This elegant 4W LED ST64 smoked glass light bulb from Osram offers all the benefits of LED technology with the vintage style of the classic LED ST64 Edison shape. Its LED 'filaments' are housed in a smoked glass envelope and recreate the look of Edison light bulbs. They looks great either hung exposed in clusters, or used in a vintage floor or table lamp. While it might look like an incandescent light bulb, its performance is far more efficient. The 4W squirrel cage light bulb emits 140 lumens of extra warm white 1800K light, perfect for decorative lighting in homes or as accent lighting in commercial spaces such as bars and restaurants. Its long 15,000 hour life means that once the light bulb is installed, it will be years before it needs replacing again. The ES-E27 Edison screw (27mm) cap retrofits to existing light fixtures, making installation quick and easy.
