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.

We broke an installed working one while removing it, but fortunately had ordered 3 so we now have 1 in reserve. It is for Sun Light desk lamp, no longer sold. The bulb is as bright as the original.

This is the second time I have purchased these from you. I have two floor lamps we have by the table for reading that use these bulbs. They are very economical and really help our eyes while reading the paper, computer, magazines, etc. instead of overhead light that used a lot more electricity and gave little help with reading. Thanks for being there. These are hard to find bulbs I was afraid I would have to get rid of my lamps until I found you on line.
