5W Cool White COB LED Chip for Lighting Projects
The 5W COB LED chip with a color temperature of 6500K offers clear cool white light, suitable for floodlights, DIY spotlights, and technical lighting applications. With a luminous flux of 600 lumens at only 5W consumed, this COB module represents a compact and efficient light source for building or replacing existing light sources. The aluminum alloy backing ensures heat dissipation directly from the source, extending the chip's lifespan.
What you get with this product
- 600 lumens from a module of only 20mm diameter — high light density in a minimal space
- Cool white light at 6500K, ideal for functional lighting, workshops, display cases, or floodlights
- Integrated aluminum alloy backing — uniform cooling without large additional heat sinks
- Four clearly marked power contacts (2+ and 2-) — simple connection, no risk of accidental reversal
- 11mm COB die covered with a protective gel layer — increased mechanical resistance during mounting
- Compatible with standard 15-17V DC drivers, easy to integrate into new projects or repairs
How it works and how to install
The 5W COB LED chip is powered directly by a DC driver with a voltage between 15V and 17V at a current of 300mA. Mounting is done by thermal or mechanical attachment of the aluminum backing to an appropriate heat sink, followed by connecting the four power contacts to the driver. No special processing is required — the compact 20mm size and clear polarity markings make integration quick even for DIY projects.
Frequently Asked Questions
What driver can I use for this 5W COB LED chip?
A DC driver with an output voltage of 15-17V and a current of 300mA is required. Constant current drivers with these parameters are most suitable for stable operation.
Do I need a separate heat sink for this chip?
The integrated aluminum backing helps dissipate heat, but for continuous operation at maximum power, it is recommended to attach it to an additional heat sink to keep the junction temperature within safe limits.
What is the difference between the 11mm diameter and the 20mm size?
The 11mm diameter represents the active area of the COB die that emits light, and 20mm is the total size of the aluminum backing on which the chip is mounted.
