For far too long, the standard for lighting warehouses, industrial facilities, manufacturing facilities and other high ceiling height applications has been the 400 Watt Metal Halide fixture. Advances in ballast technology and the improvements of the T5 High Output (T5 HO) Linear Fluorescent lamp have led to many new light fixtures that are targeted specifically to replace old HID high bays.

The following article details the many benefits that the T5 HO high bay fixture offers over traditional 400 Watt Metal Halide high bays.  These include energy efficiency, improved lumen maintenance, instant start, more usable and better quality light and improved color characteristics.  To find out if T5 HO high bay fixtures are the best choice for your application, don’t hesitate to contact us.

The vast majority of existing warehouse space in the US is lit with inefficient high intensity discharge or magnetically ballasted T12 fluorescent light fixtures.  Unfortunately, lighting is one of the few areas that is often overlooked when investigating cost reduction opportunities.  Owners and managers blindly budget tens to hundreds of thousands of dollars for utility bills without realizing that switching to more energy efficient warehouse lighting can provide a tremendous opportunity to reduce energy demand and therefore cut utility costs.  Many believe that the only option to lowering the electric bill is to shut off all the lights in the facility which results in an unsafe work environment.  We have had major advances in lighting technology that allow for warehouses lighting systems to be optimized for bulk storage and rack aisle applications.

This application guide outlines warehouse lighting requirements and best practices and gives practical examples you can use as a basis for your warehouse lighting retrofit project.  As with our gymnasium lighting application guide, we will use examples to illustrate these guidelines that are based on typical warehouse layouts.  If you have any questions or need any clarifications, don’t hesitate to contact us.

T5 and T5HO fluorescent high bay fixtures and other T5-based specialty lights are built around a linear fluorescent tube lamp.  Like other types of lamps, the number in the name of the lamp reflects its size.  The “T5” name reflects the diameter of the tube in eighths of an inch.  A T5 lamp is five-eighths of an inch (5/8”).  Similarly, a T8 lamp is eight-eighths (or one inch) in diameter and a T12 is 12 eighths (or 1-1/2 inches) in diameter.  One of the features that make a T5 bulb and T5-based high bay light fixtures more efficient is the fact that the lamp is 37% narrower tube than a T8 and over 55% narrower than a T12 lamp.

This article describes the background and technical specs of the T5 and T5HO lamps as well as some considerations you should keep in mind when relighting your facility with these types of lamps.
