A COB light is a continuous light source. It is a type of LED light that you can place anywhere and have it illuminate the subject for hours. You can hold it or mount it on a light pole, keep it in the studio, or take it with you. A COB light allows you to change the direction and intensity of the light as you like and preserve the setup for a long time.

Constructively, a COB light is a panel of LED chips packed together very close. You can’t see any space between the LED chips since they are compact. As a result, a COB light produces a uniform and very bright beam of light. Don’t worry — you can dim the intensity of the light and use accessories to soften it. 

What Does COB Stand For?
COB is an acronym meaning Chip On Board. It describes the technology behind the COB lights, referring to the packed LED chips mounted in direct contact with silicon carbide or sapphire substrate. The COB technology provides a high density of LEDs on a small surface (e.g., there are 342 LEDs on a 10mm x 10mm surface).
