COB LED: The Ultimate Guide for Buyers in 2025
COB LED (Chip-on-Board LED) technology has revolutionized lighting solutions with its high efficiency, compact design, and superior brightness. Whether you're upgrading home lighting or sourcing for commercial projects, understanding COB LED can help you make informed decisions. Here’s a detailed breakdown of what buyers need to know in 2025.
How to Find Reliable COB LED from China in 2025
China remains a leading hub for COB LED manufacturing, but finding trustworthy suppliers requires due diligence. Look for certifications like CE, RoHS, and UL to ensure compliance with international standards. Platforms like Alibaba and Made-in-China list verified suppliers with customer reviews. Request samples to test performance before bulk orders.
What Buyers Should Know Before Buying COB LED from China
Price isn’t the only factor—consider lumen output, color temperature, and heat dissipation. Cheaper options may compromise on longevity. Ask for warranty terms and after-sales support. Shipping and customs duties can add costs, so clarify Incoterms (e.g., FOB or CIF) upfront.
Types of COB LED
1. Standard COB LEDs: Ideal for general lighting with uniform brightness.
2. High-Power COB LEDs: Used in industrial and outdoor settings for intense illumination.
3. Flexible COB Strips: Perfect for decorative and architectural lighting.
4. Tunable White COB LEDs: Adjust color temperature for ambient lighting needs.
Functions and Features of COB LED
COB LED packs multiple diodes on a single board, reducing energy consumption by up to 50% compared to traditional LEDs. Key features include:
- High CRI (90+): Renders colors more accurately.
- Low Glare: Even light distribution reduces eye strain.
- Thermal Management: Built-in heat sinks extend lifespan to 50,000+ hours.
Scenarios of COB LED
Home Lighting: Recessed downlights and track lighting.
Retail: Spotlighting products with vibrant clarity.
Streetlights: Energy-efficient municipal lighting.
Automotive: Headlights and interior ambiance.
How to Choose COB LED
1. Brightness: Match lumens to your space (e.g., 800 lm for a 10m² room).
2. Color Temperature: 2700K-3000K for warm light; 4000K-6500K for cool white.
3. Driver Compatibility: Ensure compatibility with existing dimmers or controllers.
4. IP Rating: IP65 for outdoor/damp environments.
COB LED Q & A
Q: How long do COB LEDs last?
A: Quality COB LED lasts 50,000–100,000 hours, reducing replacement costs.
Q: Are COB LEDs dimmable?
A: Yes, but check for compatible drivers (e.g., PWM or TRIAC).
Q: Can COB LEDs replace halogen bulbs?
A: Absolutely—they use 80% less energy and emit less heat.
Q: What’s the price range for COB LEDs?
A: $2–$20 per unit, depending on wattage and features.
Q: How do I prevent overheating?
A: Use aluminum PCBs or heat sinks for optimal thermal management.
