There is always a lot of speculation over whether or not energy saving light bulbs actually do what they’re named to do; save you energy! With the increase in climate changes and global warming, it is becoming more and more essential to do what we can to prevent climate change from worsening and to protect our world from any further destruction.
An energy saving light bulb, or a compact fluorescent light bulb as it is also known was originally designed to replace incandescent bulbs which have previously been banned for not being energy efficient enough. CFL’s used a tube which is curved and folded to fit into the same space of an incandescent bulb.
There is a saying that says if you want to change the environment start by changing a light bulb; now one might think that this is ridiculous and wouldn’t actually work but you can’t knock or question figures… A study has been carried with results which suggest if every household changes just 1 light bulb to an energy saving one, we would save £1,300 billion pounds! It would also save the equivalent of taking 7.5 million cars off the road. To think of it in numbers like that, you just simply can’t argue it!
Many can be sceptical because the price of the bulbs to buy initially is actually higher which can put people off to begin with, but over the course of their lifetime, each bulb can actually save over 5 times their original purchase cost. To mention even more savings, an energy saving bulbs lifetime in comparison to an incandescent bulbs is 12 times longer! Incandescent bulbs lifetime is usually 750-1000 hours which is the equivalent of 5 months use, CFL’s can last up to 6 years. Just think of all the savings!
You may be thinking, but if they save energy and money they must be compensating somewhere for it – maybe they don’t have the same brightness of light or even the same colour of light. I’m sorry but at the same time very proud to say that they give off the same amount of light! When buying an energy saving bulb, just make sure you look out for lumen rating! This is the rating which indicates how much light a bulb gives off. The wattage of a CFL is usually a quarter of that of an incandescent bulb; for example, when you are looking for a 60W bulb, it will most likely be a 15WCFL lamp you will be wanting.
With regards questioning whether or not they have the same colour temperature of light, yes they do! CFL’s are available in the same amount of variations, sizes and shapes as incandescent bulbs – so much so they are even available to be purchased in dimmable and have the options of indoor or outdoor lighting! In fact, when Tony Blair was Prime Minister, he made a statement of using a CFL in the outdoor light of 10 Downing Street to show that even the government was making an effort to save our world physically too.
Sadly, yes there is a negative of compact fluorescent bulbs, which is because of their design, the way they work and are made the bulbs contain mercury. Mercury is a toxic heavy metal which can cause serious health problems if it is inhaled or ingested in large doses or over long periods of time. CFL’s only contain 5mg of mercury and when the light is in use this wouldn’t be inhaled so there is no fear for harm, but obviously it is recommended that these bulbs are recycled to prevent any toxicity leaking into landfills and causing the damage we are trying to prevent from using them. This seems like such a small price to pay though for saving so much money elsewhere! The fact that these bulbs have to be recycled almost didn’t feel like it was worth a mention!
So to recap;
- CFL’s use two thirds less energy than standard incandescent do.
- They provide the same amount of light and can last up to 10 times longer.
- 70% less heat is generated from CFL’s which makes it safer to operate.
So what are you waiting for? Switch to energy saving bulbs, save money, energy and help the environment!
