Switching all of the bulbs in a commercial building may seem like a huge undertaking, but if you switch them to light-emitting diodes (LEDs), the task is worth the time. LEDs have emerged as literal and figurative bright spots in the lighting industry, providing several benefits for your building, including in the economic, environmental, and health arenas.
Lighting that uses LEDs has major economic benefits. The bulbs, once very expensive, have come down substantially in price. These LEDs use very little energy, less than many compact fluorescent bulbs, and the effect on your monthly utility bill will be swift. Your overall operating budget will also see a reduction in the amount needed to purchase new bulbs because LEDs last for many years.
One more financial benefit is that your air conditioning bills could go down in summer. If you're switching from halogen or incandescent bulbs, you'll notice a drop in temperature. Halogen and incandescent, even the newer energy-efficient ones, give off a lot of heat. In summer, you have to increase your air conditioning to make up for that. LEDs run very cool, you still don't want to touch them when they're on, but they give off less heat than other bulbs.
One of the issues that fluorescent-bulb users face is disposal. Those bulbs have traces of mercury and require extra care. LEDs do not have mercury and can be disposed of like old incandescents. There is also less risk to health if an LED happens to break, though broken glass will still be an issue. You just won't have to deal with the mercury.
Workers and customers inside your building may also experience some health benefits. LEDs don't flicker like fluorescents can, leading to fewer complaints about headaches or eye strain. If health improves, morale can improve as well.
Making a large-scale change like switching all the lighting in your building may take some planning. However, it is planning that will have excellent effects over time.
