Love Energy Savings Guide to Low Energy and LED Lighting
Continuing with or renewable energy theme here at Love Energy Savings, we have put together the following guide to low energy and LED lighting. You may well have seen our recent guides on biomass boilers, heat pumps, voltage optimisation, solar electricity and solar water and this is the final instalment of a bumper few weeks for renewables at the Love Energy Savings Help Centre.
So, what are the benefits of low energy and LED lighting?
- Low energy and LED technology can reduce your lighting related energy usage by around 90%.
- Maintenance costs are dramatically reduced once LED unites are installed in the home or business.
- LED lighting will pay for itself within 6 and 36 weeks depending on the size of the property and usage levels.
- Energy saving lighting can remain active for a staggering 100,000 hours, which really puts power hungry conventional lightbulbs to shame.
- Modern LED and low energy lightbulbs are now very high quality and can provide a great standard of light. This can help to boost productivity and employee morale and also help to meet health and safety guidelines.
What’s The Problem with Incandescent Light Bulbs?
We’ve had energy saving lightbulbs in the UK for decades now and they have grown in popularity steadily in that time, despite many businesses not being keen in their less than aesthetic appearance. Advances in manufacturing techniques as well as increased efforts by companies in the UK to up their efforts with renewables have seen their use boosted a great deal. But what exactly makes them so good when compared with their incandescent counterparts?
Old fashioned lightbulbs work by passing an electric current through the filament you can see in the centre of the bulb. This filament becomes red hot and generated the light which is then emitted around the room.
The problem with this concept is that the majority (around 90%) of the energy produced is wasted as heat making them ridiculously energy inefficient. The amount of electricity that they waste is remarkable given how we are all trying to up our green energy efforts, spurring the government to ban the sale of incandescent lightbulbs over 40 watts to homeowners. Unfortunately, the same cannot be said of business energy customers and there is still a great deal of electricity being wasted across the United Kingdom. .
Are All Energy Saving Lightbulbs The Same?
Nope. As mentioned before there have been energy saving lightbulbs of sorts available for some years now but they have come on considerable since the ugly spirally things you may remember (although even these are far better than incandescent light bulbs).
All energy savings bulbs work on the premise of converting more energy straight into light rather than heat and therefore using far less power. The more modern approach to this is LED (light emitting diode) lighting and the dated version is CFL (compact fluorescent lighting) and we stress again that either are preferable to standard light bulbs. When given the option however, businesses in the UK should most certainly be looking to adopt LED lighting in their premises, in the interests of their bottom line and the environment.
LED Energy Savings Lightbulbs
These devices are made using many different light emitting diodes which together provide enough photons to light the room. LEDs are referred to as “solid state” lighting as it is emitted from a block object instead of the glowing filament you see in a traditional lightbulb.
These bulbs are so efficient because they do not need to create immense amounts of heat in order to produce light. Instead, just a small current is necessary making them far more efficient than halogen or incandescent lighting. Whereas these dated devices will light a room for around 1,000 hours, LED energy saving lightbulbs have an estimated lifespan of 40,000 hours making them ideal for workplaces that require the lights to be on all the time. Ultimately, LED energy savings lightbulbs require just 10% of the electricity used by halogen or incandescent bulbs and produce exactly the same, if not better amounts of light.
Did You Know? Just changing one 50 watt incandescent lightbulb in your home or business with an LED version, could save you around £15 per year. If you think about
CFL Energy Saving Lightbulbs
The older energy saving lightbulb, the CFL , is still a good option compared with incandescent and similar. These use an inert gas to generate power and phosphor covers the inside layer of glass. When you flick the switch, UV rays then cause this phosphor to light up and glow and this provided light. This takes a little while which is why you will often notice them getting brighter and brighter for the first five minutes or so. CFL energy saving bulbs are not quite as effective as LED lighting but still only use 20% of the electricity used by standard bulbs. You will usually get around 10,000 hours out of a CFL bulb which is a whopping ten times more to what you are currently likely to be using.
The only nasty thing we can think to say about CFL energy saving light bulbs is that they contain trace amounts of mercury, which can be bad for the planet. However, as long as these lightbulbs are disposed of appropriately, this will not create an issue. CFL bulbs are a perfect replacement for incandescent lightbulbs in any office, workplace or home that can’t quite afford LED alternatives.
Lower Your Energy Bills Immediately
Essentially, the installation of energy saving lightbulbs whether it be LED or CFL is a quick and easy way to lower your business or domestic energy bills right away. You will instantly lower the amount of power you are using on lighting by 80-90% and you can then look into getting onto a cheaper tariff to make further savings. You can do that right away by using our free, no-obligation energy comparison engine which will find you the cheapest gas and electricity rates at the click of a button. By tackling energy efficiency and your tariff at the same time you are adopting a double pronged attack on your energy bills and over the year you can make some rather remarkable savings.
