First, enter a description of the LED light source tested. Then complete the fields labeled "LM-80 Testing Details".Test duration must be at least 6,000hours. If only one ca temperature data t is to be ud (no
interpolation), complete only "Tested ca temperature 1". For only two ca temperature data ts, complete 1 and 2.
Next, further to the right, in the
