The table below shows you that besides the cost, COB LED tends to win over other grow light types in every criterium. Let's blast through the details.

Light Intensity
This is the number one factor that affects your plant growth, especially flowering plants. Regarding this, COB LED is only behind HPS. It has a stronger light output than traditional LED grow lights and other light types.

Light Spectrum
All modern LED grow lights, including COB LEDs, are known for their widest spectrum wavelengths. Some bulbs also include 12-color spectrum colors, including IR (infrared ray) and UR (ultraviolet ray)

Heat Output
Heat ventilation is also a strong point of COB LED. Modern technology allows these LEDs to produce strong light output while controlling the heat emitted. Some high-end COBs also use quality substrate, drivers, fans, which control the heat to the minimum.

Size
Though COB LEDs with more power will be bigger, you'll never have such a compact light that still generate lots of light like COB, which makes it better suited for small areas.

Lifespan
Depending on the COB material build, most COBs can last from 30,000 - 60,000 hours. This is several times higher than other grow light types.
