Cob led 200w

When evaluating a 200W COB (Chip on Board) LED, you must focus on Luminous Efficacy, which should ideally be above 130 lm/W to ensure energy efficiency. The Color Rendering Index (CRI) is critical; for general lighting, a CRI > 80 is standard, but for photography or high-end retail, look for CRI > 95 (R9 > 90). Additionally, verify the Thermal Resistance of the substrate—ceramic substrates offer better heat dissipation than aluminum, significantly extending the chip's lifespan beyond 50,000 hours.

For global trade, ensure the product carries CE, RoHS, and FCC certifications. If you are exporting to the North American market, UL or ETL listing is essential for insurance and building code compliance. Furthermore, request an LM-80 test report, which provides standardized data on lumen maintenance and color shift over time, ensuring the product won't degrade prematurely after installation.

A 200W COB generates significant concentrated heat. You must ensure the supplier provides or recommends a high-performance heat sink, typically made of 6063 extruded aluminum or featuring heat pipe technology. The junction temperature must be kept below 85°C to prevent light decay. For industrial applications, consider active cooling (fans) or liquid cooling systems to maintain stability in high-ambient-temperature environments.

Due to its high intensity and single-point light source characteristics, the 200W COB is ideal for High Bay lighting in warehouses, Stadium floodlights, and Stage lighting (PAR lights). It is also widely used in Film and Photography lighting because it produces a soft, uniform beam without the 'multi-shadow' effect common in SMD LED arrays.

It is common for low-tier suppliers to drive a 150W chip at higher currents to claim 200W, which leads to rapid burnout. Always request a sample and conduct a Integrating Sphere test to verify actual power consumption and luminous flux.

Focus your negotiation on the brand of the LED flip-chip (e.g., Bridgelux, Citizen, or high-quality domestic brands like San'an) and the warranty period. A professional supplier should offer a 3 to 5-year warranty. For bulk orders exceeding 500 units, aim for a 10-15% volume discount, and negotiate for 2% spare parts (drivers and chips) to be included free of charge to cover potential field failures.

COB LEDs are sensitive to Electrostatic Discharge (ESD) and physical pressure on the silicone resin. Ensure the supplier uses Anti-static tray packaging and vacuum-sealed moisture-proof bags. For international shipping, specify double-walled corrugated boxes with internal foam bracing. If shipping to the US or EU, ensure the HS Code (typically 8541.41) is correctly declared to avoid customs delays or incorrect tariff applications.

Prioritize Audited Suppliers who have undergone on-site verification by inspection companies like SGS or TÜV Rheinland. Check their Trust Points and look for a history of exporting to your target region. A reliable supplier will be transparent about their production capacity and provide ISO 9001 factory audit reports upon request.
