Advantages and disadvantages of COB lights
Advantages of COB lights:

1. High light efficiency. The light efficiency of the COB lamp is about 30% higher than that of the LED lamp, so at the same power, the brightness of the COB lamp is higher.

2. Uniform light color. Because the COB lamp packages multiple LED chips on the same substrate, the light color is more uniform.

3. Energy saving and environmental protection. COB lamp has higher light efficiency and can achieve higher energy saving effect. At the same time, because the production process of COB lamp does not need to use harmful substances such as mercury, it is more environmentally friendly during use.

Disadvantages of COB lamp:

1. The price is higher. Because the production process of COB lamps is more complex, the price is relatively high.

2. High heat. Because the COB lamp will generate a large amount of heat during the working process, it needs to be heat dissipated.

Advantages and disadvantages of LED lights
Advantages of LED lights:

1. Long life. The life of LED lights can reach more than 50,000 hours, which is longer than the life of traditional bulbs.

2. High light efficiency. Although the light efficiency of LED lamps is lower than that of COB lamps, the light efficiency of LED lamps is still higher than that of traditional light bulbs and fluorescent lamps.

3. Light color saturation. The light color of LED lamps is more saturated than traditional light bulbs and fluorescent lamps, and can show more realistic colors.

Disadvantages of LED lights:

1. Low light efficiency. Compared to COB lights, LED lights have lower light efficiency.

2. Uneven light color. Since the LED lamp bead has only one PN junction, the light color is not as uniform as the COB lamp.
