GLS

GLS (General Lamp Service) bulbs are quite commonly found in many light fittings, especially outdoor lights, flush fittings and table lamps. GLS bulbs have the traditional bulb shaped glass encasing the LED chips inside. A 60-watt LED equivalent is 7-9 watts. A 100-watt incandescent bulb produces 1600 lumens of light, while a 12-14 watt LED gives off the same.
