Know before you buy
This LED chip is compatible with a wide input voltage range of 9-50V. You will need a constant current LED driver that matches the specific wattage and voltage requirements of the chip you select.
Yes. Because this is a high-power COB LED, it generates heat during operation. To ensure the 10,000-hour lifespan and prevent damage, you must mount the chip onto an adequate aluminum heat sink or thermal management system.
Warm White provides a cozy, yellowish glow ideal for living areas, while White offers a crisp, clinical light suited for workspaces. Natural White sits in the middle, mimicking daylight for a balanced, neutral appearance.
Dimming capability depends entirely on the LED driver you pair with the chip. If you use a compatible dimmable constant current driver, you can adjust the brightness levels accordingly.
These COB LED chips feature a Color Rendering Index (CRI) of Ra>80. This indicates good color accuracy, making them suitable for most general indoor lighting applications.
While the aluminum housing is durable, these chips are not inherently waterproof or weather-sealed. If you plan to use them outdoors, they must be installed inside a properly rated, sealed lighting fixture.
