How LED’s can be an environmentally sympathetic choice…
While there are many forms of lighting available today, LED’s (or light emitting diodes) are considered by many to be the most energy efficient and environmentally friendly option when it comes to lighting.
As heritage experts, we are very fond of gas lighting and the role it has played, and continues to play, in particular projects and pieces. However, when it comes to electric lighting, we can’t ignore the opportunities of LED as an alternative to traditional electrical discharge lamps. Here’s the low down on why LED is a sustainable and environmentally solution, and why you could consider it.
LED’s are designed to last a lot longer than traditional light bulbs. LED’s can last up to 20 times longer than standard incandescent bulbs or halogens. This fact alone means that less bulbs need to be manufactured as replacement can be made much less frequently. The impact on the environment via manufacturing, packaging and transport is therefore much reduced.
One reason LED bulbs are more sustainable is because they can offer 80% more energy efficiency than standard light bulbs. According to UK Energy Lighting, fluorescent lights only convert 5% of the energy they use into light, and 95% into heat. However, LED is the reverse; they can convert 95% of the energy they use into light and approximately 5% into heat meaning they require a lot less power to provide the same output. There is an environmental impact but also a monetary one; LED can be much cheaper to operate than standard light bulbs.
Traditional light bulbs can contain chemicals such as mercury. When traditional bulbs are disposed of, chemicals contained inside can filter down into the soil and have a harmful effect on the environment and wildlife. To avoid this environmental damage, traditional bulbs need to be disposed of by a specialist waste carrier. There will, sadly, therefore be times when proper processes aren’t carried out and the environment suffers as a result. LED’s are more environmentally friendly as they do not contain these toxic chemicals so specialist disposal isn’t required. There are two impacts of this – one is the lack of toxic chemicals being used, and one is the reduction in transport emissions that specialist waste carriers produce.
What to consider when buying lighting
A newly commissioned, or refurbished light fitting can have many purposes. From private residential lighting, to commercial spaces, to gardens, public realm, streetlights and much more. There’s a lot to consider and it’s critical to get the right look, and light source, for the setting.
When it comes to making environmentally friendly lighting choices, there are some simple things to consider that can make a big difference!
- Source efficacy – how efficient is the LED device itself?
- Luminaire efficacy – how well does the light fitting and light source work together? Does the design of the lantern allow the light source to provide the required output?
- Power – how much electricity will be needed to power the light? Generally speaking, an LED can last more than 25 times longer than a traditional bulb.
- Maintenance – does your light fitting have easy access for maintenance? And do you have the specialists you need to take care of this element?
