DESCRIPTION

The Paralux III Series features recessed aesthetics and the latest in

energy efficient technology. The luminaire incorporates a nominal

3" deep precision cell louver into a 4-3/4" deep para-contoured

fixture housing. This combination creates a total high performance

parabolic optical assembly for optimum performance. The series is

compatible with all of today’s popular ceiling systems and is

available with a number of options and accessories for application

versatility. 2EP3-IC is rated for installations when the housing is in

direct contact with insulation. The high performance luminaire is

designed to offer maximum efficiency and performance for today’s

unique interior specifications. The Paralux III series is an excellent

choice for commercial office spaces, schools, hospitals or retail

merchandising areas.
