All LED lighting is made up of a light package in one form or other. A COB or ‘chips on board’ light is a type of led package.

In COB lighting, single LED chips are placed directly on a circuit board (or substrate) which has thermal properties to disperse heat. Heat dissipation is a very important aspect of LED lighting because it can have a major impact on the life expectancy of the luminaire. Traditional LED chips are not placed directly on the substrate and therefore there is greater thermal resistance. As a result of improved heat dissipation, COB lights can have a higher LED chip density and therefore achieve higher light levels while maintaining or improving life expectancy. COB downlights and spotlights are characterised by the yellow chip (package) visible inside the reflector. Sometimes a diffuser or cover is placed on the light to hide the COB chip.

In Summary: COB lights are a more efficient form of LED lighting for general lighting applications because:

The light has a more uniform appearance
Better life expectancy
Can achieve higher light levels over a larger area
They are more stable and reliable than standard LED packages
