Advantage:
1. Large power range, there are low-power products such as 3W and 5W to meet the needs of restaurants and home spaces; there are also larger-power products such as 25 and 35W to meet the lighting needs of stores;
2. The color temperature range is wide, from 2400K, 2700K to 5000K, 6000K. The color temperature is diverse and customizable, breaking the color temperature limitations of metal halide lamps such as 3000K and 4000K, and meeting the needs of more subdivided fields;Color rendering has also been improved.
Shortcoming:
1. COB light source products are difficult to achieve ultra-narrow viewing angles. Because of its large luminous surface, it is difficult to focus the light. Generally speaking, the small viewing angle that COB type track spotlight manufacturers can do is about 10° (except for single museum-grade products)
The light spot of COB light source products is prone to secondary spots, and the spot cutoff line is relatively healthy. (Of course, special optical processing, such as adding an optimizer, can also be used to eliminate secondary spots)
