Obviously organisations need buildings, which need to be lit, of course – but most of all they need stimulated, healthy and committed employees and as such, getting the best out of your workforce means giving them a quality and comfortable environment that aids their concentration and gives them daylight indoors.
MHA’s portfolio of energy efficient LED lighting products are suited for a variety of internal and external environments, including precision manufacturing, food production and high-risk environments, where it is imperative that light output, light quality and uniformity are high quality – so as to aid precision working and safety.
This is already proven with our customers who manufacture medical supplies, food and essential pieces of safety equipment where lives are at risk if any imperfections occur.
LED Lighting – the benefits, researched-based
The benefits of LED lighting go beyond the sales literature, as studies from Netherlands-based Maastricht University show, how lighting can have a positive impact on the healing environment.
This research, along with other studies show light has a positive effect on health, mood and well-being, not just for people in a care environment but also for healthy people.
Further exploration into how lighting affects people’s well-being and performance-levels indicates that the human eye and the human brain are very sensitive to light quality where colour temperature, absence from flicker, glare and hum, as well as correct colour rendering are all key factors. LED lighting – unlike existing artificial light sources – does not produce potentially harmful heat, infrared or UV radiation.
This indicates that LED light sources could be important to a healthy environment, as well as the huge cost savings and massive reduction of C02 emissions.
Additionally, certain wavelengths are known to be conducive to certain biochemical reactions such as hair growth, production of vitamin D, mood and emotions as well as the levels of some complex dopamines and enzymes.
The incidence of SAD – seasonal affective disorder – is well documented in northern latitudes during the shorter daylight hours of winter months. The effective treatment is for sufferers to sit in front of a suitable wavelength light source to top up the body’s light deficiency.
Apart from being a subtle but significant environmental factor, light is fundamental to virtually all living cells and thus careful selection and deployment of the right lighting conditions can make a big difference to health and well-being, both physically and mentally.
LED lighting is a more controllable type of illumination and overcomes many of the drawbacks and disadvantages of existing conventional light sources.
All forms of electromagnetic radiation have an effect on living organisms and this field is one where further study could produce some interesting facts that will help us develop the best environmental conditions and possible therapeutic applications for light.
Light – as well as temperature, humidity, ventilation, air quality, barometric pressure, vibration, sound, electrical charge, negative ion concentration and magnetic fields – are all conditions with direct effects on the human body.
LED Lighting – the pitfalls and how to avoid them
Of course all of the above benefits will materialise only if a high quality and high reliability LED fitting is installed. The LED market as described above remains a young & immature one, notwithstanding the huge growth it is experiencing.
Light quality from a LED source varies significantly between good and bad examples for a number of reasons. Light emitted from the LED itself is a focussed beam and if not optically-managed effectively, the transmitted light from the fixture will be highly directional, non-uniform and very unpleasant (if not painful) on the eye.
Colour temperatures and colour rendering (CRI) which are crucial to high quality lighting are frequently abused by suppliers of lower quality fittings who use “cold” colours which produce blue-tinted light (to appear brighter than they actually are).
Product Reliability & Longevity of a LED lighting fixture is crucial. LEDs claim to have a “long life” and as they are much more expensive than traditional fittings and long life is crucial to justifying the capital investment. The industry being both young and immature, with an abundance of “horror stories” detailing failed fittings with questionable warranties.
Worse still, the biggest cause of failures is poor thermal management of the LED, such that it burns out over time rendering the fitting completely redundant.
The good news being that these pitfalls can all be easily avoided provided one knows what to look for.
Test documentation (from qualified 3rd party European Test Houses) for photometric data, Manufacturer’s LED specification, including LM80 “life” and “lumen depreciation testing, coupled with the equipment manufacturer’s TM21 test reports as well as basic CE qualification which should all be available from a professional manufacturer and supplier of LED fixtures. If it’s not – then don’t touch it!
