10W COB LED Chip for Professional Concentrated Lighting
The 10W COB LED chip with a 26mm diameter is the ideal component for building or repairing light fixtures with concentrated luminous flux and high efficiency. COB (Chip-on-Board) technology brings together multiple LED diodes on a single board, generating a uniform beam without blind spots. Suitable for DIY projects, replacing worn-out light sources in spotlights, light boxes, or technical lighting systems.
What you get with this product
- Luminous flux of 1150-1250 lm at only 10W consumed — efficiency of 140-150 lm/W, low consumption compared to equivalent conventional sources
- 19mm round chip with gel protective layer — homogeneous emitting surface, without unwanted spots or shadows in the beam
- Aluminum alloy heatsink base included — uniform thermal dissipation through the circular design with fins, extended chip lifespan
- Four contact points (2 positive, 2 negative) with clear marking — secure connection, no risk of polarity reversal
- Color temperature 6000-6500K (cool white) — clear light, suitable for display cases, illuminated signs, and technical lighting
- Color rendering index Ra over 80 — illuminated object colors are faithfully reproduced, without visible distortions
How it works and how to install
The 10W COB LED chip is powered by 30V DC via a suitable LED driver (300mA), which is not included in the package and must be purchased separately depending on the application. Mounting is done on the included heatsink surface with thermal paste (recommended, sold separately), applied between the back of the chip and the heatsink to ensure optimal thermal transfer. Electrical connections are made by soldering or clamps on the pads marked with plus and minus, strictly observing the polarity indicated on the base.
Frequently Asked Questions
Do I need a separate driver for this 10W COB LED chip?
Yes, the chip requires an LED driver that supplies 30V DC at 300mA. It does not power directly from 220V and does not include a driver in the package.
Is thermal paste mandatory for installation?
Yes, at 10W the chip generates significant heat. Without thermal paste between the chip and the heatsink, the temperature rises excessively and the lifespan decreases considerably.
Can this LED chip be used outdoors or in humid areas?
It is not recommended for humid environments or direct exposure to weather, as it does not have certified IP protection. Use is recommended exclusively indoors or in light fixtures with an adequate degree of protection.
