SMD2835 8mm 120LED 20m No-Voltage-Drop DC24V CRI90 LED Strip

COB 8mm 120LED RA90 LED Strip

This COB LED strip combines 120 LEDs per meter with 12W/m power output and RA90 color rendering. The 8mm PCB width fits standard commercial aluminum profiles for straightforward installation. 20-meter continuous run with no brightness loss.

This strip is ideal for:

• Commercial cove lighting, office ambient lighting, and general business environments
• Hotel corridors, lobbies, guest rooms, and cove lighting applications
• Aluminum profile installations, ceiling details, and architectural feature lighting
• Retail store displays, showroom lighting, and product highlighting applications

20-Meter No-Voltage-Drop Design

Standard LED strips suffer from voltage drop over long runs — the far end of a 5-meter strip is noticeably dimmer than the power-feed end. This constant-current design solves that problem by using special circuitry that maintains consistent brightness across the entire 20-meter length.

Why this matters for commercial projects:

• Single-end power feeding up to 20 meters (vs 5m standard)
• No dark spots or gradient dimming visible to end users
• Simplified wiring — fewer power feed points required
• Lower installation cost — fewer drivers and wire runs
• Cleaner appearance — uniform brightness for visible installations

For hotel corridors, long architectural coves, and commercial cove lighting where uniform brightness across long distances is critical, this is the only practical choice.

SMD Chip Technology Explained

This strip uses SMD2835 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

SMD2835 is the industry workhorse — the most widely used SMD chip type for commercial LED strips. It offers the best balance of brightness, efficiency, and cost, making it suitable for 70-80% of all LED strip 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 RA90: The high CRI rating produces natural color rendering suitable for hospitality, retail, and any space where appearance matters.

DC24V: Single voltage DC24V design optimized for specific applications.
