Wood Effect Laminate Flooring For Bathrooms – The caps that sit on the foundation of a light bulb are just as crucial as the bulb themselves. True, those tiny metal fittings might appear fairly insignificant given their size but their significance is such that they dictate which bulbs may be fitted to which lighting fittings. Without the ideal cap, the space, alleyway, stairwell or backyard will stay in the dark.
With the range of lights available on the market today, there are very definite specifications to make sure the ideal bulb is fitted.

However, there is more than one type 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 light bulbs.
The reason behind a cap is to allow electrical contact between the electric supply and the lighting itself, without even leaving wiring and electronic elements vulnerable. The metal pins make immediate contact with the power source, allowing the power to flow through the filament, producing the essential energy to cause the light to glow and supply the necessary illumination.
The entire range of caps is extensive, but they are sometimes broken down into three principal types, namely the bayonet, the Edison screw and the bi-pin. |} Bayonet Cap That is arguably the most recognizable cap and can be more often than not found on the normal incandescent bulbs selection for domestic lights, although energy saving lights also contain this cap to allow easy change over to counter house lighting.
