The Appleton™ Mercmaster™ LED Low Profile Luminaires are reliable, light-weight, compact and ideal for task and area lighting applications under 20'. Field changeable globes, 6kV standard surge, and a choice of lumen outputs and Correlated Color Temperatures (CCTs) make this luminaire a great option for hazardous locations where corrosive atmospheres exist. These luminaires ensure uniform light distribution without spotlight effects or dark spots and can be tailored in the field. Also available in an Emergency Battery Backup version, it offers 90- or 180- minute modes. This is the one harsh and hazardous location luminaire you can specify to meet all your low-mount application requirements, without compromise.
