Fluorescent lamps are now widely used because they have a much lower power consumption than equally bright incandescent lamps. They are available in light colors sunlight, cool white and warm white.

Fluorescent lamps Design and function
Fluorescent lamps are one of the gas discharge lamp. It consists of a glass tube, which with mercury vapor and an inert gas such as argon or krypton filled. The inside of the glass tube coated with phosphor. This converts the light generated in the operation of the ultraviolet light in a longer wavelength, ie, into visible light.

The Incandescent lamps (light bulbs) is probably one of the most important discoveries ever! Without it we would have no electric lights. Thomas Alva Edison (1847-1931) intended to make light from an electric current. Edison experimented with various materials as filaments. If the thread is crossed by electric current, will to heat and begin to glow. Edison first tried it with the platinum. Then he burned some of the fibers and held it out so it gets more time to burn. He found that the filament will burn much longer if he brings them into a vacuum flask.

Batteries must be carefully handled. Here I have briefly summarized some important rules about handling batteries properly ..

Battery care tips

Never buy batteries for stock!
During long storage battery has a certain self-discharge, and this will increase at higher temperatures. Batteries are depleted (also alkali-manganese batteries!) May leaks, it is partly demonstrated by the fact that it has been stored in the contact of a white powder (potassium hydroxide). It is corrosive and corrodes all the metal parts that come into contact with it.
