3W COB LED Chip for Precise Lighting Projects
The professional 3W COB LED, measuring 13.5 x 13.5 mm, is a compact and efficient light source, ideal for integration into light fixtures, illuminated signs, and customized lighting systems. COB (Chip on Board) technology ensures a uniform luminous flux of 400-450 lm from a small surface, without visible light spots. The aluminum base with mounting slots facilitates heat dissipation and stable attachment to a heatsink.
What you get with this product
- High luminous flux for its small size — 400-450 lm from a 13.5 mm chip, suitable for applications where space is limited
- Uniform cool white light — 6000-6500K color temperature without spots or unevenness, thanks to the COB construction with protective gel
- Integrated aluminum base with mounting slots — quick attachment to standard heatsinks, without additional modifications
- Lifespan of approximately 20,000 hours — rare replacements and reduced long-term maintenance costs
- Two clear polarity contacts marked in opposite corners — quick and secure connection, without risk of accidental reversal
- Compatible with multiple projects — light fixtures, advertising light boxes, DIY systems, or chip replacement in existing equipment
How it works and how to install it
The 3W COB LED is powered by 9V DC with a current of 300mA, requiring a suitable constant voltage driver or power supply. Installation is done by soldering with thermal paste onto an aluminum heatsink to ensure proper dissipation of the heat generated during operation. The positive and negative power contacts are positioned in the diagonal corners of the square base and can be soldered or connected with appropriate clamps.
Frequently Asked Questions
What driver or power supply should I use for this 3W COB LED?
A constant current source or an LED driver providing 9V DC at 300mA is required. Do not connect directly to the mains or to variable voltage sources.
Does it necessarily need a heatsink or can it operate without one?
Yes, mounting on a heatsink with thermal paste is mandatory. Without adequate heat dissipation, the chip will quickly overheat and its lifespan will significantly decrease.
Can this LED chip be used in wet areas or outdoors?
It is not recommended for wet environments or direct exposure to weather, as the chip does not have an IP protection rating. Use it only inside properly sealed light fixtures.
