Volts

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.
 
Volts
120

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".
 
Bulb Shape
T-3/4

Base

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

Diameter (in)
0.44

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.
 
Length (in)
4.72

Average Rated Life (hr)

A measurement of the average length of time, between first use and the point when 50% of the lamps tested have stopped functioning, , using an operating cycle of 3 hours on, 20 minutes off.
 
Average Rated Life (hr)
400

Brightness (Lumens)

A rating of the inital light output of a bulb, rated after 100 hrs of operation. Lumens are a measure of how much light falls on one square foot of area, one foot away from the light source.
 
Brightness (Lumens)
12500

Finish

Light bulbs: the coating applied to the bulb causing light to be emitted in certain colors or color temperatures (see Color Temperature). Popular finishes include clear, frosted, colors (amber, blue, green, red, etc.) as well as color temperature designations ranging from warm white (2700K) to natural daylight (6500K). Fixtures: the decorative finish of the item.

Frost

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).
 
Color Temperature (Kelvin)
3200K

Q & A

Eiko brand double-ended linear halogen capsule.  500 Watts and 120 volts for bright, high intensity light.  

  • Frosted for less glare

  • Halogen lamps provide brighter, whiter light than incandescent bulbs, while maintaining outstanding color rendering

DOUBLE CHECK your lamp length.  This lamp comes in two lengths.  Length for this version is 4.72"

NOTE - this is not a general purpose lamp.  Light output is greater and color is brighter than equivalent halogen lamps, but rated life is only 400 hours.  Generally used in photgraphic or scientific applications.
