Wood Floor Without Vapor Barrier – The caps that sit on the base of a light bulb are just as important as the bulb. True, those tiny metal fixtures might appear fairly insignificant due to their size but their significance is such that they dictate which bulbs can be fitted to which lighting fixtures. Without the right cap, the room, alleyway, stairwell or backyard will stay in the dark.
With the range of lights available on the market nowadays, there are quite definite specifications to make sure that the right bulb is fitted. For instance, the two pin, or bi-pin, the cap on some lights can only be put in bi-pin light sockets, therefore gu10 LED bulbs can’t be set in a light socket that isn’t meant for the gu10 cap. But, there is more than one kind of bi-pin cap, together with the cap on g9 halogen bulbs significantly different in design and appearance, and used only with particular kinds of halogen bulbs.
The main reason behind a cap is to permit electrical contact between the electrical supply and the lighting itself, without even leaving wiring and digital elements vulnerable. The metal pins make direct contact with the power supply, allowing the power to flow through the filament, creating the necessary energy to create the light to shine and supply the necessary illumination.
The full range of caps is extensive, but they can be broken down into three principal types, namely the bayonet, the Edison screw and the bi-pin. |} Bayonet Cap This is potentially the most identifiable cap and can be more often than not discovered on the ordinary incandescent bulbs selection for domestic lighting, though energy saving lighting also feature this cap to permit easy change over to counter house lighting.
The layout is a simple vertical cap at the bottom of the bulb with 2 ears, or small pins, protruding from the side. The name bayonet is derived from the thrust and spin action that is needed to fit them.
