There are some differences between COB tube lights and traditional LED tube lights in LED lighting fixtures, mainly reflected in the following aspects:

Light source structure:
The COB tube light (Chip on Board Cylinder Light) adopts COB technology, which integrates multiple LED chips on the same substrate to form a unified light source, making the light source more integrated and uniform.
Traditional LED tube lights typically use a single LED chip or multiple independent LED beads arranged together, with each LED emitting light independently and the light source relatively dispersed.

Lighting effect:
The light of COB tube lamp is relatively uniform, without obvious spots or light flowers, and the light is softer and more comfortable.
The light of traditional LED tube lights may exhibit point light source effect, resulting in uneven light spots, and it is necessary to improve the lighting effect through design such as reflectors.

Heat dissipation performance:
Due to the integration of LED chips on the same substrate, COB tube lights have a relatively uniform heat distribution and good heat dissipation performance.
In traditional LED tube lights, each LED bead is arranged independently, and the heat distribution may be uneven, requiring more complex heat dissipation design to ensure the stable operation of the LED.

Energy efficiency ratio:
Due to the high integration and uniformity of COB technology, COB tube lights typically have higher light efficiency and energy efficiency ratios.
Traditional LED tube lights may have slight differences in light efficiency and energy efficiency ratio, depending on the quality and design of the LED beads.
In summary, there are certain differences between COB tube lights and traditional LED tube lights in terms of light source structure, lighting effect, heat dissipation performance, and energy efficiency ratio. Consumers can choose suitable LED lighting products according to their actual needs and preferences.
