The Mercmaster™ III 50-250 Watt luminaire has a modular design that allows for scores of fixture component combinations to meet installation and lighting needs. The enclosed and gasketed construction allows it to fit a vast range of applications and is suitable for NEC and CEC Class I, Division 2/Zone 2; Class II, Division 1 and 2; Class III and other robust environments. Designed to dissipate heat from the ballast components out, Appleton's thermal performance with the Mercmaster III leads the industry. Appleton's heat reducing internal control design results in 18% cooler operation, which increases fixture durability and enables the Mercmaster III to be used in ambient temperatures up to +65°C (+149°F).
