What Is LED Strip Light? A Complete Guide for Specifiers

What Is LED Strip Light? Quick Answer: LED strip light is a flexible printed circuit board populated with surface-mount LEDs, used to create continuous linear illumination in coves, facades, retail, and signage. It operates on low-voltage DC (typically 12V or 24V) and is specified by CCT, CRI, lumen output, IP rating, and LED technology (COB or SMD). ## Introduction Architects, lighting designers, and procurement teams use LED strip as the backbone of concealed linear systems — not as a standalone fixture. Understanding strip construction, drive requirements, and environmental ratings prevents field failures on hotel, commercial, and outdoor programs. ## Definition An LED strip consists of: - Flexible PCB — copper traces and solder pads in a reel, typically 8–12 mm wide - LED emitters — SMD packages (2835, 5050, etc.) or COB chips bonded to the board - Circuit design — cut points, series/parallel groups, and current-limiting resistors or ICs - Protective coating — bare (IP20), silicone sleeve (IP65), or full extrusion (IP67/IP68) Power is supplied by an external LED driver converting mains AC to regulated DC. ## Technical Explanation ### COB vs SMD SMD strips place discrete LED packages at fixed pitch (e.g. every 8–10 mm). COB strips bond many chips under a phosphor layer for a continuous luminous line with minimal dot visibility at close range. ### Voltage 12V suits short decorative runs; 24V reduces current and voltage drop on longer hospitality coves (often 8–10 m per feed). Document max run length and wire gauge in the specification. ### Key metrics | Metric | What it means | |--------|----------------| | CCT | Correlated color temperature (2700K–6500K) | | CRI (Ra) | Color rendering; ≥90 typical for premium interiors | | W/m | Power density — affects brightness and thermal load | | IP | Ingress protection for wet or outdoor zones | | L70 | Hours to 70% lumen maintenance | ## Advantages - Flexible routing in coves, millwork, and curved architectural lines - Low voltage for safety vs line-voltage neon or cold cathode - Wide CCT/CRI and dimming protocol options (DALI, 0–10V) - Field-cuttable lengths at marked cut points (IP20/IP65 variants) - Scalable for OEM programs with stable BOM revision ## Disadvantages - Requires correct driver sizing and thermal path (aluminum profile recommended) - Visible diodes on SMD strips at close viewing distances without deep diffusers - IP67/IP68 versions cost more and may reduce delivered lumens vs bare strip - Poor terminations are the main field failure mode — not the LED itself ## Applications - Hospitality — guest room coves, corridors, lobby millwork - Commercial — retail window lines, mall circulation, facade accents - Architectural — podium outlines, canopy edges (often with neon flex or IP67 strip) - Signage — backlighting with diffusers ## How to Choose 1. Viewing distance — COB for <1.5 m; SMD acceptable with deep profile or greater distance 2. Environment — IP20 indoor dry; IP65 bathroom/covered outdoor; IP67+ exposed facade 3. Run length — prefer 24V for commercial lengths; request voltage-drop calculations 4. Dimming — match hotel BMS or control spec (DALI vs 0–10V) before locking SKU 5. Documentation — batch CCT, CRI, LM-80 or L70 data tied to exact BOM revision ### Q: Can LED strip be used outdoors? A: Yes, with IP67 or IP68 rated products and sealed connectors. Bare IP20 strip is indoor only. ### Q: How long does LED strip last? A: Quality strips are often rated 50,000 hours (L70). Life depends on drive current, heat management, and driver quality. ### Q: Can LED strip be cut on site? A: Most strips have marked cut points. Waterproof variants require re-sealing after cut — follow manufacturer termination instructions. ## Conclusion LED strip is a specification-driven component: technology (COB/SMD), electrical architecture, IP, and driver pairing must align with the installation detail. Export programs should request engineering support and sample approval before bulk production. ## About Mihoray Mihoray is a professional LED strip and neon flex manufacturer based in China, providing OEM and ODM lighting solutions for commercial, hospitality, architectural and landscape lighting projects worldwide.
