Manufacturers of light fixtures cut costs by 30-40% by using LED light engine circuit boards that are twice the length of conventional models.
“On the average four-foot linear LED fixture we’re saving at least $3.50 on each unit,” says Tom Kearney, COO.
Kearney saw the need for interior lighting that was not only brighter, but also more efficient, in the typical manufacturing plant and office space. His solution was to replace T5HO lighting with more efficient LED lamps that have a life expectancy of 100,000 hours.
“I thought there was considerable room for improvement through upgrading to LED lighting, especially in business and industrial facilities where the high-pressure sodium or fluorescent lighting is often horrible,” he says. “The longer LED circuit board has added to that opportunity.”
The conventional light engine – the circuit board used to power more efficient and longer-lasting LED lamps – was in the past normally limited to approximately two feet in length. This meant that the assembly of linear LED fixtures, such as the four- or eight-foot models that are typically used to replace fluorescent lights, would require two or four boards attached in series or parallel end-to-end.
As Tom Kearney explains, with the introduction of the extended-length light engines, it takes only one board to power a typical four-foot linear LED fixture, and just two boards for an eight-footer.
“Since each board contains connectors at each end, by using a single, extended-length board for a typical four-foot fixture I’m saving six to eight connectors on each one. In addition, I’m probably seeing a 20-25 percent savings on labor, plus there is a considerable savings on production time.”
The extended-length circuit boards, or light engines, are manufactured by MADE (Manufacturing And Design Electronics – formerly CI Lighting), Auburn Hills, MI.
Kearney selected this supplier not only because it was an innovator of the extended-length board, but also because the company performs 100% comprehensive testing, control and data reporting and recording,
“MADE does this automated inspection of each LED circuit board, ensuring that it lights properly, the color temperature, power output, brightness, and color rendering index are correct,” Kearney explains. “As a result, all of these things that I would have to do myself are already done when the products arrive at my facility. And that provides an important quality assurance as well as added savings.”
