20W COB LED Chip for Compact Professional Lighting
The 20W COB LED chip, measuring 13.5 x 13.5 mm, delivers a concentrated luminous flux of 1300-1400 lm in an extremely compact format, ideal for technical lighting projects and industrial applications. The integrated aluminum heat sink with mounting slots ensures uniform thermal dissipation, extending the chip's lifespan. Suitable for light fixtures, advertising signs, and custom lighting systems.
What you get with this product
- High luminous flux of 1300-1400 lm at 20W consumption — efficiency up to 150 lm/W, more light for the same energy consumed
- Miniaturized format of 13.5 x 13.5 mm — easily integrates into compact light fixtures or projects with limited space
- 9mm LED die protected with gel — active surface resistant to minor mechanical shocks and oxidation
- Aluminum heat sink with mounting slots — stable attachment to the radiator and optimal thermal transfer without premature overheating
- 6000-6500K cool white color temperature — clear, high-contrast light, recommended for advertisements, display cases, and technical lighting
- Lifespan of approximately 20,000 hours — infrequent replacements and reduced long-term maintenance costs
How it works and how to install it
The 20W COB LED chip is powered by 30V DC with a current of 300 mA via a compatible LED driver, connected to the two contacts marked plus and minus in the corners of the aluminum heat sink. Mounting on an aluminum radiator with thermal paste is mandatory to prevent overheating — without a suitable radiator, the chip's lifespan decreases significantly. The installation process is simple for anyone with basic experience in electronics or LED lighting.
Frequently Asked Questions
Do I need a separate driver for this 20W COB LED chip?
Yes, the chip requires an LED driver that supplies 30V DC at 300 mA. It does not connect directly to the 220V mains.
Is mounting on a radiator with thermal paste mandatory?
Yes, it is mandatory. At 20W, the chip generates significant heat — without a radiator and thermal paste, you risk rapid damage or burning.
What is the Color Rendering Index (CRI/Ra) of this LED chip?
The chip has an Ra greater than 80, which means accurate color rendering, suitable for display cases, advertisements, and commercial lighting.
