Product Description |
|
|
DULUX® D ECOLOGIC® Electronic Compact Fluorescent Lamps SYLVANIA DULUX D ECOLOGIC lamps are long-life, energy-saving alternatives for incandescent lamps. When paired with SYLVANIA ECOLOGIC linear fluorescent lamps, all the fluorescent lamps in an installation will be TCLP compliant. More compact than the DULUX S ECOLOGIC lamps, the 9 and 13 Watt DULUX D ECOLOGIC lamps are ideal for retrofitting existing fixtures and for use in dedicated, energy-saving fixtures where a small overall length is required. DULUX D ECOLOGIC 18 and 26 Watt lamps are used in dedicated fixture designs where high light output and maximum energy efficiency are required. They may also be used for retrofitting existing fixtures. Application Information Applications

| General Specifications | |||
|
Watts |
26WATTS A unit of electrical power. Lamps are rated in watts to indicate the rate at which they consume energy. This Sylvania 21115 Bulb is rated at 26 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 Sylvania 21115 Bulb is rated at 120 volts. |
|
|
Base Type |
G24d-3 (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 Sylvania 21115 Bulb has a base type of G24d-3 (2-Pin). |
|
|
Bulb Type |
T-4 Double TubeBULB TYPE The bulb type refers to the shape and class of the bulb. This Sylvania 21115 Bulb has a base type of T-4 Double Tube. |
|
|
Rated Average Life |
10000 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 Sylvania 21115 Bulb has an rated average life of 10000 hours. |
|
|
Color Temperature |
4100 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 Sylvania 21115 Bulb has a color temperature of 4100 K. |
|
|
Lumens |
1548LUMENS 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 Sylvania 21115 Bulb emits 1548 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 Sylvania 21115 Bulb is rated at 82 CRI color rendering index. |
|
|
Bulb Finish |
FrostedBULB FINISH The bulb coating of the bulb. Typical values include clear, frost, and colored. This Sylvania 21115 Bulb has a Frosted bulb finish. |
