The Larson Electronics HALD-48-1X4-2X50LED-DIMM Explosion Proof 0-10V Dimmable LED Light is a powerful lighting
solution for combustible sites and industrial facilities. This 100-watt front-access LED lamp is an excellent replacement or
upgrade option for paint booths and hazardous locations where flammable chemical/petrochemical vapors are present.
Constructed of copper-free aluminum, with a powder coated finish, the 1x4 lay-in fixture is compatible with recessed
mounting applications.
WIRING
Standard pigtail(flying leads) wiring
We strongly encourage a licensed electrician install this product,in all locations especially in outdoor
areas where weatherproofing may be required. Universal voltage driver permits operation at 100V - 277V AC, 50 or
60Hz.
MOUNTING
This 0-10V dimmable fixture is designed for recessed mounting applications and requires a mounting hole to be made in
booth panels capable of accommodating the fixture's housing in order to provide the maximum amount of space in paint
spray booth enclosures. Once mounted, this fixture's door frame will extend 3/8” into the spray booth.

DIMMING
This LED light fixture features 0-10V dimming capabilities. This gives operators the ability to manually adjust the
brightness of the LED lamp quickly and easily. The 0-10V dimming allows for adjustments to fit the brightness
needs of any lighting situation. A 0-10V dimmable light works through the use of a DC control signal that ranges
between zero and ten volts. The basic idea is that at 10 volts of input the light is at its brightest level with 0 volts
being the lowest possible dimness setting. The smooth, continuous and flicker-free dimming of a 0-10V dimmable
LED light is ideal for a wide range of different lighting applications.
Voltage: Check product label for correct voltage.
WIRING (see attached wiring diagram)
This unit comes preconfigured in selected voltage and beam configuration. Wire light tothe correct
voltage. Follow all applicable local, state, and National Electrical Code for the hazardous area.
Wire size is 18/5.
