Efficiency Vermont, Vermont's statewide provider of energy efficiency services, has announced a new program promoting the replacement of T12 and HID High-Bay lighting with more efficient technology.  The newLIGHT program is being made available from April 1st to December 31st, 2010, and is offering businesses significantly enhanced rebates for upgrading their old T12 fluorescent and HID high-bay lighting systems to more efficient equipment.  T Read more

While doing some research last week, I bumped into this great video that was put together by the folks at ElectricTV.net.  I was surprised to see the logo of one of our sister sites towards the end, so I decided to reach out and ask if they would let us embed the video here.  It's great to see all of the points we've been stressing about T5HO high bay lighting being repeated by a professional organization like NECA and IBEW. ElectricTV.net is Read more

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 th Read more

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 l Read more

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, Read more

We're often asked how 4-lamp T5HO High Bays and 6-lamp T5HO High Bay Fixtures fare when compared with traditional 400W Metal Halide fixtures.  The chart below compares 4-lamp and 6-lamp T5 fixtures against a traditional 400W Metal Halide High Bay along a number of dimensions.  The comparison dimensions are listed below with a short description of each.   400W MH Compared to 4-Lamp and 6-Lamp T5 HO High Bays Comparison Dimension 400W Met Read more

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 fluorescent lamp is eight-eighths (or one inch) in diameter and a T12 fluorescent lamp is 12 eighths (or 1 Read more
