Lighting is very important in both residential and commercial spaces and the look of the space completely depends on how it has been lightened up.
One can buy lights online India but before that one has to know about the different varieties that are available these days and what are the purposes to use them.
These are the standard lights which are mainly available in a broad range of voltages and sizes and they are also widely used. These lights glow and produce some heat when the electricity is passed through the tungsten filament which is present inside the light. Here, the filament of the bulb is placed in the mixture of nitrogen gas or in a vacuum. But as these lights heat up very fast it can lead to the sudden breakout of the bulb. These lights mostly last for 700 to 1000 hours.
Compact Fluorescent Lights
They are a modern variety of lights which as per the name works as a fluorescent lamps. They contain mercury and they are difficult for disposal. They also use less power but produce the same amount of lights as that of an incandescent. They have 2 or 3 tubular loops and they have a life span of 10 thousand hours. They have 60 lumens per watt.
They mainly have tungsten filament and they are sealed with compact envelop and are also filled with inert gas. They are mainly smaller in size than that of the conventional lights and the halogen that is present there increases the lifetime and brightness of the lights.
Metal Halide Lights
They mainly contain a discharge tube or an arc tube within the bulb. The tube here can be made from ceramic or quarts and they also contain mercury. These metal halide lamps mainly produce great amount of lights and they are mainly used to light the traffics, halls and stages. They are also used in outdoor and for commercial purposes.
Light Emitting Diode
Popularly known as LED it emits light through the movement of electrons and semi conductor device. They lack filaments and they use less power and also have a long life span. They produce more lights than the others and also save a lot of energy. They also use a lot of colour filters.
They are the gas discharge tubes which provide a lot of visible lights. They have a good luminous efficiency and it is 45 to 100 lumens per watt. They also use much less power as compared to the incandescent lights but produce the same amount of lights.
They are the gas discharge lamps which mainly contain gas at low pressure. They are mainly assembled by mounting 2 electrodes within a very small glass envelope. When the voltage is applied to it, the light starts glowing and they allow a very small amount of current to travel from one electrode to another.
So, one can easily do online lights shopping India when the popular varieties are known to them.
