Sturdilite® Master Series HI | Low-voltage LED Floodlight

Impact-resistant DC work lights built for a wide range of heavy-duty mobile equipment


The Sturdilite Master Series is Phoenix’s premium line of super rough surface, heavy-duty LED work lights designed for mining, construction, forestry and agricultural mobile equipment. Fixtures are tested and approved for rugged and dusty terrain at night and low visibility conditions to ensure operator safety and to deter costly accidents. The Master Series is constructed with stainless steel hardware, an impact resistant polycarbonate or tempered glass lens and a heavy-duty harp to withstand extreme shock and vibration.

The Master Series HI comes in a range of beam patterns to optimize light output and distribution so equipment can operate 24/7. The Master Series HI is available with cool white LEDs that maximize efficiency and minimize glare in clear conditions. The fixture is also available with amber LEDs for improved visibility during inclement weather such as fog, dust, rain and snow.

Fixtures are designed for easy installation on all OEM brands of equipment, including Caterpillar, Komatsu, Liebherr and more. They are also suited for installation on patrol boats, pickup trucks, water trucks, forklift trucks, utility vehicles, reach stackers, crane cabin lighting and a variety of other mobile equipment.
