Light exists in two forms: one in its natural form and the second one as a source of illumination. The natural medium of light comes from the sun and other very hot sources (now recognized as electromagnetic radiation that are governed with a wavelength of 400-750 nm), and within this particular wavelength a normal vision is possible. Light is also known as a source of inspiration, motivation as well as positive energy. Light travels at a speed of 299,792,458 m/s in vacuum.
As far as the daily use of light is concerned, one can use light through various mediums like: chandeliers, wall brackets, mirror lights, garden and outdoor lights, ceiling mounts, halogen lamps, lampshades, table lamps and pedestals, down lights, and no matter what.
Candles, on the other hand is a source of light and heat. It is made up of a solid block of fuel (in 95 percent of cases, wax is used to make candles) and an embedded wick. But this was not the case always. Earlier, the candles were manufactured from beef-fat rendering (I know you won't believe me, but it true) but now, they are made from wax.
Presently, candles are used for various reasons: they hold a true aesthetic value, at the same time they are responsible for setting a soft, warm, or romantic ambiance in the room, provide lighting during electric failures and more.
