General Lamp Service (GLS) bulbs relate to the traditional light bulb shape. Since their invention in the early 1800s, GLS bulbs haven't changed much and can be used in most light fittings. Our LED GLS bulbs are available with an E27 (screw-in) or B22 (twist-in) cap and are perfect for table lamps, floor lamps and ceiling lights. Available in different colour temperatures from cool white to warm white, find a LED GLS bulb to cast the perfect hue over your room. Plus, with all the benefits of LEDs, they save you money and energy too. Find out more about how LED bulbs can save you money in our Guide to Energy-Saving LED Light Bulbs, or for more options, browse our decorative LED bulbs.
