12 Volt E26 Base Led Light Bulbs – The caps that sit on the foundation of a light bulb are equally as crucial as the bulb themselves. True, those little metal fittings may seem fairly insignificant given their size but their significance is such that they dictate which bulbs can be fitted to which lighting fittings. Without the ideal cap, the space, alleyway, stairwell or bathtub will stay in the dark.
With the selection of lights that can be found on the market today, there are very definite specifications to ensure that the ideal bulb is fitted. By way of example, both pin, or bi-pin, the cap on certain lights can only be put into bi-pin light sockets, therefore gu10 LED bulbs can’t be placed in a light socket that isn’t designed for the gu10 cap. However, there is more than one kind of bi-pin cap, together with the cap on g9 halogen bulbs significantly different in appearance and design, and utilized only with particular kinds of halogen bulbs.
The main reason for a cap would be to allow electrical contact between the electrical supply and the lighting itself, without even leaving wiring and electronic aspects exposed. The metal pins make immediate contact with the power supply, allowing the power to flow through the filament, producing the necessary power to create the light to glow and provide the required illumination.
The entire selection of caps is extensive, but they are sometimes divided up into three main kinds, namely the bayonet, the Edison screw and the bi-pin. |} Bayonet Cap That is potentially the most recognizable cap and is more often than not found on the normal incandescent bulbs selection for domestic lights, though energy saving lights also feature this cap to allow easy switch over to greener home lighting.
The layout is a simple metallic cap at the base of the bulb with 2 ears, or tiny hooks, protruding from the side. Both of these pins lock at the side of the socket, to hold the bulb in place. The title bayonet comes in the thrust and twist action that is needed to match them.
