Energysaver bulbs7/2/2023 ![]() When it did come on, it took a few more seconds to achieve full brightness. You might remember them as that spiral shaped tube bulb that had a slight delay between flicking the switch and the light coming on. Compact fluorescent light bulbsĬompact fluorescent light bulbs, or CFLs, were the first real energy saving light bulbs to replace incandescents. The sale of halogen bulbs has been banned since September 2021 5. That’s because of their halogen gas content, which makes them about 3 times more efficient than incandescent bulbs. They use less energy and last longer than traditional incandescents. Halogen light bulbs were invented in the mid-1950s. In fact, the EU started to phase them out 4 as early as 2012. We’ve seen how inefficient incandescent bulbs are. Looking for light bulbs that can do even more? Read our guide to smart light bulbs, how to choose them, and how you can control them remotely. But energy saving bulbs improve on this, by varying amounts. Incandescent bulbs are simply not energy efficient. It’s astonishing to know that only 10% of the energy used in traditional incandescent bulbs is converted to light. What happens to the energy wasted by the light bulb? The Energy Saving Trust says that for every 60 watt bulb in your home, you could save up to £3 per bulb per year (based on a 660-lumen bulb running for 445 hours a year 2). Lighting makes up around 15% of the average home’s electricity bill. That’s around the same amount of emissions as driving your car 140 miles 1. The Energy Saving Trust has worked out that if you replaced all the bulbs in your home with LED bulbs, you could reduce your carbon emissions by up to 40kg a year. Using less energy means you’ll save money.They use less energy and so reduce your carbon footprint.Making a switch to energy saving bulbs can make a big difference in 2 ways: So, an energy saving bulb uses less electricity to emit the same amount of light as a traditional bulb. What are energy saving light bulbs?Įnergy efficiency is all about squeezing out every last bit of power, and not letting any go to waste. And that generates lots of carbon emissions. Why? Mainly because these old fashioned filament light bulbs use a lot of energy. But, as energy efficiency plays an increasingly important role in our lives, we’re looking at alternatives to Edison’s original incandescent bulb. Without the humble light bulb, life would be dark, dismal, and downright inconvenient. We have a lot to thank Thomas Edison for.
