⚠️ Important Note
A heat sink (aluminum heatsink) is required for proper operation. Do NOT power on the LED chip without an adequate heatsink attached — operating without one will damage the chip and void its usability.

Frequently Asked Questions
Q: What wattages are available for these LED COB chips?
A: These LED COB chips are available in five wattage options: 10W, 20W, 30W, 50W, and 100W, making them versatile for a wide range of DIY lighting applications from compact spotlights to large flood lights.
Q: Do I need a heat sink to use these LED COB chips?
A: Yes, an aluminum heat sink is absolutely required. High-power LED COB chips generate significant heat during operation, and running them without a properly sized heatsink will cause irreversible damage. Always mount the chip securely on an appropriate aluminum heatsink before powering it on.
Q: What is the difference between Cool White and Warm White color temperatures?
A: Warm White (2800K–3500K) produces a soft, golden light similar to traditional incandescent bulbs — ideal for cozy, ambient environments. Cool White (6000K–6500K) emits a crisp, bright daylight-style light that's great for workspaces, gardens, security lighting, and anywhere you need maximum visibility.
Q: What driver voltage and current do I need for the different wattages?
A: The 10W chip requires a driver voltage of 9–12V with a forward current of 850–900mA. The 20W, 30W, 50W, and 100W chips all operate at 30–36V, with forward currents of 600mA, 900mA, 1500mA, and 3000mA respectively. Always use a compatible constant-current LED driver for best results.
