When it comes to eco products, the ones that most of us are familiar with and that seem to get the most attention are energy saving lightbulbs. Energy saving lightbulbs are bulbs that require less energy in order to light up the same sized room adequately which is of course eco friendly as it means that you aren’t using up as much electricity (and so you are contributing less to the amount of fossil fuels burned) as well as being a great way to save money as you will be charged less by your electricity supplier. But how do these eco friendly light bulbs work? And what is different about them that means they won’t use up as much energy?
Interestingly, the differences between energy saving lightbulbs and ‘regular’ lightbulbs is quite great and the two are fundamentally different. This is because energy saving lightbulbs are fluorescent while ‘regular’ lightbulbs are incandescent. One major difference between these too which of interest for those going green is that incandescent bulbs come with different wattage outputs and typically these will be 40, 60 or 100 watts. For going green this is useful to know as this number reflects just how much energy your light bulb will be using every hour. So the higher your wattage the more power you are using – if you’re not ready to switch to energy saving lightbulbs then you should at least use a lower wattage where possible and bear this in mind when buying lamps.
Now with energy saving lightbulbs this is even more eco friendly. These work via the tubes they have which are filled with mercury vapour gas and a phosphorous coating. The electricity then sends a charge through this which makes the mercury vapour give off ultra violet light in turn stimulating the phosphorous coating to give off ‘regular’ light. In other words, a reaction is taking place inside the tubes which means that unlike regular lightbulbs there is no need for large amounts of power to create the light.
This is far more eco friendly of course and that means that buying energy savers is great for going green. At the same time they can be fitted into most regular lamps so anyone can use them, and they’re a great investment as though they are slightly more expensive to buy in the first place they will last much longer than regular bulbs.
