Product Features & Advantages
Detailed technical advantages and real-world benefits for your project.
Free-Cut COB Strip — Cut Anywhere Every 2.5mm
This Free-Cut COB strip uses a parallel circuit design allowing cuts every 2.5mm — between any two LEDs — with zero wasted LEDs. Ideal for custom-length installations, irregular architectural features, and precision projects where every millimeter matters. Museum-grade color accuracy with CRI RA98.
This strip is ideal for:
- Retail store displays, showroom lighting, and product highlighting applications
- Hotel corridors, lobbies, guest rooms, and cove lighting applications
- Commercial cove lighting, office ambient lighting, and general business environments
- Kitchen cabinets, display cases, furniture accent lighting, and under-shelf illumination
CRI RA98 — Ultra-High Color Rendering
This strip delivers CRI RA98 — one of the highest color rendering ratings commercially available for LED strips. The rating measures how accurately colors appear under the light compared to natural daylight, with RA100 being a perfect match.
Why CRI RA98 matters in practice:
- Museums and art galleries — artwork appears with true colors and subtle details
- Fashion retail — fabric colors appear authentic, reducing customer returns
- Jewelry and watches — metallic finishes and gemstones show their true brilliance
- Food display — meat, produce, and prepared food look natural and appetizing
- Photography and broadcast studios — accurate color reproduction for professional work
- Dental and medical clinics — accurate assessment of skin tones and tissue
Black PCB enhancement: This version features a black PCB substrate that absorbs stray light and enhances the visual contrast of the LED output. Ideal for installations where the strip itself is visible, and for applications where color contrast is critical.
SMD Chip Technology Explained
This strip uses SMD4040 LED chips. SMD stands for Surface-Mount Device, which means the LEDs are mounted directly onto the PCB surface using automated pick-and-place equipment. Different SMD sizes offer different characteristics:
| Chip Type | Size | Best For |
|---|---|---|
| SMD2835 | 2.8×3.5mm | General purpose, cost-effective |
| SMD3535 | 3.5×3.5mm | Higher power, better heat management |
| SMD4040 | 4.0×4.0mm | Premium applications, highest output per chip |
| SMD5050 | 5.0×5.0mm | RGB and tri-color applications |
SMD4040 chips are premium-grade with the highest output per individual chip. The larger size provides better heat dissipation and supports higher CRI ratings. SMD4040 is typically used in flagship products for demanding applications.
Technical Specifications Explained
Lumen Output (1260 lm/m): At 12W/m, this strip delivers approximately 1260 lumens per meter — appropriate for general ambient lighting.
CRI RA98: The ultra-high CRI rating means colors appear virtually identical to natural daylight — essential for premium retail, museums, medical, and photography applications.
DC24V: Single voltage DC24V design optimized for specific applications.
Honest Positioning in Our SMD Range
| Model Type | Power | Best For |
|---|---|---|
| SMD2835 Standard (180-240 LED/m) | 12-18 W/m | General commercial use |
| SMD2835 Multi-row (2-3 rows) | 18-28 W/m | High-output commercial |
| SMD2835 20m Constant Current | 12 W/m | Long continuous runs |
| SMD3535/4040 Premium (RA98) | 12-18 W/m | Premium retail, museums |
| SMD2835 Waterproof (IP65/68) | 8-14 W/m | Outdoor and wet areas |
| SMD2835 AC Driver-Free | 7-14 W/m | Long runs, retrofits |
This product positioning: Premium — High-end specification for quality-sensitive projects.
Installation Best Practices
- Aluminum profile recommended for runs over 2 meters
- Match driver at 1.2× load — provides safety margin
- Use DC24V for runs over 3 meters (reduced voltage drop)
- Clean surface before applying 3M VHB adhesive backing
Packaging and Shipping
- Reel length: 10M per reel
- Master carton: 500 meters per carton
- Container capacity: approximately 55,000-60,000 meters per 20ft container

Frequently Asked Questions
Common questions from importers, wholesalers, and project contractors about this product.
Standard MOQ is 3,000 meters per CCT (e.g., 3,000m of 3000K). For OEM orders with custom branding and packaging, MOQ is 5,000 meters per specification. Mixed color temperatures within the same order are welcome as long as each CCT meets MOQ.
Standard orders ship within 20–25 working days from order confirmation and deposit receipt. Custom OEM orders with special branding and packaging require 30–35 days. Exact delivery dates are confirmed before production starts.
Yes. We offer 1–2 meter evaluation samples — buyer covers the shipping cost only. For finished product samples with packaging, approximately USD 15 applies. All sample fees are fully refunded when a bulk order is placed.
Standard LED strips can only be cut at designated points every 25mm or 50mm. This Free-Cut version uses a parallel circuit design allowing you to cut every 2.5mm — between any two LEDs — with both sides continuing to light normally. This is ideal for custom-length installations where every millimeter matters: custom cabinets, irregular architectural features, and signage projects.
Yes. We offer full OEM services including logo printing on the PCB, custom packaging design, private labeling, retail-ready box packaging, custom barcode, and multi-language instruction cards. OEM MOQ starts at 5,000 meters per specification.
All products come with CE and RoHS certification as standard. FCC certification is available for North American markets. ISO 9001 quality management certification applies to our entire factory. Full certificate documentation is provided for customs clearance.
