How much light do you need?

According to the U.S. Department of Energy, lighting in a work environment can change moods, alter safety, and impact productivity. Finding the correct amount of light and the right type of light is key to any energy-saving strategy.

For example:

  • Check the quality of light in your workplace. Just because it’s bright, doesn’t
    mean it’s the best work light for the situation, or the most energy-efficient. In
    fact, it may be the opposite.
  • Experiment with different kinds of lighting. There is a difference between lighting
    day and night lighting.
  • Pay attention to task-specific lighting.
  • Remove any unused bulbs from fixtures and install lower-wattage bulbs

Over time, small changes in your approach to lighting can add up to big energy savings.

Some energy-saving tips include:

Clean the lighting fixtures and bulbs in your office and production areas on a regular basis. Dirt can absorb as much as 50 percent of your lighting.

Install Light Emitting Diodes  (LEDs) wherever you can. LEDs light up very quickly, can very easily be dimmed, and being constructed of solid state components, are difficult to damage with external shock, unlike fluorescent and incandescent bulbs which are fragile. LEDs can have a relatively long useful life of 35,000 to 50,000 hours. Fluorescent bulbs typically are rated at about 10,000 to 20,000 hours, and incandescent light bulbs at 1,000–2,000 hours.

Install Compact Fluorescent Lights  (CFLs) bulbs throughout offices, waiting areas, and any location a regular light bulb has been used in the past. CFLs are up to four times more efficient than incandescent bulbs and last up to eight times longer.
