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.

Bulb Shape

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".

Color Temperature (Kelvin)

An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).

Average Rated Life (hr)

Length (in)

Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.

Exactly what I was looking for


I have 3 pendant fixtures in my kitchen that use these bulbs. They are quick to install, just plug them into the fixture. They seem to last about 18 months with regular use. They give off excellent light. The two pendants over the pennisula are on a dimmer switch and that works just fine as well. Important for the life of the bulbs, don't handle a new bulb with your bare hands. I'm told they last longer if they don't get any skin oils on them. I just use a napkin or paper towel to hold the bulb when I replace one.

I have nothing to compare this product to, but the light quality is good....although I wish the bulbs lasted longer. They burn out more quickly than I would have expected.

Bulbrite 40W 120V T4 Frosted Halogen 9mm Bipin Bulb

Q & A
Does a halogen bulb give off the same warm glow as a regular incandescent bulb? And, does the wattage output (brightness or strength) look the same as well? I'm purchasing a chandelier that requires 6 - 40 watt bulbs and would like to know if it would be the same brightness as 240 watts of an incandescent light bulb or is it brighter and is the light white or does it have the same nice warm glow as a standard light bulb? Halogen is new to me so thanks for any help.

That is difficult to answer without additional information. First, a "regular" incandescent bulb would most likely have a E26 screw base. This halogen has an entirely different base. Please contact Customer Service at 888-455-2800 with additional information about your chandelier and we'll help you find the right light.
