Lumens (light output)
This refers to the literal measure of the light-output of a particular light bulb, measured in the number of lumens.
Watts (Energy Used)
"Watts" is the term applied to the amount of energy required and used by a particular light bulb. It is an international system unit of power equal to one joule per second. Contrary to popular belief, the wattage of a bulb does not directly measure the brightness; the "lumens" of a light is what defines the actual light output.
Average Lifetime
This refers to an average lifetime rating based on large quantities in test groups. This testing takes into account usage of 3 hours per start for fluorescent lamps and 10 hours per start for HID lamps.
Volts
Voltage is a measure of electrical potential.
Bulb Type
|
The "Bulb Type" is typically a combination of the style of bulb as well as the width of the bulb. Usually, the first couple letters will indicate the type; "G" would indicate "Globe", "PAR" would indicate "Parabolic Reflector"... The numbers indicate the diameter of the light bulb in eighths of an inch; a "G40" would be a "Globe" style that is "5 inches" in diameter.
|
Base Type
|
The "Base" of a light bulb is the part that either screws or snaps into a receptacle. Base Type terminology may indicate common descriptive words like "Medium" or "Candelabra", or may even contain numeric codes that signify size and variety, like "E26" or "2GX13".
|
Filament Type
|
The filament is the style of fine wire that is heated electrically inside of an incandescent light bulb.
|
Color Temperature
Correlated Color Temperature (CCT) is a specification of the color appearance of a light bulb, relating its color to that of a reference source heated to a particular temperature, measured in degrees Kelvin (K). It generally measures the "warmth" or "coolness" of light source appearance.
CRI (Color Rendering Index)
CRI refers to the "Color Rendering Index" of a light bulb. CRI measures a light source and grades its ability to render the color of objects "correctly," as compared with a reference source with comparable color temperature. 100 is perfect rendering.
Length
This is sometimes referred to as MOL, or "Maximum Overall Length". It measures the absolute length of a light bulb, from the top of the bulb to the bottom of the base and is typically expressed in inches.
Width
Width refers to the complete diameter of the widest point of the light bulb.
Beam Angle
The beam angle refers to the width of the light beam coming from a reflector light bulb. The higher the number, the wider the beam spread.
# of Lamps
This refers to the number of Fluorescent or HID light bulbs that this particular ballast can light.
Bulb Type Used in Ballast
This refers to the style of light bulb that this particular ballast can light.

Local hardware stores didn't have this in stock, so I looked online and found eLightBulbs.com. I am very pleased, this is exactly what I needed for my kitchen light fixture. Since I have three of those, I ordered three and am keeping the other two in reserve. The service was quick, too.

Hurray. I looked everywhere for this bulb. I thought I would have to replace the fixture in my brand new house. Thanks! We will definitely be doing business again.

Received light bulbs well packaged and exactly what I needed. Could not get this type of fluorescent bulb in any of our local stores and was very delighted you carry the two ring type bulb.

Ordered near Christmas, arrived timely and in good condition. These lights are slightly brighter than the ones they replaced. And that's a good thing, the kitchen area has no windows and good lighting is important. I had some concerns at first when it did not appear they would fit snuggly in the retaining brackets but the brackets are adjustable. Would have preferred to have found these locally but apparently no one in a city of a quarter million will stock them, not sure why. Hope that means I won't be reordering any for at least 5 years, we'll see.

I would have purchased a "whiter" bulb, e.g., 6500K, if it had been available. I find the "TCP 58" bulbs to be fragile. I only bought these bulbs because the fit our kitchen light fixture.
