7W 26mm COB LED Chip for Lighting Projects
The professional 7W COB LED chip with a 26mm diameter is a compact and efficient light source, suitable for light fixtures, spot lighting systems, or illuminated advertising signs. COB (Chip-on-Board) technology ensures a uniform luminous flux of up to 810 lm, with an efficiency of 140-150 lm/W, at a cool white color temperature of 6000-6500K.
What you get with this product
- Uniform illumination without dark spots — the 19mm COB chip with protective gel distributes light evenly across the active surface
- High efficiency of up to 150 lm/W — you consume 7W and get up to 810 lumens, reducing energy costs in continuous applications
- Integrated aluminum alloy thermal support — dissipates heat efficiently through radial fins, extending the chip's lifespan
- Compatible with a wide range of projects — suitable for DIY light fixtures, spot systems, advertising signs, and electronic prototypes
- Color rendering index Ra over 80 — illuminated objects' colors are rendered naturally and faithfully
- Simple connection with four clear contacts — two positive and two negative, marked on the support, with no risk of confusion
How it works and how to install it
The 7W COB LED chip is powered directly at 21V DC with a current of 300mA via a compatible LED driver, connecting the correctly marked poles on the aluminum support. Mounting is done by adhering the chip to an additional heat sink or a metal surface with thermal paste, which is mandatory for dissipating the heat generated at high power. It should not be connected directly to the mains without a driver and should not be exposed to humidity or excessive heat sources.
Frequently Asked Questions
What driver do I need for this 7W COB LED chip?
An LED driver with a 21V DC output and a constant current of 300mA is required, dimensioned for a power of at least 7W.
Does the chip absolutely need a heat sink or can it run without one?
Yes, a heat sink and thermal paste are mandatory. At 7W, the chip generates significant heat which, without proper dissipation, reduces its lifespan or can damage the component.
Can this COB LED be used outdoors or in humid environments?
No. The chip does not have declared IP protection and is not recommended for humid environments or direct exposure to weather without an additional sealed enclosure.
