  • Inspection Test
  • Electrical Test
  • Lifetime Test
  • Weathering Test

1) Definitions

A. Decorative Light String (DLS)A string of lamps that operate on AC power in North America (120 VRMSAC, 60 Hz) or via a power adapter or controller that connects directly to AC power, and is used for decorative residential lighting purposes. The lamps may be replaceable or sealed into the lamp holder/wiring harness, and may be assembled in a net or icicle configuration.
B. Failed LampA lamp has failed if the light output is less than half the expected output for a comparable lamp of the same age in good condition. This will normally be determined by comparison with a good lamp of the same colour on the same string.
C. Input PowerThe average total power used by the decorative string during operation, measured in watts, including (if any) the transformer, adapter, controller, etc. For decorative light strings that operate with power adapters that can accommodate more than one string, the input power is defined as the average total power consumed with the rated maximum number of strings attached.
D. Maintained Light OutputThe average light output of a decorative light string after a testing period expressed as a percentage of light output of that same string following a 24-hour seasoning period.
