The E27 LED Cob Filament Bulb is the next generation in lighting, combining the rustic look & high quality light of traditional incandescent bulbs with the energy saving qualities of warm white LED's. Stylish light features are ruined by the bulky & awkward appearance of traditional energy saving light bulbs, however the E27 LED Cob Filament Bulb uses strips of LED light to recreate the exposed filament appearance of traditional incandescent bulbs. Designed in a similar manner to squirrel cage bulbs, the exposed filament design works especially well in industrial style lighting & modern light fixtures where the bulb is exposed, as well as enhancing the design of more traditional lamps.
