What are COB LEDs(Including COB LEDs and Flip Chip COB LEDs--4046, 2828, 1414/1313 etc.)? Relatively new to the LED market, chip on board (COB) LEDs offer many advantages over the standard options. COB LEDs are basically multiple LED chips (typically nine or more) bonded directly to a substrate by the manufacturer to form a single module.

Advantages of COB LEDs:

COB lights have a few obvious advantages that will tell you exactly which photo setup they fit.

Firstly, they are reliable, affordable, and practical. In addition, they are relatively small compared to older studio lights, making them easier to carry around.

Next, COB lights provide bright light without emitting too much heat. And although the heat may not bother you, it definitely bothers the subject, especially if you photograph people wearing makeup, small children, animals, or heat-sensitive subjects (e.g., ice cream).

Another advantage of COB lights is the uniform lighting effect. They provide a powerful and consistent flow of light, able to illuminate large spaces, and cover multiple subjects. Furthermore, they don't produce the multiple shadow effect you can expect with other types of LED lights.

Like with all continuous lighting systems, you get to see the effect of light before taking the photo. You'll be able to see exactly how much of the scene is illuminated, how the light falls on each element in the frame, and what adjustments are required.

Technology advancements in lighting, especially LED, are creating tremendous opportunities in the field of light. Lighting solutions today not only need to work and to last, they need to give customers a competitive edge.
