PAR 20 BULBS
The most widely used form of the PAR 20 bulbs is the halogen bulbs. PAR20 halogen light bulbs have a halogen capsule light in a small reflector as result they  give a great amount of light output, along with that they deliver good beam control. There are wide verities of PAR20 lamps including many wattages and several beam spreads. Halogen bulbs are incandescent bulbs Halogen bulbs, however, are filled with a special gas that actually rebuilds the filament and provides longer average life spans than normal They come in different shapes and sizes for various different uses. PAR stands for parabolic aluminized reflector. These types of bulbs will provide you with a high light output, a more white-colored light and longer life than normal. That is the main reason why the halogen are many times used in energy saving lighting situations. The PAR20 is a good direct replacement for the incandescent R20 lamps that have been used in track lighting or small recessed cans over the past decades. Replacing these will give you more light while reducing energy costs. You can determine the kind of PAR 20 bulb by measuring the distance across the widest point of the bulb. The number after PAR wil represent the number of eighths of an inch the bulb diameter is. This means that PAR20 lamps are 2 1/2 inches across.Here"s a helpful tip about lighting a space or area with these lamps. Try to make the area you"re attempting to light a true highlight by making the light there three to five times as bright as the surrounding ambient light. This will cause attention to be drawn to the highlighted area. In many cases, people will gravitate toward these areas, so it"s good to have product or something interesting there for people to look at. The small size of these reflector lamps make it possible to put them in almost any small space or recessed lighting. Many people also use these halogen PAR20 bulbs for showcasing trophies, elevator, restaurants, clothing stores, jewelry, art work, sculptures, etc. and when shown under this light will appear more brilliant. In the case of retail lighting, the way you light something can make the difference in selling something or not.
