LED light engine manufacturers push for greater consistency
- Details
The industry is concerned with a more complete testing of the performance of light engines. Composed of the combination of one or more LED modules, together with an LED driver (also known as electronic control gear, or ECG), the variations in light engine output account for most of the variations in LED colour temperature, brightness and other output characteristics.
To alleviate this problem, many LED light engine manufacturers provide 100 percent "functional testing" of lamps along with first article and periodic inspections of a production run. However, functional testing merely validates that the lamps will illuminate, and usually don't analyze the CCT (correlated colour
