7W Cool White COB LED Chip for Lighting Projects
The 7W COB LED chip with an active diameter of 11mm is the compact solution for replacing or building lighting fixtures with low power consumption and high brightness. Mounted on a circular aluminum alloy base with a thickness of 1mm, it ensures the thermal dissipation necessary for stable long-term operation. Suitable for DIY applications, spotlight repairs, projectors, or custom LED lamps.
What you get with this product
- Concentrated brightness in a compact 11mm spot — ideal for narrow spotlights and accent lighting applications
- Aluminum alloy base included — uniform thermal dissipation without an additional radiator required in low-power applications
- Protective gel applied over the LED die — protects the chip against moisture and minor mechanical shocks
- Four power contact points (2+ / 2-) — secure and flexible connection in any mounting
- Consumption of only 7W at 300mA — replaces conventional sources up to 50W with a fraction of the energy consumed
- Standardized 20mm format — compatible with most sockets and heat sinks for general-purpose COB chips
How it works and how to install
The 7W COB LED chip operates by direct current power at 21V-23V DC and a current of 300mA, requiring an LED driver compatible with these parameters. Installation consists of thermally bonding the aluminum base to a suitable heat sink and connecting the wires to the four power pins, observing the polarity marked on the board. No special tools are needed — a soldering iron and thermal paste are sufficient for proper assembly.
Frequently Asked Questions
Do I need a separate driver for this LED chip?
Yes, the chip requires an LED driver with an output of 21V-23V DC at 300mA. It cannot be connected directly to the mains without a driver.
Is a heat sink necessary for cooling?
At 7W, a small aluminum heat sink attached under the included base is recommended to extend the chip's lifespan, especially in continuous operation.
What is the color temperature of the Cool White variant?
The Cool White variant corresponds to a color temperature of approximately 6000K-6500K, producing a white light with a bluish tint, suitable for functional and task lighting.

Inspired to create a chair where the backrest and armrests are molded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.
