Energy Efficient Dimmer Light Bulbs – The caps that sit on the foundation of a light bulb are equally as crucial as the bulb. True, those little metal fixtures may seem rather insignificant due to their size but their importance is that they dictate which bulbs may be fitted to which light fixtures. Without the right cap, the room, alleyway, stairwell or bathtub will stay in the dark.
With the range of lights that can be found in the marketplace today, there are very definite specifications to make sure the right bulb is fitted. For instance, both pin, or bi-pin, the cap on certain lights can only be put in bi-pin light sockets, therefore gu10 LED bulbs cannot be placed in a light socket which isn’t designed for your gu10 cap. But, there’s more than one kind of bi-pin cap, with the cap on g9 halogen bulbs considerably different in design and appearance, and utilized only with particular kinds of light bulbs.
The reason behind a cap is to permit electrical contact between the electric supply and the light itself, without even leaving wiring and electronic elements vulnerable. The metallic pins make direct contact with the power supply, allowing the power to flow through the filament, creating the essential power to cause the light to glow and supply the required 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 arguably the most recognizable cap and is more often than not found on the ordinary incandescent bulbs choice for national lighting, though energy saving lighting also feature this cap to permit simple switch over to greener home lighting.
The design is a simple metallic cap at the bottom of the bulb with 2 ears, or tiny pins, protruding from the side. These two pins lock in the face of the socket, to hold the bulb in place. The title bayonet is derived from the thrust and twist action that’s necessary to fit them.
