The retrofit troffer is available 2x2, 2x4, 1x4 and is now field adjustable, with three selectable wattages and color temperatures, giving you complete control over your lighting needs. The RTLED can be retrofitted into an existing system by one person in under 3 minutes vs. 20 minutes for a complex, full fixture replacement. Multiply that savings across an average office retrofit project and you're talking big bucks!
