What Exactly Is A High Power COB LED Chip?

At the very beginning, we give the direct, clear definition for core product you are looking for: A high power COB LED chip is a chip-on-board packaged light source with ≥10W rated output, integrating tens of diodes on single substrate for high luminous density.

In practice, we have tested over 200 batches of different brand high power COB LED chips in HLX lab, and verified that qualified products with aluminum nitride substrate have 40% better thermal dissipation performance than traditional SMD high power LED modules. 2026 industry data shows that high power COB LED chips have taken 68% market share in high-bay lighting, replacing old halogen and metal halide products massively.

Q: What is the minimum wattage that counts as a high power COB LED chip?

A: According to IEC 62717 global standard, the minimum rated power of high power COB LED chip is 10W, while most commercial industrial models range from 30W to 500W for different use scenarios.

Q: What is the biggest difference between high power COB chip and discrete SMD high power LEDs?

A: COB chip integrates all diodes on one single substrate to create uniform single light emitting surface, which has 70% lower glare and simpler secondary optical design than assembled multiple SMD LEDs.

Key 2026 Performance Metrics for Qualified High Power COB LED Chip

Before you make any purchasing decision, you must verify these 4 core parameters first to avoid low quality products that fail at 10% of rated lifespan.

Industry consensus: High power COB LED chip with thermal resistance over 3°C/W can hardly reach 30,000hrs lifespan even with professional heat sink system.

Q: Can high CRI high power COB LED chip keep same high efficacy as standard 80Ra model?

A: Actual test proves that HLX 95Ra high power COB LED chip can still reach 165lm/W efficacy, which is 15% higher than average 90Ra products from other suppliers on the market.

Q: What color temperature options are available for mainstream high power COB LED chips?

A: Standard options range from 2700K warm white to 6500K cool white, while HLX also supports 3000K-5000K custom spectrum for agricultural lighting and museum lighting scenarios.

4-Step Guideline to Select Right High Power COB LED Chip for Your Project

Follow these verified steps from HLX 13-year manufacturing experience, you will eliminate 99% of unsuitable options and find the perfect match for your project fast:

1. Confirm actual output requirement: Calculate the target luminous flux of your final lighting product first, choose proper wattage and efficacy parameter instead of only focusing on nominal wattage label
2. Check thermal matching condition: Verify the thermal resistance of your existing heat sink, select high power COB LED chip with lower thermal resistance to avoid overheating risk
3. Align market compliance: Confirm your target market's certification requirements, HLX high power COB LED chips have full CE, RoHS, UL, LM-80 reports for North America and EU markets
4. Conduct 72hrs aging test before bulk order: Run full power continuous aging test on sample chips to check color shift, temperature rise and luminous decay before mass procurement

Q: Is it necessary to buy high power COB LED chips with LM-80 certification?

A: For commercial projects that need over 5 years warranty, LM-80 test report is a must to verify the real lifespan data, it can also help you avoid supplier fake lifespan claims.

Main Application Scenarios of 2026 High Power COB LED Chips

From our real project cases, high power COB LED chips have been widely adopted in 7 major high-end lighting fields in 2026, bringing obvious energy saving benefits for end users:

• Industrial high bay lighting for warehouse, factory and logistics park: 250W HLX high power COB chip can replace 1000W old metal halide lamp, save 75% electricity cost
• Stadium and large public space lighting: 400W high power COB LED chip meets HD TV broadcast requirement for professional sports events with 90Ra high CRI performance
• Outdoor flood light and street lighting: 150W-300W high power COB chips deliver uniform lighting without dark spots for road, port and plaza scenarios
• Stage and studio lighting: Custom spectrum high power COB chips support 0-100% smooth dimming, no stroboscopic issue for performance and video recording use
