Why Choose This COB LED Chip?
- No Driver Needed: Built-in smart IC technology allows direct connection to AC 110V or 220V — simplifying your build and reducing component costs.
- High Efficiency: COB (Chip-on-Board) technology concentrates multiple LED elements into a single module, delivering superior brightness and energy savings over traditional bulbs.
- Full Spectrum Option: The full spectrum variant (380–780nm) covers the complete visible light range — ideal for plant grow lighting, including seedling, vegetative, and flowering stages.
- Versatile Applications: Perfect for DIY spotlights, floodlights, grow tents, grow boxes, hydroponic systems, bonsai gardens, outdoor garden lighting, and more.
- Wide Compatibility: Works with both 110V (North American standard) and 220V (European/international standard) power systems.
- Durable Construction: Aluminum body ensures structural stability and efficient thermal transfer when paired with a heatsink.
Important Safety Note
⚠ Heat Sink Required: This COB chip generates significant heat during operation. Always mount it on an adequate aluminum heatsink before powering on. Operating without a heatsink will damage the chip and may create a safety hazard.

Frequently Asked Questions
Q: Does this COB LED chip require an external driver or ballast?
A: No — this chip features a built-in smart IC that allows it to operate directly from AC 110V or 220V mains power without any external LED driver. This makes it an excellent choice for straightforward DIY lighting builds.
Q: What heatsink do I need for this COB LED chip?
A: You must use an aluminum heatsink appropriately rated for the wattage you choose (50W, 70W, or 100W). The chip should never be powered on without a heatsink attached, as excess heat will damage the chip. For 100W operation, a large aluminum heatsink with active cooling (a fan) is recommended.
Q: Can I use this COB LED chip as a grow light for plants?
A: Yes — the full spectrum option covers 380–780nm, which encompasses the wavelengths most beneficial for plant growth, flowering, and fruiting. It is well-suited for small grow boxes, grow tents, hydroponic systems, and bonsai plants.
Q: What wattage option should I choose?
A: The 50W chip is suitable for smaller applications or where space is limited. The 70W is a great mid-range choice for medium-sized DIY floodlights. The 100W chip delivers the most brightness and is ideal for large grow areas or high-output floodlight projects.
