The mercury vapor lamp is a high-pressure gas discharge lamp further. The glass bulb of mercury vapor lamps, high pressure usually has an elliptical shape. Inside the bulb is a quartz discharge tube, the mercury vapor. Because there are two main electrodes, is ignited by two ignition electrodes, which are located directly on 230V mains voltage (see figure).

Compact Fluorescent Lamps (CFL)
Compact Fluorescent Lamps (CFL) have very small dimensions and a curved glass tube. This makes it possible to provide them with a screw and screwed instead of normal bulbs in sockets. They are now also known as energy saving lamps.
Fluorescent lamps
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.
