What we call a light bulb, is referred to as a lamp by the lighting industry. Compact fluorescent lamps (CFLs) are low energy light bulbs. Compact LED bulbs can look very similar to CFLs, this means you can change to LEDs without having to change your light fittings. CFL’s use up to 80% less energy than old fashioned incandescent bulbs, but to do this, they need a small amount of mercury which is why they can’t be thrown away in your Kerbside bins.
The typical amount of mercury in a lamp is between 1.2 to 4mg, and in a domestic compact florescent lamp (CFL) this equates to the tip of a ballpoint pen. The mercury in one CFL is not enough to pose a health risk but they do need to be disposed of responsibly to reduce the risk of large quantities of mercury ending up in landfill.
In the UK, the collection and recycling of fluorescent lamps is compulsory under the Waste Electrical and Electronic Equipment (WEEE) Directive. If we all recycle, we can protect our environment, and the mercury, glass and metal can be reused. If you want to know how, have a look at: www.recolight.co.uk How can we recycle? Save up your light bulbs and tubes and take them with you next time you are making a journey to your council recycling centre (AKA The Tip!).
Some electrical retailers offer a recycling service. Robert Dyas is one, but I am sure there are others. When you buy your next light bulb do ask if they offer a recycling scheme.
