If you desire the look of days gone by, but want the technology to be firmly rooted in the present, the Osram 4.8W dimmable GLD LED light bulb is for you.These LED filament bulbs are the smart choice for your home with their energy saving potential, their elegant design and their warm, cosy light. They truly stand out in minimalistic fixtures but will naturally compliment any kind of lighting design.The tungsten filaments found in these older light bulbs have now given way to four LED filaments, resulting in a gorgeous, traditional aesthetic that belies the light bulb\'s ultra-modern specification. These filaments, albeit similar in appearance, are much more efficient and robust than their traditional counterparts. Where a traditional incandescent GLS light bulb would use 40W to produce 470 lumens, these energy efficient modern LED light bulbs use just 4.8W. This, coupled with the light bulb\'s vastly superior 15,000 hours long life, has the potential to reduce lighting bills by up to 88%.Hung from the ceiling in exposed clusters or used in singular, shaded fittings, these filament light bulbs manage to be both simple and sophisticated with the raw beauty of the LED filament elevated to the fore of their design.The light bulb\'s standard GLS shape and ES-E27 Edison screw (27mm) cap enable the light bulbs to retrofit directly to any existing fitting designed to accept light bulbs.240V 4.8W (40W equivalent) LED GLSES-E27 capYes - Dimmable2700K Warm White colour470 lumens
