These heavy duty string light sets are manufactured with 150 mini light bulbs spaced approximately 5.75" apart on 20 AWG wire. These are a favorite light string for installers and cities who purchase lights for large tree wrapping projects.
These lights are manufactured with larger gauge wiring allowing an impressive maximum run of six (6) sets of light strings end to end for a total of 413 continuous feet. This reduces the required number of extension cords and splitters. Less accessorires translates to saving money and time.
