 – Items listed with this icon are Energy Star qualified. |
| |
| ** – This notes that the listed M.O.L. (Maximum Overall Length) of the lamp is in inches. |
| |
| ANSI CODE – 3-letter code assigned by the American National Standards Institute. This provides a system of assuring mechanical and electrical interchangeability among similarly coded lamps from various manufacturers. |
| |
| AVERAGE RATED LIFE – 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 burnt out. |
| |
| BASE – The base is the end of the lamp that fits into the socket. There are many types of bases used in lamps: screw bases are the most common for incandescent and HID lamps, while bi-pin bases are common for linear fluorescent lamps. |
| |
| BEAM SPREAD – For reflector type lamps. The total angle of the directed beam (in degrees horizontal or vertical) to where the intensity of the beam falls to 50% or 10% of the maximum candlepower value as indicated. |
| |
| CENTER BEAM CANDLE POWER (C.B.C.P.) – Refers to the luminous intensity at the center of the beam of a blown or pressed reflector lamp (such as a PAR lamp). Measured in candelas. |
| |
| COLOR RENDERING INDEX (CRI) – A measured value that indicates the color-rendering quality of illumination provided by a light source. The higher the index number, the better the quality of illumination and the richer that colors will generally appear. While one lamp may have the same apparent color in C.C.T. as another, its ability to render colors properly may be more or less than another light source. |
| |
| CORRELATED COLOR TEMPERATURE (C.C.T.) – Describes the apparent color, or chromaticity, of a light source (measured in Kelvins). A fluorescent light source of 3000K, for example, has a warm chromaticity. 5000K lamps have a higher blue content and are considered to be cooler in color. |
| |
| DESCRIPTION – The lamp's identifying description. It typically includes the lamp shape and size. |
| |
| FINISH – The color or finish on the glass shell or lens of the lamp. Typically clear, white, or frost. |
HALOGEN LAMP BEAM ANGLE
Spot = 10 degrees
Narrow Flood = 20 degrees
Flood = 28 degrees
Wide Flood = 50 degrees
|
| LIGHT CENTER LENGTH (L.C.L.) – The distance between the center of the filament or arc tube and a reference plane - usually the bottom of the lamp base. |
| |
| LUMENS – 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. |
| |
| MATERIALS SAFETY DATA SHEET (M.S.D.S.) – Required safety information about each lamp. |
| |
| MAXIMUM OVERALL LENGTH (M.O.L.) – The end-to-end measurement of a lamp, expressed in inches or millimeters. |
| |
| ORDERING CODE – It is important to use this code when ordering to ensure that you receive the exact product you require. |
| |
| QTY/CASE – Number of product units packed in a master case. |
| |
| VOLTS – 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. |
| |
| WATTS – A unit of electrical power. Lamps are rated in watts to indicate the rate at which they consume energy. |
