Ultra Performance High Bay (UPH)

Linmore LED Labs Ultra Performance High Bay (UPH) is the ultimate high bay fixture. Period! When designing the UPH, we considered all aspects of owning and maintaining a high bay lighting system from energy consumption to ease of ownership. The UPH is differentiated by features found on no other high bays. The patented ParaBar™ High Bay Light Bar System is comprised of the highest efficacy LEDs mechanically bonded to an extruded aluminum light bar with parabolic, ultra-reflective sides. The amount of light and the consistent distribution of light per watt of energy consumed is unmatched by any other high bay. When the objective is to utilize a high bay lighting system with the least amount of energy, the least amount of maintenance, best warranty, and designed for decades of effective life, the Linmore UPH is the clear choice.
