We pay them very little attention until they go out. We feel cheated when we have to make a supermarket run dedicated to them and we certainly get frustrated when we buy the screwy one instead of the clippy one. These issues are basically eradicated when changing to. Besides their clear economic benefits and longevity, LED light bulbs trump halogen lights in all departments. Here are just a few qualities that make LED’s the clear solution in sustainable lighting.
Most of us are under the impression that if we’ve changed from halogen to Compact Fluorescent Lighting (CFL), we can be secure in the knowledge that we’re living under the “greenest” light there is. That was the case some time ago, before LED lights saved the day, even though CFLs themselves have come a long way since being introduced to the market.
The Past (CFL)
- A wider range of light temperatures
- Longer lasting than halogens (lamp life of approximately 10 000 hours)
- More energy efficient
- Use approximately 80% less energy than a halogen equivalent.
- A lot of energy and materials are used in the manufacture of CFLs.
- The mercury content of one CFL is enough to pollute 30 000 litres of water and presents a high risk factor if broken.
Then came along LED lights. These lights have made improvements on all of the above positives as well eliminated the issues of the CFLs.
The Present and Future (LED)
LED lights have been touted as an inevitable replacement for halogen and CFL lights. It’s hard to find any reasons not to introduce LED lights as a home or office fixture, so here are some figures illustrating the benefits.
- LED light bulbs expend 65% – 85% less energy than regular light bulbs.
- A family of four people could typically spend around R500 per month on lighting.
- Implementing LED lights will reduce this lighting cost to just R150 per month resulting in a R350 saving each month.
- Converting that “typical” household from conventional lighting to LED lighting could cost somewhere around R5 000.
- Although initially this figure might see intimidating, under closer inspection it’s clear that your monthly savings result in your investment in LED lights taking only 1.5 years to payback.
- Once you have reached this payback point, lighting will only cost you in the region of R150 per month until the lifespan of your LED lights has come to an end. LED lifespans can last for 15 years depending on usage. Most warranties on LED bulbs is between 30 000 and 80 000 hours.
It’s a rather convincing victory for LED lighting. Uses for LED lights are extensive and are made for all common fittings, from Edison to Bayonet and are being employed more often in large-scale illumination, including lampposts, aviation and aquarium lighting. A large part is to do with the lack of heat emitted from the lights. LED lights are clearly the way forward. Whether you’re in big business, needing instant activation tube lights or at home with a penchant for top lights, LED bulbs or fairy lights – LED is the way to go.
