Benefits of T5 HO High Bays

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 T5HO high bay fixture offers over traditional 400 Watt Metal Halide high bays.  These include energy efficiency, improv … Continue reading

T5HO Warehouse Lighting Application Guide

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 on … Continue reading

Gymnasium Lighting

For years, the standard method of lighting gymnasiums has been the 400W Metal Halide High Bay. This has led to gyms with deteriorating light levels and poor playing conditions that are expensive to operate. New technologies have allowed lighting designers to specify T5 High Output (T5HO) Fluorescent High Bay Fixtures in place of the more inefficient metal halide fixtures. This shift has reduced the power consumption of gymnasium lighting systems, provided better quality light for all sports activities, and has allowed for a more versatile environment in school or recreat … Continue reading
