Companies waste millions on inefficient lighting
January 15, 2008
Lighting is typically the last line item on the budget operators worry about or assess. Many companies feel as though they have no control over their energy costs, so they never take a critical look at the expenditure. It's just an item on the budget that has to be paid no matter what the cost. However, such costs can result in millions of dollars of lost revenue each year, not to mention tons of wasted energy and a negative impact on the environment.
Operating costs can stack up quickly, significantly affecting the bottom line. Simple solutions to cut such costs sometimes are overlooked simply because operators aren't aware of cost-effective measures that could have a noticeable impact on daily operations and expenses. One of those simple solutions is lighting.

However, such costs can result in millions of dollars of lost revenue each year, not to mention tons of wasted energy and a negative impact on the environment.
Industrial buildings are not designed with lighting efficiency in mind. In fact, the vast majority of manufacturing plants are wasting half of their energy every year using the most common type of lighting—metal halide. Metal halide lights lose 35 percent of their light output during the first year of use. After three years, light output is just 30 percent of the original design.
Even though light output goes down, the energy bills don't. Manufacturers continue to pay the full light bill for less than half the light.
The fact is, most manufacturing companies can cut lighting costs by 50 percent to 70 percent each year and have better lighting by switching to energy-efficient lights. The new energy-efficient lights last three times as long—36,000 hours compared to 12,000 hours. This cuts maintenance costs by half.
On top of the savings and improved work environment, companies can capitalize further by taking advantage of the Energy Policy Act of 2005 (EPAct 2005), a federal tax deduction for energy efficiency that applies to lighting upgrades. EPAct 2005 allows energy users to take a one-time federal tax deduction of 60 cents per square foot for upgrading to energy-efficient lighting.
Taking into account only these tax deductions, a company can implement an energy-conscious lighting program rest assured the move will make a positive impact on the bottom line. In addition to the direct monetary savings companies achieve, they simultaneously improve the indoor work environment through better-lit work areas.
Take Atlas Foundry in Marion, Ind., for example. By using energy-efficient lighting and motion sensor controls to turn off or dim lights when areas of the plant are unoccupied, the company gained a $20,400 tax deduction under the EPAct for energy efficiency. Considering the amount of energy saved with the use of more energy-efficient lighting, Atlas Foundry also helped to reduce air pollution by 340,000 pounds a year, or the equivalent of exhause from 578 cars over the next 20 years.
Jim Gartland, Atlas Foundry's president and CEO, said employees appreciate the new lighting and are pleased with an improved work environment.
But deciding to take a look at lighting is only the first step in an important process. Many lighting companies and suppliers sell lights. The challenge is that every facility is different, and each has distinct needs and uses for lighting. Therefore, sifting through hundreds of available lighting products to find the right solution for each facility can be time-consuming at best.
If you are considering upgrading lighting and relying on a turnkey supplier, make sure to examine the following:
When deciding whether to upgrade lighting, also consider a full energy audit. This audit should account for all lighting in the building as well as the traffic and work flow on any given day. The audit will provide you with a lighting strategy that outlines an effort to save energy as well as improve operations and safety through quality lighting.
Finally, be sure the lighting upgrade will cause little disruption in operations during the transition. When upgrading lighting, there should be little for you to do other than turn on the lights and save.
