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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between Cool White and Warm White color temperatures?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What driver voltage and current do I need for the different wattages?\u003c\/h4\u003e\n\u003cp\u003eA: 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.
