Specifications

General Specifications
	Watts	250WATTS A unit of electrical power. Lamps are rated in watts to indicate the rate at which they consume energy. This OSRAM 4052899431553 BBA Bulb is rated at 250 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 4052899431553 BBA Bulb is rated at 120 volts.
	Base Type	E26 (Medium Screw)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 4052899431553 BBA Bulb has a base type of E26 (Medium Screw).
	Bulb Type	A-21BULB TYPE The bulb type refers to the shape and class of the bulb. This OSRAM 4052899431553 BBA Bulb has a base type of A-21.
	Rated Average Life	4 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 4052899431553 BBA Bulb has an rated average life of 4 hours.
	Color Temperature	3400 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 4052899431553 BBA Bulb has a color temperature of 3400 K.
	Lumens	8700LUMENS 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 4052899431553 BBA Bulb emits 8700 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 4052899431553 BBA Bulb is rated at 100 CRI color rendering index.
	Bulb Finish	FrostedBULB FINISH The bulb coating of the bulb. Typical values include clear, frost, and colored. This OSRAM 4052899431553 BBA Bulb has a Frosted bulb finish.
