Can I cut this strip to a custom length?

Yes, absolutely. The strip is designed to be cut every 3 LEDs, which corresponds to every 31.25mm (about 1.23 inches), at the clearly marked copper pads.

Why is a high CRI important?

A high Color Rendering Index (CRI) of 90+ ensures that the light shows colors more accurately and naturally, almost like sunlight. This is essential for settings like retail stores, art galleries, kitchens, or anywhere true color representation matters.

Ideal for Precision Lighting Applications

Architectural Accents & Cove Lighting The ultra-slim 3.5mm profile allows this strip to be seamlessly integrated into tight architectural reveals, narrow coves, and minimalist designs. Use it for edge-lit signs, under-shelf lighting, and creating subtle glows where larger strips won't fit.

DIY & Hobbyist Projects An excellent choice for model makers, custom PC builders, and creative enthusiasts. Its miniature size and flexibility make it easy to incorporate detailed lighting into dioramas, scale models, and unique electronic projects.

How to Install & Use This LED Strip

Ensure the installation surface is clean, dry, and free of dust or oils.
Measure the required length and carefully cut the strip along the designated copper cut marks.
Connect the strip to a compatible DC12V power supply. For dimming, connect it through a controller from our Single Color Dimmer Series.
For IP20 and IP67 versions, peel the adhesive backing and firmly press the strip onto the surface.
Connect the power supply to your power source to light up the strip.

⚠ Precautions

Always use a regulated DC12V power supply. Using a higher voltage will destroy the strip. We recommend a power supply with at least 20% higher capacity than the strip's total power requirement. How to choose led strip light power supply?

Frequently Asked Questions

Q: What makes this LED strip 'super narrow'?

A:Its Printed Circuit Board (PCB) is only 3.5mm wide, which is significantly thinner than standard 8mm or 10mm strips. This allows it to be installed in very tight grooves, channels, and intricate designs.

Q: What do I need to power a full 16.4ft roll?

A:You will need a DC12V power supply. The full roll consumes 40 watts (8W/m x 5m), so we recommend a power supply with a capacity of at least 48 watts to ensure stable performance.

Q: What is the difference between the two IP67 waterproof options?

A:Both offer excellent protection against water and dust. The Transparent Heat Shrink Tube is a slimmer profile, while the Outdoor Silicone Tube is slightly more robust and includes a 3M adhesive backing for easier installation.

Q: How do I dim this LED strip?

A:This strip is fully dimmable from 0-100%. To control the brightness, you will need to connect it to a compatible single-color LED dimmer or controller between the strip and the power supply.
