Light Bar is the reliable, cost-effective solution you’ve been looking for.

1. Ideal Applications

Our Diffused Light Bar is designed for versatile use in residential and light commercial spaces. Perfect applications include:

• Home Lighting: Under-cabinet (kitchen), bedroom ambient glow, TV backlighting, closet lighting, stairwells, bathroom vanities (IP-rated versions), ceiling coves, and bookshelf lighting.
• Commercial Use: Retail display cases, boutique window displays, hotel room decor, office task lighting, museum exhibits, and restaurant accent lighting.
• Decorative Scenarios: Holiday decorations, wedding venues, DIY craft projects, custom furniture lighting, and event backdrops.

2. Installation Preparation

Tools Needed (No Special Equipment Required)

• Clean cloth (for surface preparation)
• Scissors (for cutting cuttable models)
• Optional: Mounting clips (included), power drill (for uneven surfaces), waterproof tape (for IP-rated cut ends)
• Required: Compatible 12V/24V power supply (not included; recommend our branded adapter for optimal performance)

Surface Requirements

• Choose a smooth, dry, and dust-free surface for adhesive installation (wood, metal, plastic, glass, etc.).
• For uneven or textured surfaces, use the included mounting clips for extra stability.
• Avoid greasy, damp, or porous surfaces (may affect adhesive strength).

3. Step-by-Step Installation

Step 1: Cut to Desired Length (If Needed)

• Only cut along the marked scissor lines (every 3 LEDs) on cuttable models.
• Do not cut randomly—this will damage the circuit and render the light bar inoperable.
• For IP-rated versions, seal the cut end with waterproof tape to prevent moisture intrusion.

Step 2: Prepare the Installation Surface

• Wipe the surface thoroughly with a clean, dry cloth to remove dust, oil, or debris.
• Let the surface dry completely before installation (ensure no residue remains).

Step 3: Mount the Light Bar

• Peel off the protective film from the 3M adhesive backing (avoid touching the adhesive with your fingers).
• Align the light bar with your desired position, press firmly along the entire length, and hold for 30 seconds to ensure full adhesion.
• For extra security (or uneven surfaces), attach the included mounting clips at 15–20cm intervals.

Step 4: Connect to Power Supply

• Match the positive (+) and negative (-) terminals of the light bar to the power supply (incorrect polarity will prevent operation).
• Ensure the connection is tight and secure—loose wires may cause flicker or short circuits.
• Plug the power supply into a standard outlet (check voltage compatibility: 12V/24V).

Step 5: Test & Adjust

• Turn on the power to test if the light bar works properly (check for uniform brightness and no flicker).
• Adjust the position if needed (reposition within 1 hour of installation for best adhesive performance).
• For dimmable/RGB models, pair with a compatible dimmer or smart controller (follow the controller’s user manual for setup).

4. Safety & Usage Tips

• Voltage Safety: Use only the recommended 12V/24V low-voltage power supply—do not connect directly to 110V/220V mains electricity.
• Waterproof Caution: Non-IP-rated models are for indoor dry use only; IP65/IP67 models are suitable for damp areas but not submersion.
• Heat Dissipation: Avoid covering the light bar with thick materials (e.g., fabrics, plastic) to prevent overheating.
• Installation Environment: Do not install in extreme temperatures (-10°C to 40°C is recommended).
• Children & Pets: Keep power supplies and wires out of reach of children and pets to avoid electric shock.

5. Troubleshooting

• No Light: Check polarity connection, power supply functionality, or if the cut end is damaged (re-seal if needed).
• Flickering: Ensure wires are tightly connected; replace the power supply if faulty.
• Adhesive Peeling: Clean the surface again (remove oil/residue) and reattach, or use mounting clips.
