250 Watt Temporary Construction String Light - 10 LED PAR 38 Work Lights - 120-277V - 12/3 SJTW

Part # WAL-SL-10-PAR38-LED-12.3    Price: $1,259.52

Spec Sheet   

The Larson Electronics WAL-SL-10-PAR38-LED-12.3 Work Area String Light is designed for high output job site illumination. This unit features ten 25 Watt LED lamps producing 25,000 lumens of illumination with a lifespan of 50,000 hours. This work light comes with 10` of 12/3 SJTW cable between each lamp, allowing for temporary work light illumination spanning over one-hundred feet. This light fixture features a low amp draw and is wet area approved, making this string light applicable to a number of outdoor work conditions requiring temporary high output illumination.

The WAL-SL-10-PAR38-LED-12.3 work area string light consists of ten industrial grade 25 Watt LED lamps with ten foot of 12/3 SJTW cable between each unit. This temporary LED string light is connected to power via an integrated 3 foot cable terminated with an industrial grade plug and connector for daisy chain connection. Each lamp socket is equipped with a high output PAR 38 LED bulb which is a more energy efficient lamp than typical 150 Watt PAR38 lights. This work string light features a hook eyelet, making it versatile for a number of industrial applications requiring reliable and bright illumination.

The WAL-SL-10-PAR38-LED-12.3 work light fixture features ten 25 watt LED PAR38 lights, for 250 Watts total. This series of temporary work lights serve as a direct replacement for 150 watt PAR38 and 300 watt incandescent temporary work lights while overpowering traditional stringers. This temporary LED work light is a far more energy efficient bulb, and provides 25,000 lumens at 250 watts and an 80% lumen retention at 50,000 hours, compared to the 2,500 hour lamp life offered by standard 150 watt PAR38 halogen lamps. The LED PAR38 lamps have a lower energy consumption, produce more light output, are more durable to abuse and harsh environments, which translates into less maintenance required by operators and huge savings long term.

These LED work string light consist of 100` of 12/3 SJTW cable, with 10` between each lamp and terminated in 3` of whip on the front and back ends for a total of 106` of durable, weather proof string lighting. 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 LED lamps as halogen. Each LED trouble light has an effective range that approximately covers a 15` to 20` radius with a 60° flood beam.

Unlike gas burning and arc type lamps that have glass bulbs, LEDs have no filaments or fragile housings to break during operation. Instead of heating a small filament or using a combination of gases to produce light, light emitting diodes (LEDs) use semi-conductive materials that illuminate when electric current applied and emitting light. With LED lights, there is no warm up time or cool down time before re-striking and provide instant illumination when powered on, adding to the reliability of LED technology. By nature, LED light sources run significantly cooler than traditional 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 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 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 do 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 traditional light source, and thus does not present a significant burn risk if an operator or bystander accidentally brushed up against an exposed lamp, and reduce the fire hazard should they fixture accidentally come in contact with a flammable material for a short period of time. This significantly increases the safety within the work environment.

Wiring and Plug: This temporary string lighting system is constructed of 12/3 STJW cord that is fitted with an industrial grade cord cap for easy connection to common wall outlets. Plug options include standard NEMA 5-15 15 amp straight blade plug and NEMA 5-20 20 amp straight blade plug for 125V outlets, NEMA 6-15 15 amp straight blade plug and NEMA 6-20 20 amp straight blade plug for 220V-240V outlets, and a two pin 16 amp rated Schuko plug with ground contact and socket for European outlets up to 250V. Alternatively, we can provide flying leads with no plug for hard wire applications or for operators who prefer to wire in user provided cord caps. Please choose pigtail option below for flying leads with no plug.

These lights are configured to operate with 120V-277VAC or 11-25V DC without any modifications. These LED string lights provide more and better quality illumination than 150 watt halogen string lights without the high heat and fragile glass construction of traditional lamps. 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.
