Impact on your wellbeing and health
Cheap LED lamps produce most of their light in the high-blue spectrum. An overexposure to this kind of light will affect the body’s circadian rhythm. This is because the brain perceives blue light as the light from the sky and assuming it is daytime, the brain reduces production of melatonin, which controls sleep.
Melatonin is a natural hormone produced by your body’s pineal gland located just above the middle of the brain. During the day the pineal is inactive. When the sun goes down and darkness occurs, the pineal is “turned on” and begins to actively produce melatonin, which is released into the blood. Usually, this occurs around 9 pm. As a result, melatonin levels in the blood rise sharply and you begin to feel less alert. Sleep becomes more inviting.
This will make you feel unfocused and fatigued and also contributes to insomnia and seasonal affective disorder, both of which damage your immune systems, ending up feeling sick and reducing your productivity.
Another more obvious issue with cheaply produced LEDs is that their light flickers intermittently. While this flickering ranges from easily noticeable to imperceptible, it acts as a stress on occupants’ eyes as they struggle to adjust to the changing light and intensities. This creates repetitive eye strain and can contribute to the development of migraine headaches. Both of these conditions negatively affect worker productivity and if at home, you tend to feel uncomfortable and unwell.
Loss of Intensity
The issue that most low-cost LED lamps face is that, while they do not burn out in the same way as conventional bulbs, they lose light intensity over time. On average LED lamps last around 50,000 hours, however, some produce only 80% of their initial output after just 8,000 hours. This creates the additional cost of buying and installing replacement lamps and disposing of the old ones.
How Best to Avoid These Issues
It is important to understand that many of these issues are far less prevalent in more expensive, well-produced LED lamps. When creating your building design, a lighting design consultant makes sure to spec for high quality LEDs. It is important to know that this may not guarantee that you receive a quality product. It is fairly common for contractors to switch out the lighting spec’d by lighting designers for a similar, but less expensive product. Make sure to stay in contact with your contractor during the building process to ensure you receive the lighting your building was spec’d for by the experts in lighting who would most likely have exploited the option to explore the possibility of integrating natural daylighting into your building design as well.
