The WAL-SL-51-LED-12.4 temporary tunnel string light set from Larson Electronics consists of 51 industrial-grade LED lamps with 10 feet of 12/4 SJTW cable between each unit, stretching a total of 510 feet in length. Each globe light is equipped with a high-output LED bulb which delivers more light output than a 100-watt incandescent. Each LED light screws into a molded E26 lamp socket and the bulb is enclosed in a bird-cage-style plastic guard. The A19-style LED lamp produces 1,050 lumens per lamp, which provides a total of 53,550 lumens of bright white illumination. Each lamp housing is constructed from lightweight aluminum and fitted with an impact- and shatter-resistant polycarbonate diffuser. Each light has a plastic mesh guard enclosure that provides protection for the enclosed bulb and a hook eyelet that allows operators to hang these task lights overhead. Each LED lamp has an effective range that approximately covers a 5- to 10-foot radius with 10- to 15-foot candles of light. Multiple stringer sections can be daisy chained together via 5-foot whips terminated in twist lock connectors, with a maximum of 10 stringers daisy chained together. These LED lamps are suitable for wet areas, extremely long-lived, resistant to damage from impacts and vibrations, and consume far less energy than standard lamps. This tunnel string light is configured to operate with 277 volts electrical current.
Since these lamps use solid state LED technology, they can withstand vibration and accidental drops that an incandescent cannot. The bulbs provide additional safety measures and time savings, given the low heat production and 50,000+ hour runtime.
