GLS Lamps

Shop GLS lamps at RS Electrical Supplies. GLS — short for General Lighting Service — is the classic pear-shaped light bulb, the most recognisable lamp shape in the world. Modern GLS lamps use LED technology to replicate the warm, omnidirectional light output of traditional incandescent bulbs while consuming up to 90% less energy and lasting significantly longer. Available in B22 bayonet cap and E27 Edison screw fittings to suit all standard UK pendant lights, table lamps, and ceiling fittings.

GLS Lamps Available

• LED GLS B22 (Bayonet Cap) — the traditional UK bayonet fitting; direct LED replacement for standard incandescent GLS bulbs
• LED GLS E27 (Edison Screw) — large screw fitting for pendant lights, floor lamps, and decorative fittings
• Dimmable GLS lamps — compatible with leading and trailing edge dimmer switches; check dimmer compatibility before purchasing
• Non-dimmable GLS lamps — for standard on/off switching circuits
