True, those tiny metal fittings may seem fairly insignificant due to their size but their significance is that they dictate that bulbs can be fitted to that light fittings. Without the right cap, the room, alleyway, stairwell or backyard will stay in the dark.
With the range of lights that can be found on the market today, there are very definite specifications to make sure the right bulb is fitted. By way of example, both pin, or bi-pin, the cap on some lights can only be placed in bi-pin light sockets, so gu10 LED bulbs can’t be set in a light socket that isn’t meant for the gu10 cap. However, there is more than one kind of bi-pin cap, with the cap on g9 halogen bulbs considerably different in design and appearance, and used exclusively with certain types of halogen bulbs.
The reason for a cap is to allow electrical contact between the electrical supply and the light itself, without leaving wiring and electronic elements vulnerable. The metallic pins make immediate contact with the electricity supply, allowing the electricity to flow through the filament, producing the necessary energy to create the light to glow and supply the required illumination.
