A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.
A measure of "electrical pressure" between two points. The voltage specification of an incandescent lamp is the electrical "pressure" required to drive it at its designed point. The "voltage" of a ballast (e.g. 120 V) refers to the line voltage coming from the power source and is connected to the ballast.
Color Rendering Index is 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 accurately colors generally appear. CRI differences among lamps are not usually visible to the eye unless the difference is more than 3-5 points.
|Color Temperature (Kelvin)
Color Temperature (Kelvin)
An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).
A rating of the initial light output of a bulb, rated after 100 hrs of operation. Lumens are a measure of how much light falls on one square foot of area, one foot away from the light source.
|Average Rated Life (hr)
Average Rated Life (hr)
A measurement of the average length of time, between first use and the point when 50% of the lamps tested have stopped functioning, , using an operating cycle of 3 hours on, 20 minutes off.
Cubic feet per minute. a measurement of airflow volume, determined by how many cubic feet of air pass by a stationary point in one minute. Larger homes circulate more air (since there's more space for it to move around), so they will have a higher CFM.
Measure of noise, used for rating electrical appliances. Under 0.3 sones is extemely quiet. 1.0 sones is roughly equivalent to a refrigerator running. 3.0 sones would be a loud fan, roughly as loud as a face-to-face conversation.
|Duct Size (in)
Duct Size (in)
Size in inches for duct required for a bathroom extractor fan.
Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.
For fixtures and ballasts, width is the measurement of the total horizontal distance from left to right of the product in inches.
For ballasts and fixtures, height is the measurement of total vertical distance from the top of the product to the bottom expressed in inches.
The decorative finish of the item.
