|
Watts |
1000WATTS A unit of electrical power. Lamps are rated in watts to indicate the rate at which they consume energy. This OSRAM 14988 Bulb is rated at 1000 watts. |
|
|
Volts |
28VOLTS A measure of "electrical pressure" between two points. The higher the voltage, the more current will be pushed through a resistor connected across the points. The volt specification of an incandescent lamp is the electrical "pressure" required to drive it at its designed point. The "voltage" of a ballast (e.g. 277 V) refers to the line voltage it must be connected to. This OSRAM 14988 Bulb is rated at 28 volts. |
|
|
Base Type |
G53 (Screw Terminals)BASE TYPE The base is the end of the lamp that fits into the receptacle connected to the electrical supply. There are many types of bases used in lamps, screw bases being the most common for incandescent and HID lamps, while bipin bases are common for linear fluorescent lamps. This OSRAM 14988 Bulb has a base type of G53 (Screw Terminals). |
|
|
Bulb Type |
PAR-64BULB TYPE The bulb type refers to the shape and class of the bulb. This OSRAM 14988 Bulb has a base type of PAR-64. |
|
|
Rated Average Life |
50 hrsRATED AVERAGE LIFE This is the manufacturer provided rating for the average expected life of a lamp. For most lamp types, rated lamp life is the length of time of a statistically large sample between first use and the point when 50% of the lamps have failed. Note, this is not a manufacturer guarantee of life, but an estimate based on typical average testing. It is possible to define a "useful life" of a lamp based on practical considerations involving lumen depreciation and color shift. This OSRAM 14988 Bulb has an rated average life of 50 hours. |
|
|
Horizontal Beam Spread |
11°HORIZONTAL BEAM SPREAD The horizontal angular dimension of the elipse of light from reflectorized lamps encompassing the central part of the beam out to the angle where the intensity is 50% of maximum. The beam angle sometimes called "horizontal beam spread" is often part of the ordering code for the reflectorized lamps. This OSRAM 14988 Bulb has a beam spread of 11°. |
|
|
Vertical Beam Spread |
15°VERTICAL BEAM SPREAD The vertical angular dimension of the elipse of light from reflectorized lamps encompassing the central part of the beam out to the angle where the intensity is 50% of maximum. The beam angle sometimes called "vertical beam spread" is often part of the ordering code for the reflectorized lamps. This OSRAM 14988 Bulb has a beam spread of 15°. |
|
|
Candle Power |
540000CANDLE POWER (CANDELA) The measure of luminous intensity of a source in a given direction. The term has been retained from the early days of lighting when a standard candle of a fixed size and composition was defined as producing one candela in every direction. A plot of intensity versus direction is called a candela distribution curve and is often provided for reflectorized lamps and for luminaires with a lamp operating in them. This OSRAM 14988 Bulb emits 540000 candela of candle power. |
|
|
Color Rendering Index (CRI) |
100COLOR RENDERING INDEX (CRI) 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 true colors generally appear. CRI ratings of various lamps may be compared, but a numerical comparison is only valid if the lamps are close in color temperature. CRI differences among lamps are not usually significant (visible to the eye) unless the difference is more than 3-5 points. This OSRAM 14988 Bulb is rated at 100 CRI color rendering index. |
|
|
Filament |
CC-8FILAMENT Filaments are designated by a letter combination in which C is a coiled wire filament, and CC is a coiled wire that is itself wound into a larger coil. Numbers represent the type of filament-support arrangement. This OSRAM 14988 Bulb has a CC-8 filament. |
|
|
Operating Position |
UniversalOPERATING POSITION Mercury and High Pressure Sodium lamps may be operated in any burn position and will still maintain their rated performance specifications. Metal Halide and Low Pressure Sodium lamps, however, are optimized for performance in specific burn positions, or may be restricted to certain burn positions for safety reasons. This OSRAM 14988 Bulb has an operating position of Universal. |
|
|
Bulb Finish |
ClearBULB FINISH The bulb coating of the bulb. Typical values include clear, frost, and colored. This OSRAM 14988 Bulb has a Clear bulb finish. |
