Pure has announced that its "Energy Saving Recommended" radios are officially certified to use less energy than an energy saving light bulb.

According to the Energy Saving Trust, "running four Pure Energy Saving Recommended radios will use less electricity than one low energy light bulb on for the same time".

Adrian Arnold, the Energy Saving Trust's "energy doctor" says: "An Energy Saving Trust accredited digital radio is the most efficient way to listen to DAB digital radio and we would encourage anyone enjoying the fantastic content that digital radio provides to move across to one of these radios which uses less electricity and is better for the environment".

Anyone on the look out for a green radio should note the list of ten Energy Saving Recommended accredited Pure radios that include the Move, EVOKE-1S, Siesta, Chronos II, TEMPUS-1S, ONE Mini, ONE Classic, ONE Elite, EVOKE Mio and EVOKE-2S.
