Ultraviolet Light
Understanding how fluorescent lights work begins with a basic understanding of how light is produced. The basic unit of light is the photon of light, which is released by an atom when its electrons are energized. As you know, electrons are negatively charged particles the nucleus of the atom orbit positive charge. The electrons have different energy levels and move when the power is won or lost by the atom. When the heat goes to the energy of an atom, the electron orbit quickly switch to another, and almost instantly return to their original positions. Jump back occurs, the additional power can be released as a photon of light, creating light.
We've all heard that fluorescent bulbs are more efficient than incandescent, but Why? Fluorescent bulbs use more efficient processes Production of light energy that we see. The main difference between incandescent and fluorescent lighting is being stimulate atoms. Incandescent bulbs excite atoms by the introduction of heat, resulting in an excess of unused thermal energy. Fluorescent bulbs also use a chemical reaction to excite the atoms of the same energy without overheating. These two types of bulbs to create ultraviolet light, which is not visible to humans. But fluorescent bulbs use only a substance that converts ultraviolet light visible light, resulting in less wasted energy.
A fluorescent lamp is usually a shell-tube-shaped glass with an electrode each end to connect to the electrical source. The lines of phosphor powder in the tube, and a small quantity of mercury and an inert gas, are contained within it. When power flows within and between the electrodes, the electrons travel the length of the tube, creating the energy that transforms mercury gas. As some of the atoms and electrons moving in contact with the mercury atoms, the electrons are excited, jumping a new orbit and emit photons of light and return to the initial orbit.
However, the light created by this reaction chemical is primarily in the ultraviolet, which is still not understood by the human eye. The phosphor powder coating the fluorescent lamp serves the purpose important to the transformation of light to visible light. When photons of light created from the chemical reaction that collide with a phosphor, the energy of electrons excites the phosphor, issuers and visible light. The games are the reason that we typically light from white fluorescent lamps.
The popularity of fluorescent lights growing because consumers are more environmentally conscious and seek solutions to save energy. Once it spread primarily in large office buildings and schools, the fluorescent bulb is now made with a base standard bulb so it is compatible with most common household fixtures lighting.

Can I use ultraviolet lamps for my plants?
I do not want to spend my money on a $ 150 bulb and heard that plain white cool ultraviolet light bulbs work I'd probably do two of them work. Thank you for your help
Regular cool white bulbs are not the same output UV bulb specifically designed for plant growth. Plants require a broad-spectrum bulb that can produce light in the UV-B. Cool white bulbs only live in the range of UV-A and usable emit very little plant needs. Cool white bulbs are good if they are more and more seedlings from seeds that will be phased in after sun. If they are fully developed plants (more than one set of true leaves), Cool white bulbs almost nothing for the plant. In any case, the plant becomes "leggy" as it extends into the lamp in a small trunk.
