![]() ![]() Most modern dimmer switches should work with CFL bulbs, although some older ones might not be compatible. Some CFLs take a few minutes to reach full brightness. Through this method, less energy is lost to heat and the bulb is more energy efficient. ![]() CFLs typically use 60-80% less energy than incandescent lights.ĬFL bulbs use an electric current to excite gases within the bulb, causing a phosphorus coating on the inside to glow, producing light. The colour temperature and colour rendering index (CRI) can vary more than with traditional light bulbs.Įnergy saving bulbs, also known as compact fluorescent lamps (or CFLs) were the original energy-efficient alternative to incandescent bulbs. It's tricky to get a consistent look in your home if you mix different LED brands and types.The packaging should say whether LEDs are dimmable. To dim them, you might need to upgrade to a dimmer that recognises low electrical loads.Some people don't like the quality of light given out by LED light bulbs, as they can produce a cooler, bluish light.They give out light almost instantly when you flick the light switch, so you don't have to put up with dim light while your LEDs get going.They last for 25-30 years, depending on which ones you buy and how you use them.LEDs use 90% less energy than traditional incandescents, and can sometimes pay for themselves through energy savings in just a couple of months.While the brightest bulbs can still set you back around £20, most cost less than £10, and the energy savings they provide make them well worth considering. Plus, prices are getting lower all the time. LEDs also have a significantly longer lifespan than halogen and CFL light bulbs, estimated at around 25,000 hours compared to 2,000 hours for halogens and 10,000 hours for CLFs. They are the most energy-efficient option, using 90% less energy than traditional incandescent bulbs, which were phased out in the UK in 2009. They produce light through the use of a semi-conductor that emits light energy when an electrical current is passed through it. LED lights use very little energy, are claimed to last a very long time and, unlike regular energy-saving bulbs, are instantly bright when switched on. ![]()
