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
-
25º beam spread and a narrower 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

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

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

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".
| ALR |
Bulb Color
The color of the light produced by a bulb
| Soft White |
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).
| 3000 |
Brightness (Lumens)
A rating of the initial 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.
| 820 |
Candle Power
A measure of how much light the bulb produces, measured at the bulb, based on the amount originally emitted by a single candle.
| 2300 |
Bulb Finish
The surface finish of a bulb, which may affect the quality of the light emitted.
| Clear |
Bulb Technology
The technology implemented by the bulb, e.g. incandescent, halogen, LED
| Halogen |
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.
| 4000 |
Beam Angle (°)
The width of a light beam, expressed in degrees. The beam angle 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 angle of 25 degrees.
| 25 |
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.
| 2.25 |
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.
| 2.2 |
Dimmable
Indicates whether a product can be dimmed in conjunction with a suitable dimmer control.
| Yes |
