TCP Springlamp brand 42 Watt, 120 Volt compact fluorescent lamp. Bright white color and high color rendering often used to light areas for detail-oriented applications.
• Outstanding energy efficiency - provides equivalent light to many 150 Watt incandescent lamps while using only 42 Watts of electricity
• Outstanding life - 10,000 hour rated life is five to ten times as long as most incandescent lamps
• Mogul Base (E39) - used in typically commercial/industrial fixtures.
NOT RECOMMENDED for use in enclosed fixtures or for use with control devices such as sensors or dimmers, may shorten lamp life
A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.
The wattage value of an incandescent or halogen lamp of similar brightness.
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.
The end (or ends) of the lamp that fits into the socket.
The description of the general appearance of a lamp/bulb consists of a letter(s) followed by a number. The letter indicates the shape of the bulb and the number relates to the diameter of the bulb in eighths of an inch. For example, a common household bulb is the A-19. The bulb is "A" shape and the diameter would be nineteen 8ths of an inch, or 2 3/8".
The color of the light produced by a bulb
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.
The surface finish of a bulb, which may affect the quality of the light emitted.
The technology implemented by the bulb, e.g. incandescent, halogen, LED
|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.
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.
Light bulbs: a measurement of a bulb's width taken at the widest point of the bulb. Fixtures: the measurement across the widest point of a circular fixture.
