The LM-25-3S-4X400W-LED 1600 watt telescoping steel light mast with 1000 watt metal halide equivalent LED light heads from< Larson
Electronics’ is designed to quickly and safely deploy 1600 watts of intense LED lighting in locations where elevated illumination is needed for
maximum area coverage. This light boom can be extended to twenty-five feet for maximum area coverage and collapsed to twelve feet for
applications where a footprint smaller is required. The tower is constructed of square steel tubing with a lower section 10' in length and 4" by 4"
by 1/8" thick, middle section 9.5' in length and 3" by 3" by 1/8" thick, and an upper section 8.5' and 2" by 2" by 1/8" thick. Each section has a 1'
overlap minimum. The mast is elevated using an included 2,500 lbs hand winch with 3/16" galvanized steel cable and extended to its full height
using a second 2,500 lbs hand winch.

Lights: The lighting system on this articulating light mast is comprised of four our of GAU-LTL-400W-LED 400 watt LED lamps producing 52,000

lumens of light each attached to the end of the telescoping pneumatic light boom. These floodlights produce a wide flood light pattern with a
combined total of 1,600 watts and 508,000 lumens of light. The GAU-LTL-400W-LED lights are ideal replacements for fragile and hot running
1000 watt metal halide lamps, offering increased durability, longer lamp life, and lower power consumption. The entire lighting assembly is
connected to the power source via a 4-switch control box. Each light head is on an individual circuit and can be powered on or off independently
of the other light fixtures.
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. In addition, should an
LED failure occur, these LED flood lights are field serviceable. Each bank of six LEDs can be replaced with the fixture installed. This allows for
the tower to stay in operation until repairs can take place, and eliminates the need to remove and disassemble the entire fixture for repairs.
Durability: As well as unparalleled heat control, the GAU-LTL-400W-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 Bridgelux® LEDs help these units achieve resistance to
vibrations and are rated at 70% lumen maintenance after 80,0000 hours of use. We use these LED lights for applications where a lot of vibration,
dust, dirt, dampness and abusive working conditions are encountered.

The above image shows the comparison of the traditional 4000 watt metal halide light plant such as our LM-25-3S-4X1000W (left) to the LM-25­3S-4X400W-LED LED light tower. The area being illuminated by each tower is 300' in length and 250' in width. Unlike the metal halide light
plant, there are no hot spots with the LED plant. This high output LED light plant provides an even beam spread over the targeted work area
without overcast, glare, light spillage, and wasted illumination. Color rendering is also increased with LED light plants, providing a more realistic
night vision that more closely resembles natural daylight illumination.

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.
Each floodlight is securely fastened to the mast head with an innovative trunnion style stainless steel mounting bracket that allows the light to be
adjusted through 180° of vertical movement. The LED light head is secured to the mounting bracket with shock dampening rotating inserts. The
insert provides precision aiming down to 1° while providing increased longevity to the LED fixture. To vertically adjust the unit after mounting, the
user simply loosens the screws located on either side of the unit, moves it into the desired position, then re-tightens the screws. The base of the
mounting trunnion is equipped with several machined slots which allow users to utilize existing mounting holes and slide the unit for precise
mount positioning.

The LM family of telescoping towers feature a proprietary mast guidance system, which provide increased stability during high winds. When
lowered to 12 feet, the mast can withstand winds up to 125 mph. When elevated to its full upright position, the mast can be rotated a full 360°. By
loosening the T-Handle, operators can rotate the mast with easy in either direction. The mast can be positioned in one of four different directions,
and locked back in place by re-tightening the T-handle. The mast itself spins freely with easy, and can typically be rotated with a single hand.
The LM series of towers are powder coated with glossy blue finish for corrosion resistances and aesthetics. These light masts are typically
mounted to trailers or other stable surfaces via a 15 inch by 13 inch, 1/4 inch thick mounting base-plate which has been drilled to accept six 5/8"
anchor bolts. A 52" long mounting plate constructed of 2" by 2" by 1/4" thick carbon steel is attached to the upper section of the mast which
provides a strong and stable platform for the four LED fixtures.

Voltage: The drivers in this unit provide the ability to automatically monitor and adjust input current to maintain the correct LED voltage levels
