These Capsules are frequently used in G9 adaptors to suit Candle, Golf Ball and GLS lamps and are popular with domestic users because they allow retention of a traditional light bulb shape. Benefits include: full dimming capability, 30-40% energy saving over an incandescent and a small carbon footprint as a result of reduced waste material for disposal. Identify this type of Capsule by measuring 9mm between the pins.
