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.

These could not be found in Home Depot or Lowes. Thank goodness for eLightBulbs. The lamps work well - brighter than original. Could be because the originals were old. Recommend to buy more than you need. Due to availability and good to have extra's on hand anyway.

Tube worked well for a short period in our kitchen fixture, then went dim. Alerted "eLightBulbs" of the problem and they IMMEDIATELY sent a new bulb.
GREAT service after the sale. Good pricing on a very hard to find tube. I would/will recommend "eLightBulbs" to anyone.

I looked to purchase this bulb at our local Home Depot where I purchased the light fixture from, but they no longer carry the fixture or the bulbs! Thank goodness I found eLightBulbs, now I know where to go first when replacing my light bulbs.

All exactly like I needed. I had a neighbor who sold light bulbs and he gave me boxes of stuff one of which was a fixture with a bulb of this type. Five years go by and the bulb goes; I search the product number on Google and this site had the exact replacement. To avoid needing to find it again, I bought 5. Should last me 25 years...
