A measure of "electrical pressure" between two points. The voltage specification of an incandescent lamp is the electrical "pressure" required to drive it at its designed point. The "voltage" of a ballast (e.g. 120 V) refers to the line voltage coming from the power source and is connected to the ballast.


The end (or ends) of the lamp that fits into the socket.

The description of the general appearance of a lamp/bulb consists of a letter(s) followed by a number. The letter indicates the shape of the bulb and the number relates to the diameter of the bulb in eighths of an inch. For example, a common household bulb is the A-19. The bulb is "A" shape and the diameter would be nineteen 8ths of an inch, or 2 3/8".

Top Quality


These bulbs are in my unheated garage and light up the utility area near my hot water tank and water sprinkling system. They work well for their intended use and have been very cost effective compared to similar bulbs I was purchasing from large construction stores in Las Vegas.

Finally found these!


I had been looking for these bulbs for quite some time. They apparently aren't common enough to be found in a [...] or [...]. The halogen bulbs are confusing, as there are a lot of different shapes and sizes and base sizes. I think has every option. I had bought several incorrect bulbs for $5 to $6, so I'm glad I finally found the correct ones.

Q & A
How do I check the distance between pins on 20 watt bulbs?? There are no markings on the bulbs on my accent light fixture.


The distance between the pins is measured in millimeters. This particular bulb has a GY8 base so the pins would be 8mm apart. There are different base types for these types of halogens. The base types depend on the wattage and voltage of the bulb. If the current bulbs have a different measurement than 8mm, we would recommend checking the fixture to see if they list the wattage or type of bulb needed.
