1. What is a base size?
- Candelabra type screw base - (E12) is also known as a Candelabra Edison Screw and the E-12 designation denotes that the base is 12mm in diameter.
- Candelabra type screw base - (E14) European Threaded Candelabra Screw base - the E14 denotes that the base is 14mm in diameter
- Intermediate screw base - (E17) Intermediate base - (Type C base) used in many different appliances
- Medium screw base - (E26/24) - (Type M Base) recognized as a standard size base - 26/24 denotes the base is 26/24 mm in diameter
- Medium screw base - (E27/25) - European Medium Base - 27/25 denotes the base is 27/25 mm in diameter
- Candelabra Double Contact Bayonet Base - (BA15D) - Candelabra Base with two contact pads on the bottom of the base
- Candelabra Single Contact Bayonet Base - (BA15S) - Candelabra Base with one contact pad on the bottom of the base
- Wedge Base - A wedge base is fusion sealed about the filament support legs and the exhaust tube. The base has a multitude of "ribs" adapted to be frictionally received in a wedge base bulb socket. The ends of the support legs are formed along the ribs for making electrical contact with the socket terminals.
- Wedge Base w/Extended Leads - Is the same as above with longer support legs
2. What shape/sizes do bulbs come in?
The letter denotes the glass shape and the number that follows denotes the glass size which is the maximum diameter of the bulb displayed in eights of an inch.
3. What are the different bulb finishes?
- 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.
- 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.
- Clear - Clear glass finish.
- 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.
4. How long does a bulb last?
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.
5. What is a "Long life" bulb?
Long life light bulbs differ from standard light bulbs in 3 ways:
- Use of a heavier 5 point filament design.
- Use of a variety of gases (krypton, xenon, argon) to stabilize the breakdown of the filament.
- Use of a heat deflecting ring at the base of the bulb.
6. What are special characteristics of a range lamp?
A range lamp is made to withstand high intensity temperatures for long periods of time. Their solder and cement must not break down during extreme heat. Our bulbs withstand 586° F of continuous temperature.
7. What are Watts?
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.
8. What are Volts?
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.
