| General Specifications | |||
|
Watts |
300WATTS A unit of electrical power. Lamps are rated in watts to indicate the rate at which they consume energy. This OSRAM 4008321746146 Bulb is rated at 300 watts. |
|
|
Volts |
120VOLTS 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 4008321746146 Bulb is rated at 120 volts. |
|
|
Base Type |
GX6.35 (2-Pin)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 4008321746146 Bulb has a base type of GX6.35 (2-Pin). |
|
|
Bulb Type |
T-6BULB TYPE The bulb type refers to the shape and class of the bulb. This OSRAM 4008321746146 Bulb has a base type of T-6. |
|
|
Rated Average Life |
75 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 4008321746146 Bulb has an rated average life of 75 hours. |
|
|
Color Temperature |
3200 KCOLOR TEMPERATURE A measure indicating the degree of "yellowness" or "blueness" of a white light source. Measured in kelvins, Color Temperature represents the temperature an incandescent object (like a filament) must reach to mimic the color of the light emitting from the lamp. Yellowish-white ("warm") sources, like incandescent lamps, have lower color temperatures in the 2700K-3000K range; white and bluish-white ("cool") sources, such as cool white (4100K) and natural daylight (6000K), have higher color temperatures. The higher the color temperature the whiter, or bluer, the light will be. The lower the color temperature the more yellow the light will be. This OSRAM 4008321746146 Bulb has a color temperature of 3200 K. |
|
|
Lumens |
8100LUMENS A measure of the luminous flux or quantity of light emitted by a source. For example, a dinner candle provides about 12 lumens. A 60-watt Soft White incandescent lamp provides about 840 lumens. This OSRAM 4008321746146 Bulb emits 8100 lumens. |
|
|
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 4008321746146 Bulb is rated at 100 CRI color rendering index. |
|
|
Operating Position |
s90OPERATING 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 4008321746146 Bulb has an operating position of s90. |
|
|
LIF |
CP/96LIGHTING INDUSTRY FEDERATION (LIF) CODE Codes that are assigned by the Lighting Federation of London U.K. They ensure electrical and mechanical interchangeability of similarly coded lamps. This is a european standard similar to ANSI codes in the US. LIF codes are divided into groups according to the primary application of the lamps. This OSRAM 4008321746146 Bulb has an LIF code of CP/96. |
|
|
Bulb Finish |
ClearBULB FINISH The bulb coating of the bulb. Typical values include clear, frost, and colored. This OSRAM 4008321746146 Bulb has a Clear bulb finish. |
