A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.
 
Energy Used
50 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".

Base

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

Double Contact Bayonet (BA15d)

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 (°)
10

Diameter (in)

Light bulbs: a measurement of a bulb's width taken at the widest point of the bulb. Fixtures: the measurement across the widest point of a circular fixture.
 
Diameter (in)
2.2

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)
2.2

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)
4,000

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.
 
Finish
Clear

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)
3000K

Q & A

Philips brand 50 Watt 56mm Aluminized Reflector halogen flood. 12 volts for low voltage systems.  Low voltage means a smaller fillament, for greater optical control. 

  • Halogen lights provide brighter, whiter light than incandescents, while maintaining  outstanding color rendering

  • 10º beam spread and a narrow beam of light.  Lamp can be farther away and still light the area effectively

  • Aluminized reflector eliminates backspill and bleedthrough

Glass lens - enclosed fixture not necessary
