15W COB LED Chip for Professional Lighting and DIY Projects
The 15W COB LED chip with a 13.5mm aluminum substrate is chosen by lighting fixture manufacturers and electronics enthusiasts for its high light density and proven energy efficiency. COB technology combines multiple emission points into a single chip, providing a uniform luminous flux of up to 2050 lumens at only 15W consumption. Suitable for lighting fixtures, lightboxes, backlit advertisements, and custom lighting systems.
What you get with this product
- Luminous flux of 1950-2050 lm at 15W — equivalent to a conventional bulb over 100W, with low consumption
- Efficiency of 140-150 lm/W — more light for the same consumption, lower operating costs in the long run
- Square aluminum substrate with mounting slots — uniform thermal dissipation, secure mounting on a heatsink
- Round 9mm chip with gel protection — mechanically protected emission surface and reduced moisture ingress
- Color Rendering Index Ra over 80 — colors appear natural, suitable for showcases, advertisements, and accent lighting
- Lifespan of up to 20,000 hours — infrequent replacements, reduced maintenance in permanent installations
How it works and how to install it
The 15W COB LED chip is powered at 45V DC with a current of 300mA, so it requires a compatible LED driver — it does not connect directly to the mains. Mounting is done on an aluminum heatsink with thermal conductive paste applied between the chip and the heatsink surface, to efficiently dissipate the heat generated at high power. The two power contacts are positioned in diagonal corners, marked with plus and minus, and are soldered or connected via clips according to the indicated polarity.
Frequently Asked Questions
What LED driver is compatible with this 15W chip?
A driver with a 45V DC output and a constant current of 300mA is required. Choose an LED driver sized for a minimum of 15W at these values for stable operation.
Does it absolutely need a heatsink, or can it be used without one?
A heatsink is mandatory. At 15W, the chip generates significant heat that can damage it in a few minutes without proper thermal dissipation. Thermal conductive paste between the chip and the heatsink is also necessary.
Can this LED chip be used outdoors or in humid environments?
It is not recommended for direct exposure to moisture or excessive heat. For outdoor applications, the chip must be integrated into a lighting fixture with adequate IP protection.
