In a COB light, you’ll have more diodes and a simpler circuit design that produces a compact light. On the other hand, a LED panel has fewer diodes and a more complex circuit design and looks like a collection of small lights. It can also be larger and heavier than a COB light.
The design and appearance aren’t the only differences. A COB light is more energy and heat efficient than an SMD light. It can produce more lumens with less energy, producing a brighter light (e.g., COB lights start at 80 lumens per watt, while SMD lights produce between 50 and 100 lumens per watt). However, it can’t create colored light, or color-changing effects like LED panels do. SMD lights are more versatile when it comes to color temperature.
You can use an SMD light as a point light because it illuminates evenly in all directions. However, because it emits a uniform beam of light, a COB light is better than a top light to illuminate the subject or a surface from above.
