Sturdilite® Master Series | Low-voltage LED Floodlight

Impact-resistant work lights built specifically for heavy-duty mobile mining equipment


Durable work lights designed specifically for heavy duty mobile mining equipment such as haul trucks, dozers, wheel loaders, DC drills, hydraulic excavators, and graders. The Master Series comes in various beam patterns to optimize light output and distribution, and to allow each piece of equipment to operate 24/7. The Master Series is designed for easy installation on all OEM brands of equipment, including Caterpillar, Komatsu, Liebherr and more.

Tested and approved for rugged and dusty terrain at night and low visibility conditions to ensure operator safety and deter costly accidents. Built with stainless steel hardware, impact resistant polycarbonate or tempered glass lens, and a heavy duty harp to withstand extreme shock and vibration. A No-Glare (driving) optic is available for a clear cut-off point that reduces glare, improves comfort and visibility for operators of oncoming vehicles.

Available in cool white light that maximizes efficiency and minimizes glare in clear conditions, as well as amber light for improved visibility during inclement weather like fog, dust, rain and snow.

These fixtures are also suited for installation on patrol boats, pickup trucks, water trucks, forklifts, utility vehicles, construction equipment, reach stackers, crane cabin lighting and a variety of other mobile equipment.
