50W COB LED Chip for Professional High-Density Lighting
The 50W COB LED chip with an active diameter of 14.8mm offers a concentrated luminous flux of up to 6340 lumens, ideal for light fixtures, projection systems, and lightboxes. COB (Chip on Board) technology ensures uniform light distribution without dark spots, in a compact 19x19mm format mounted on an aluminum substrate for efficient thermal dissipation.
What you get with this product
- High luminous flux of 6240-6340 lm from a compact chip — real lighting power for demanding projects
- Luminous efficacy of 140-150 lm/W — low consumption relative to the brightness achieved
- Aluminum substrate with integrated mounting slots — quick installation on a heatsink without additional modifications
- Round chip covered with protective gel — chip protected from minor mechanical shocks and contamination
- Two clear contacts marked + and - in opposite corners — easily identifiable polarity, secure connection
- Compatible with a wide range of applications — light fixtures, illuminated signs, projectors, and custom LED systems
How it works and how to install
The COB LED chip is powered by 36V DC via a compatible 50W LED driver, connected to the two marked contacts in the corners of the aluminum plate. Mounting on an appropriate heatsink is mandatory, with thermal paste applied between the chip and the heatsink surface, to prevent overheating. Installation is accessible to any electrician or lighting fixture builder with basic knowledge of LED electronics.
Frequently Asked Questions
Which LED driver is compatible with this 50W chip?
An LED driver with a 36V DC output and a current of 1200mA (1.2A) is required. Choose a driver with a nominal power of at least 50W for stable operation.
Can it be used without a heatsink?
No. This chip reaches high temperatures during operation and absolutely requires mounting on a heatsink with thermal paste — lack of cooling will irreversibly damage the chip in a short time.
Is the color temperature also available in warm white?
The described variant is cool white, 6000-6500K. Check the other available options in the store for different color temperatures.
