The evolution of lighting is nearly 2 million years old. For most of human history, we relied on the natural light of the sun and stars to work. This was essential when we lived in agricultural communities but our cities and businesses now run 24/7. Without proper lighting, our modern way of living would be impossible.
Lights use over
58,000 terawatt hours of electricity a year across the UK. This is the light we
use in every business, home, and street in Britain.
Let’s look at
the history of lighting, from fire to LEDs, and see how lighting has developed.
Manufactured light was one of the first inventions of mankind. Our ancestors used primitive tools to create fire on demand instead of relying on lightning to set fire to brush and ancient woodland. This became widespread by 125,000 BC which allowed humans to occupy their first ever shelter – caves.
The evolution of lighting and shelter go hand in hand. It wasn’t until 4500 BC that humanity would be able to sustain a light source without managing it. This was when the basic oil lamp was invented which was then followed by the candle in 3500 BC.
electricity, lamps were the focus of development by inventors. The Argand lamp
was invented in 1780 and it became a must have product in 18th century Paris.
This was because the lamp was much more efficient and it generated ten times
the light that a single candle could.
In 1792, the first gas lamp was invented by William Murdoch which revolutionised the use and evolution of lighting outside of the home.
Before the 19th
century, factory work was perilous. Early cotton mills relied on water or steam
engines and any stray machinery could harm a worker if they couldn’t properly
repair it. It was Philips and Lee’s cotton mill in Salford that began to change
this by employing gas lamps.
developments pushed forward the mining industry. Humphrey Davy’s safety mining
lamp allowed coal miners to avoid setting alight the flammable methane which
existed naturally within the mine. Without the new lamp, mining operations were
deadly and many workers died.
improvements saved countless lives in dangerous industries and minimised injury
even more. For modern offices and businesses, the story was different. It
wasn’t until the invention of electricity that the world of work changed
The largest improvement in the evolution of lighting came from the invention of alternating current. The Great Barrington demonstration project showed this. Suddenly, 23 businesses could be powered from one transformer which led the way to cheaper lighting for entire city streets.
electricity was made available to homes and businesses on a city level,
traditional methods of illumination slowly lost their market share. They
weren’t a viable option anymore after 1880 when Thomas Edison patented a bulb
that could last for 1500 hours.
Slowly over the
20th century, the lightbulb developed to become more efficient. With the
creation of fluorescent bulbs, a single lightbulb could last for over 10 years
of regular use.
efficient bulbs were invented, it wasn’t until the development of LEDs that
lighting could be produced easily and effectively for all uses. LEDs, or
light-emitting diodes, are in almost every device now. At their smallest size,
they can be smaller than a single grain of salt.
For modern use,
workplaces rely on LEDs to light an entire building. They last for up to 25
years, making them more cost effective than traditional incandescent
The first yellow
LED was invented in 1927 and other colours were invented over time. Blue LED
lights weren’t invented until 1994 and an LED replacement for incandescent
bulbs didn’t exist until 2011. Now that we have LED filaments, the original
bulb was withdrawn from sale in the UK and it has stopped being used in modern
One of the most
important features of LED lights is its versatility. Although one LED may only
be a few lumens, they can meet any need for indoor and outdoor use when many
are combined together as one light source. Depending on the casing, an LED
light can be fully submerged underwater.
light from gas lamps for a small factory previously required 1,000 individual
sources but that same amount of light can be produced by just one or two LED
lights. Some directional lamps, such as our Mozart Architectural LED light,
produce 40,000 lumens which illuminate buildings and bridges at long distance.
workplaces, the most important factor to consider is a natural feeling source
of light. Employees love to be able to see daylight but unfortunately some
building designs and layouts make that near impossible. Choosing an LED panel,
such as our office lights, provides a flicker and glare free lighting solution
that minimises mid-day drowsiness in difficult corporate settings.
To choose the
right solution, consult both your employees and health and safety regulations.
Modern offices can’t use antiquated solutions for the good of their workers and
of their budget. Different industries benefit from different installations,
such as hanging bay lights for high ceiling industrial factories.
