![]() ![]() This method means less energy is lost to heat and the bulb uses less energy overall. Instead they use an electric current to excite gases within the bulb that then cause a phosphorous coating on the inside to glow, producing light. Old-style incandescent bulbs had a filament inside that was heated until it glowed, which meant they used up energy to generate heat. Manufacturers will gradually stop producing CFLs as more buyers transition to LEDs. With the government looking to remove 'high energy' fluorescent lights from shelves from 2023, and an increasing industry focus on the move to LEDs, we anticipate that CFLs will gradually become harder to find. CFLs typically use 60-80% less energy than an incandescent, while halogens use 20-30% less and LEDs use an astonishing 90% less. The Gov.uk website says these labels will 'raise the bar for each class, meaning very few bulbs will now be classified as A, helping consumers choose the most environmentally friendly bulbs.' CFL light bulbs explained What are CFL light bulbs?Ĭompact fluorescent lamp (CFL) light bulbs are the original energy efficient alternative to now-defunct traditional incandescent bulbs. To help consumers understand the benefit of replacing halogens and fluorescent light bulbs with the most energy efficient alternatives, all new light bulbs will be sold with updated energy labels on their boxes.Ī new simpler scale, running from A to G, will replace the old (and slightly bewildering) A+, A++ and A+++ ratings. ![]() There's a chance you'll find a couple of dusty halogen light bulbs still on sale at your local DIY store, but retailers will no longer be able to buy new stock once shelves are empty. Additional figures claim that around two thirds of bulbs sold in Britain are LED lights and that, while they produce the same amount of light, these last 'five times longer' than traditional halogen light bulbs. We recommend opting for LEDs where possible, as they'll be sticking around for years to come.Ī post on Gov.uk notes that a shift to LED bulbs 'will cut 1.26 million tonnes of CO2' – the equivalent of removing more than half a million cars from UK roads. However, we expect that manufacturers will stop producing them over the coming years, regardless of any ban, as their focus shifts to LEDs. The plan is to start removing these lights from retailer shelves from September 2023, and there's now a good range of LED strip-light alternatives.Ĭompact fluorescent lamps (CFLs) are low energy bulbs (although not as low as LEDs), so don't appear to be part of the planned ban. The government says 'high energy' fluorescent lights (including traditional, tube-style fluorescent lights commonly found in offices) will follow suit. In October 2021, the UK government banned the sale of halogen light bulbs in an effort to 'cut emissions and save consumers on their energy bills'. Old-style 'high energy' incandescent bulbs stopped being sold in the UK from 2009, but they're not the last light bulb to face the chop because of their relatively poor energy efficiency. ![]() The phase-out of halogen and fluorescent light bulbs Our table shows at a glance how these light bulb types compare for lifespan, typical cost and energy use – we delve into more detail on the pros and cons of each type later in this article.
