Description: 10pcs round COB 3W high power LED chip bulb lamp light in Warm White, Natural White, and White. COB LED offers excellent thermal performance, long lifespan, and low power loss. Heat dissipation is efficient and easy to manage, generating only about 30% of the heat compared to standard high power LEDs. Among various LED types such as high power LED, SMD, and DIP, COB LED provides superior thermal resistance and cooling performance. The lighting effect is smooth, with no dizziness, no uncomfortable glare, and no zebra patterns. When lit, it appears uniform, similar to a continuous lighting panel.
