|
Watts |
20WATTS A unit of electrical power. Lamps are rated in watts to indicate the rate at which they consume energy. This TCP 4R4020TD50K Bulb is rated at 20 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 TCP 4R4020TD50K 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 TCP 4R4020TD50K Bulb has a base type of E26 (Medium Screw). |
|
|
Bulb Type |
R-40BULB TYPE The bulb type refers to the shape and class of the bulb. This TCP 4R4020TD50K Bulb has a base type of R-40. |

|
Rated Average Life |
12000 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 TCP 4R4020TD50K Bulb has an rated average life of 12000 hours. |

|
Color Temperature |
5000 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 TCP 4R4020TD50K Bulb has a color temperature of 5000 K. |
|
|
Lumens |
950LUMENS 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 TCP 4R4020TD50K Bulb emits 950 lumens. |
|
|
Color Rendering Index (CRI) |
82COLOR 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 TCP 4R4020TD50K Bulb is rated at 82 CRI color rendering index. |
