Our best low energy light bulb!Using the latest in LED filament technology, Crompton Lamps have released one of the UK's most energy efficient light bulb ranges yet. Designed to surpass all requirements of the new ERP energy requirements; these energy saving bulbs achieve the highest A rating possible with an amazing performance of over 210lm/W - meaning these low wattage light bulbs are more than 60% more efficient than regular LED light bulbs.At only 2.2W, this LED GLS light bulb could be one of the best LED light bulbs released to the market to date. It has been developed by Crompton Lamps as the most efficient way for replacing traditional incandescent light bulbs.Each light bulb in the range delivers massive cost savings due to it's low energy coupled with the same retro styling of old style light bulbs.These ultra efficient light bulbs utilise 4 LED filaments, resulting in a gorgeous, traditional aesthetic that belies the light bulb's ultra-modern specification.

They output a relaxing 3000K warm white colour with great colour rendering and no colour casting (as seen in the first generation of ultra-efficient LEDs).Whereas a traditional light bulb might use approximately 40W to produce 470 lumens, these ultra LED GLS light bulbs use just 2.2W.Coupled with the light bulb's vastly superior lifetime of 50,000 hours - these energy efficient bulbs have the potential to last for many years to come and can reduce your lighting bills by up to 95%.This light bulb's 60mm diameter GLS shape and BC-B22d bayonet (22mm) cap will enable them to retrofit directly to any existing fitting designed to accept standard sized light bulbs.With electricity being one of the biggest household costs, finding simple swaps to reduce this energy consumption can have real impact on your cost of living. Low wattage LED bulbs are a brilliant alternative to traditional incandescent or halogen bulbs. Choosing the best energy saving light bulb can contribute to cheaper utility bills, as well as help you to reduce your carbon emissions by up to 40kg a year.
