Frequently Asked Questions
Q: What wattages are available for this LED COB chip?
A: The LDHLM LED COB chip is available in six power ratings: 10W, 20W, 40W, 50W, 60W, and 70W. Each wattage has a corresponding forward current (e.g., 300mA for 10W up to 2100mA for 70W), so you can choose the right chip for your specific DIY spotlight, floodlight, or ceiling light project.
Q: What color temperatures are available?
A: These COB LED chips are available in two color temperatures: Warm White (3000–3200K) for a cozy, ambient glow, and Cool White (6000–6500K) for a bright, daylight-style output — perfect for task lighting, outdoor floodlights, or commercial applications.
Q: Are these LED COB chips compatible with standard AC power?
A: Yes. These chips are designed to operate on AC 220–240V power supplies. However, as bare COB lamp beads, they require a compatible LED driver to regulate the forward current — ensure you pair them with the correct driver for your chosen wattage for safe and optimal performance.
Q: What certifications do these LED chips carry?
A: The LDHLM LED COB chips are certified to CCC, CE, FCC, PSE, and RoHS standards, confirming they meet safety and environmental compliance requirements across multiple markets.
