C. Output and Reliability Test:
Prior to testing, operate three decorative light strings for a 24 hour (± 1%) seasoning period at 120 V ± 1 V RMS AC.
Assemble the three decorative light strings into three flat test configurations. For each, wrap the string around a rigid
board or frame so that all are mechanically supported and oriented with the lamps directed outward. Tape the assembly
together with electrical tape to maintain the relative positioning of the lamps throughout the test. Next, for its optical
properties, white Teflon® tape shall be wrapped around the assembly to completely cover the electrical tape and wiring
harnesses. Ensure that the Teflon tape does not cover any part of the lamp or lamp socket.
Measure the light output of the assemblies while operating at 120 V ± 0.5 V RMS AC, 25°C ± 5°C and following the
guidelines contained in CIE Publication 084-1989, The Measurement of Luminous Flux. For decorative light strings that
modulate their light output (e.g., flashing, changing color), light output shall be measured over at least five (5) complete
cycles.
Keeping the testing assemblies intact (i.e., do not remove the tape, or move any of the lamps), operate each assembly for
1000 hours (± 1%) continuously. This period of operation (41 days, 16 hours) may be conducted using a test bench
facility (i.e., outside the measuring device), provided that none of the lamps in any of the assemblies have been moved
relative to each other.
After completing the output and reliability (previously referred to as lifetime) test, conduct a second measurement of the
light output on the respective sample of lamps following the same procedure above. Calculate the average maintained
light output for the three strings tested relative to the initial average measurement for those same strings.
For strings with colored lamps, the average maintained light output shall be no less than 70%. For strings with white
lamps or any phosphor-based lamps, the average shall be no less than 50%.
The average percentage of failed lamps on all three strings in the sample shall be no greater than 3%.
