Ultra Performance Tube (UPT)

LED Tube

The Ultra Performance Tube System (tube + external dimmable driver) is the ultimate T8 or T12 fluorescent tube retrofit System. Our Ultra Performance Tube is the highest efficacy tube ever listed by DLC. An External Dimmable Driver is standard in this System designed to be the ultimate tube retrofit system in efficacy, efficiency and longevity.

When the objective is to minimize total life cycle cost of using LED tubes, Linmore’s Ultra Performance Tube System is the clear choice.

Applications: Commercial Lighting, Food Processing Lighting, Industrial Lighting, Office Lighting, Parking Garage Lighting, Warehouse Lighting.
