This 110V LED GLS light bulb is designed for use in industrial applications where a full 240V mains voltage is either unavailable or unsuitable for use. It is not designed to run on mains voltage circuits.The LED GLS light bulb\'s universal shape enables this LED version to retrofit directly into existing fixtures with minimum effort. It is distinctly more efficient than the incandescent versions it is designed to replace, consuming only 9W of power yet producing light of an equivalent brightness to 60W filament light bulbs. This remarkable efficiency - when considered alongside each light bulb\'s vastly improved longevity and reliability - can potentially reduce your lighting bill by up to 90% whilst simultaneously reducing carbon emissions.A thermal plastic shell encases the light bulb and dissipates heat away from its components more effectively than existing materials, thereby extending its longevity even further. This results in a range of light bulbs that is reliable, green, elegant and easy to install.Not suitable for dimming. Opal finish with site safe yellow body. Suitable for inspection light bulbs.
