How LED Lights May Be Wasting Your Business' Money
By Torrin Greathouse | October 05, 2017
While LED lights are one of the first solutions most business owners look to when they are trying to reduce electricity bills and make their facility more sustainable, they may end up costing a company more than they initially expect. Here are a few ways that using LED lighting can actually generate additional costs.
One of the key advantages of LED lights over older fluorescent or incandescent bulbs is that they last far longer. Their lifespan can be somewhat deceptive, however, because they do not burn out like other bulbs. Instead, their light intensity slowlyfades over time. Although LED bulbs are known to last 50,000 hours on average, some produce less than 80% of their initial light after only 8,000 hours of use. This creates additional costs for replacing the bulbs and properly disposing them. Because LED bulbs contain nickel, lead, and even traces of arsenic, they need to be professionally disposed of, which requires contacting local waste disposal experts. Not only that, but you face the additional cost ofpaying for maintenance when fixtures and bulbs wear out, as well as losing working hours in the areas where lights are being replaced.
LED bulbs are more efficient and produce higher quality light than other bulbs, but there are certain qualities to their light which could end up costing you money. Many LED lights produce a lot of light in the blue spectrum. This is an issue because overexposure to blue spectrum light is shown to destabilize the circadian rhythm. This results in problems sleeping, a lack of focus and energy at work, and ultimately decreased worker productivity. Another issue is that many LEDs produce light which flickers intermittently and can cause repetitive eye strain and in some cases evencause migraine headaches. Both of these conditions negatively affects workplace productivity, costing companies millions of dollars every year.
Effects on Employee Health
This same high blue spectrum light is also shown to have an adverse effect on our health.Overabundant blue spectrum light contributes to both seasonal affective disorder and insomnia. Insomnia and the symptoms of depression weaken the human immune system, making us more susceptible to illness. If employees are unhealthy, they are more likely to take sick days or work while they are sick, which reduces their productivity. Ensuring that your employees receive healthy light will improve their health and well-being while protecting your company’s bottom line.
