LED Tester can be seperated by the LED measurement targets.

On the one hand you can test LEDs eletrical to find out if the LED is working on a circuit board. This simple method can be done with a few supplies from a variety of shops.

Not quite as easy you can measure the optical data of an LED. Here you need much more precision in your LED test equipment.

Some of the interesting values include

• Spektraler Strahlungsfluss
• Peak-Wavelength
• Dominant Wavelength
• Center Wavelength
• X,Y Colorcoordinates
• C.C.T (Correlated Colour Temperature)
• C.R.I (Colour Rendering Index)

The aim is to get these values while processing and to reduce the error tolerance and speed up LED measurement time.
