A volt is the unit of electric potential difference, or the size of the force that sends the electrons through a circuit. Voltages vary from application to application depending what the requirements are. Different voltages (230V) are required for European product that is produced. The United States typically runs on 120V.

A. Blue Powder - Blue Powder bulbs are bulbs that have powder electrostatically adhered to the glass. They give off much of the same pure light as does the Neodymium. But the powder diffuses the light and gives off a softer glow.
B. Internal Frost - The bulb either has a white powder electrostatically adhered to the glass or the glass is etched with acid to obtain the “frosted” look. The frost diffuses the light giving the bulb a softer glow.
C. Clear - Clear glass finish.
D. Neodymium Blue (Blue Glass) -When these bulbs are lit, the neodymium provides a pure, clean light by filtering out much of the dulling yellow cast common from ordinary light bulbs.
Light bulb manufacturers adhere to a standard industry rating for light bulb life called "rated life." The rated life is a measure of the median time in hours that it takes for a light bulb to burn out. This is the point in laboratory testing at which half the test bulbs have burned out and half the test bulbs are still burning.
A 60-watt incandescent bulb may have a rated life of 1,000 hours. However, not all bulbs of this type will last exactly that long. That rated life is the median — the point in lab testing when 50% of the test samples have burned out and 50% are still burning.
Electrical power is measured in watts. In an electrical system power (P) is equal to the voltage multiplied by the current. Watts = Volts x Amps Most appliances use bulbs that are low in wattage. Some of the more common wattages found in appliance light bulbs are 15, 25, 40 & 60 watts.
