Energy Used
A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.
Energy Used | 20 Watts |
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 | 12 |
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 | MR-16/L |
Base
The end (or ends) of the lamp that fits into the socket.
Base | GU5.3 |
Beam Spread
The width of a light beam, expressed in degrees. The beam spread is often part of the ordering code for reflector lamps. For example, a 50PAR30/HIR/NFL25 is a 50-watt PAR30 narrow flood lamp with a beam spread of 25 degrees.
Beam Spread | 8° |
Class and Filament
A designation used to describe the shape or structure of the filament in an incandescent or halogen light bulb. Most commonly used for specialty products like rough service and antique replica lamps.
Class and Filament | C,C-8 |
Diameter (in)
A measurement of a bulb's width taken at the widest point of the bulb.
Diameter (in) | 2.000 |
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) | 2.000 |
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.
Average Rated Life (hr) | 5,000 |
Light Output
A unit measurement of the rate at which a lamp produces light, most often provided in lumens or candlepower. Ratings of initial light output provided by manufacturers express the total light output after 100 hours of operation.
Light Output | 6,500 MBCP |
Finish
A reference to 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).
Finish | Warm White |
CRI
Color Rendering Index is an international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale) the richer and more accurately colors generally appear. CRI differences among lamps are not usually visible to the eye unless the difference is more than 3-5 points.
CRI | 100 |
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) | 3150K |
GE
A General Electric brand-specific product number for an equivalent item and is provided for the purpose of cross-referencing.
