Made in the USA

The Larson Electronics WCDE-11-PLM50-16X500LTL-LED is a self contained LED lighting package that offers high output illumination and fuel savings over traditional light plants. This trailer mounted fold over 7-stage pneumatic light plant provides a safe and effective way for operators to quickly deploy the sixteen 500 watt LED light heads to elevations up to fifty feet. This pneumatic light tower folds over for easy transportation, features a hydraulic ram upright assist, air powered pneumatic mast and high output LED fixtures. The LED light tower is powered by a 11 KW Kubota diesel generator with a 110 gallon fuel tank. The entire assembly is mounted onto a 21` by 8` tandem axle trailer, allowing operators to transport this fold over boom from location to location.


The WCDE-11-PLM50-16X500LTL-LED Megatower™ is a self contained, towable, high power light tower package. This unit contains a water cooled diesel engine powering a 11KW Kubota generator, which supplies the current for sixteen 500 watt LED lights producing 60,000 lumens each, for a combined total of 960,000 lumens of light. This unit can run uninterrupted for up to 43 continuous hours without refueling and includes a pneumatic telescoping light mast which can elevate the sixteen high output LED lamps to a height of 58`. This mobile floodlight package is ideal for large scale event illumination, construction, mining, industrial operations, and anywhere a mobile full power lighting system capable of extended operation is needed.

This telescoping seven stage pneumatic light mast from Larson Electronics’ is designed to allow operators to quickly and safely deploy up to 8,000 watts of high intensity LED lighting in locations where illumination must be elevated to heights up to 58` for effective coverage. This light boom can be extended to 58` for maximum area coverage, and collapsed to 22` for applications where a footprint smaller is required. The tower is constructed of heat treated aluminum tubing with 2.69` foot of overlap per section. The mast is elevated using an included hydraulic ram, and extended to its full height using a trailer mounted air compressor.

A 90" wide by 109.5" tall and 2" by 2" by 1/4" thick steel mast head is attached to the upper section of the mast which provides a strong and stable platform for the sixteen 500 watt LED light heads.

Lights: Included with this light tower is one of our wet area suitable GAU-LTL-500W-LED high output LED fixtures producing a combined total of approximately 60,000 lumens at 500 watts. The light head contains forty-eight CREE® high output LEDs producing 1250 lumens each are arranged in rows and paired with PMMA high purity optics to produce a well focused 24° wide spot beam that is ideal for providing far reaching concentrated illumination while still covering a substantial amount of area. We also offer optional optics with 10° spot, 38° narrow flood, 60° flood, and 90° wide flood beam spreads. The spot beams are tightly focused and are designed for high elevation mounting to achieve distance, making spot versions ideal for high mast and spots lighting. The flood beams are designed to provide more light over a larger area nearer the fixture, making flood versions ideal for use as dedicated work and area lights. Each floodlight is securely fastened to the light boom and each lamp includes a support bracket to help maintain lamp stability within its housing. The lamps are hard wired into a NEMA 3R panel located on the end of the telescoping boom.

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.

Durability: As well as unparalleled heat control, the GAU-LTL-600W-LED series of LED lights from Larson Electronics also offer IP67 rated construction that is designed to withstand extremes of environmental and operating conditions. These units can withstand rapid temperature changes of -40° Celsius to +80° Celsius, are waterproof, and resist ingress of dust, dirt and humidity. The housings are formed from die cast aluminum and the optics are high transmission PMMA with 98% light transmittance. The CREE® LEDs help these units achieve resistance to vibrations and are rated at 70% lumen maintenance after 80,0000 hours of use. We recommend these LED lights for use in applications where a lot of vibration, dust, dirt, dampness and abusive working conditions are encountered.

Heat Management: Heat is the single largest factor in premature LED failure and color shifting. These LED units feature individual heat sinks per bank of six LEDs to control heat buildup rather than utilizing a single housing to dissipate heat. This allows for more thorough cooling of the LEDs for extended operating periods. This allows the LEDs to be driven at up to 90% capacity without overheating or visible loss of light output. The end result is more light with less heat and longer LED life with an average 70% lumen maintenance after 80,000 hours.

Telescoping Boom: The pneumatic telescoping boom is constructed of heat treated aluminum with an powder coated finish and extends up 58` in height. This boom is raised from and lowered to the folded position by a single hydraulic ram, and extended or retracted by pnumaitc system with equipped air compressor.

Wiring/Controls: The LED light heads are grouped into banks of four. Each bank in wired into the NEMA 3R breaker control box at the base of the mast. Operators control the light heads via an on/off switched breaker per bank of four light heads. The air compressor and battery charger are also powered from within this breaker box. Power is provided to the control box via an integraged 11KW genset. The mast elevation is controlled by a push button switch to operate the hydraulic ram, allowing operators to raise the mast to the upright position. The vertical deployment is operated by an up/down level, allowing operators to extend it to its full 58` height or retract it to the collapsed height.

Genset: The WCDE-11-PLM50-16X500LTL-LED Megatower™ includes a Kubota Lowboy II GL11000TM genset that houses a Kubota D722 diesel engine that powers the 11KW 120/240V brushless generator. This genset is liquid cooled and features a single phase generator with electric start ignition. The diesel generator runs at 3600 RPM and is equipped with an EPA/CARB Tier 4 emissions system. A 110 gallon fuel cell sits beside the genset and is equipped with an electric fuel delivery system. The fuel cell is constructed of single a heavy gauge steel single wall frame with internal anti-splash baffles. This genset features key operated electric starting, a twelve volt electrical system, liquid cooling, replaceable dry element air cleaner, and a full enclosure for safe operation and protection against the elements. This engine also features cold weather options to improve performance under cold weather conditions.

The image on the right is a Google Earth export of the physical area being illuminated, for scale purposes.

Trailer: The entire unit is mounted onto a four wheel, tandem axle trailer constructed of 8" box steel equipped with torsion axles. Each torsion axle is rated at 7,000 lbs and equipped with P235/80R16 tubeless tires and wheels. The rear axle is equipped with electric brakes. Tongue weight is rated at 650 lbs and an adjustable 3” lunnett eye for pintle hitches provides secure hookup to tow vehicles. A single 7,000 lbs rated tongue jack provides a stable connect-disconnect platform as well as additional stability during tower deployment. Standard heavy duty safety chains are included. This trailer also includes a front mounted storage area for stowing tools and accessories. The trailer is finished in industrial grade Dupont™ paint for protection against rust and corrosion and provides an attractive finish. Overall dimensions of the entire trailer and boom assembly in the stowed for travel configuration is 21` long by 8’ wide.

Six 7,000 lbs hand crank jacks are used for raising the trailer up off the ground, and four 7,000 lbs hand crank jacks mounted on extending outriggers are used for leveling and stabilizing the trailer assembly. Each of the four jacks are attached to a pivoting outrigger constructed of 6` by 6" by 6.3" steel I-beams. The jacks can be leveled by hand crank or attachment provided for power drills. These outriggers can be extended 6` out from the side of the trailer for added stability. This light plant can withstand 35 mph winds when fully extended. When lowered to 30`, the mast can withstand 50 mph winds. When lowered to 22`, the mast can withstand wind speeds up to 95 mph with gusts of 125 mph. Custom builds can be provided for higher wind speed resistance when fully raised.

Runtime: The sixteen 500 watt LED light heads have a considerably less amp draw than the metal halide light heads on traditional light plants. This allows the WCDE-11-PLM50-16X500LTL-LED to achieve up to 43 hours of continual use on a single tank of gas when only operating the light heads and air compressor. When running 24 hours a day and 7 days a week, this LED light plant will run for nearly 2 days straight without refueling. When the genset is running for 12 hours a day, this tower will provide on-site illumination for up to 4 days before needing more fuel. This self contained LED light plant provides operators with a worry free and energy efficient alternative to metal halide light plants.

We offer a choice of finishing, equipped light heads, and with or without gensets. These towers can be fitted with Larson Electronics line of high output light heads, or customize the mast head to meet the mounting requirements for your equipment. Optional diesel generators and fuel cells can be equipped from factory, or retrofitted after purchase.
