Mercmaster G3 lighting fixture is the first 100-watt HPS explosion-proof lighting fixture to achieve a NEC-501 T3 temperature rating (181-200 degrees Celsius). It is heavy duty engineered for Class 1, Div. 2 hazardous locations requiring a low operating temperature, and is especially effective in fueling areas, such as at an airport. Higher wattage provides for greater flexibility in lighting system design because fewer luminaries may be needed, translating into lower installation and maintenance costs with reduced downtime and less replacement lamps and parts, according to the company.
