Made in the USA

The Larson Electronics WAL-SL-51-PAR38-LED-12.4 Temporary Tunnel LED Lighting String Light System is designed for high output
illumination and daisy chain connections across a total length of 510' away from the power source. The 25 watt PAR38 LED lamps on
this work site light set provide more and higher quality light than 300 watt rough service lights while creating less heat and using less
power. This LED light stringer operates on 277V AC and provides operators with a temporary work light solution for tunnels and
underpasses up to 2,000' in length.

This temporary tunnel string light consists of 51 industrial grade PAR38 LED lamps with 10' of 12/4 SJTW cable between each unit, stretching a
total of 510' in length. This temporary LED string light is connected to a 277V power source via an integrated 5' line-in cable. Each globe light is
equipped with a high output LED PAR38 bulb which delivers more light output than 300 watt rough service bulbs and 150 watt PAR38 halogen
lamps. The 25 watt LED bulb draws less than 10% the electrical power of a standard 300 watt bulb and less than 20% of standard 150 watt
PAR38 lamps, making it suitable for tunnel and temporary lighting applications where long spans are required. Each LED light screws into a
molded E26 lamp socket.
Fifty-one high output PAR38 style LED lamps producing 2,500 lumens per lamp provide a total of 127,500 lumens of bright white illumination.
Each lamp housing is constructed from light weight aluminum, and fitted with an impact and shatter resistant polycarbonate diffuser. These LED
light bulbs provide additional safety measures and time savings, given the low heat production and that it does not require replacing for 50,000
hours. Since the LED bulb uses solid state technology, the vibration (dropping, etc.) that degrades conventional incandescent bulbs is not an
issue with these LED bulbs.

Unlike the glass tube design of traditional fluorescent lamps, these LED lamps have no filaments or fragile housings to break during operation.
Instead of using a combination of gases to produce light, light emitting diodes (LEDs) use semi-conductive materials that illuminate when electric
current is applied, emitting light. With LED lights, there is no warm up time or cool down time before re-striking and they provide instant
illumination when powered on, adding to the reliability of LED technology. By nature, LED light sources run significantly cooler than fluorescent

lamps, reducing the chance of accidental burns and increased temperatures due to heat emissions. This solid state design of light emitting
diodes provides a more reliable, stable, durable, and energy efficient light source over traditional fluorescent lighting.
Safety within the workplace is another benefit of LED work lights and temporary lighting. All light sources produce heat. With traditional work
lamps, such as incandescent and halogen light sources, the lamp reaches high surface temperatures. These surface temperatures introduce a
burn risk to anyone that allows prolonged skin contact with the light source, as well as a fire hazard if a flammable material is accidentally set too
close to the light source for an extended period of time. While LED fixtures still produce heat, they are designed with heat sinks to properly
disperse the heat. Each LED bulb is engineered to disperse and expel this heat quickly and efficiently, keeping the lamp cooler than traditional
light sources. This LED work light operates at a lower surface temperature than a comparable model with a traditional light source, and thus does
not present a significant burn risk if an operator or bystander accidentally brushes up against an exposed lamp, and reduce the fire hazard
should the fixture accidentally come in contact with a flammable material for a short period of time. This significantly increases the safety within
the work environment.
Each light has a hook eyelet that allows operators to hang these tasks lights overhead. Utilizing energy efficient LED lamps, operators are able to
provide more light coverage from the same amp draw, or lower the amp draw using the same amount of LED lamps as incandescent, compact
fluorescent, or halogen lamps. Each LED trouble light has an effective range that approximately covers a 10-12' radius with 20-30 foot candles of
light when mounted at 10-15' above the work environment. Unlike fragile incandescent and compact fluorescent lamps that are made from glass,
these LED bulbs are extremely durable and can live up to the abuse of harsh working conditions. With a lamp life of 50,000 hours, operators are
not constantly having to replace burnt out or broken lamps, reducing down time and lowering the amount of spare lamps required at the job site.
Multiple stringer sections can be daisy chained together via 5' whips terminated in twist lock connectors, with a maximum of four stringers daisy
chained together. Alternating hots between each daisy chained unit allows these string lights to be connected together, spanning up to 2,040' in
length. Previously, it would have been unrealistic to have a complete assembly reaching 510' in length from a single point of power.
