Lamp life

Lamp life

Varies from source to source.

rated lamp life

% rated lamp life vs. % of initial lamps which survive A life expectancy curve for incandescent lamps
1. The average life of a lamp of a given type, as determined from a large sample operated under laboratory conditions; the average life of a group of lamps which are operated under variable conditions may not equal the rated lamp life.
2. For lamp types whose luminous output drops to a very low value before the lamps cease to operate: the time when the output of a large sample of lamps under controlled laboratory conditions reaches a specified fraction of the initial output.

Eight New Models Offer Brightness, Connectivity and Up to 10,000 Hours of Lamp Life in Economy Mode
The Max-Power LED Swivel Coupler produces bright white light similar to daylight and, with average LED lamp life being 10 times that of xenon bulb life, is expected to save time and money through fewer lamp replacements.
The latest generation of BenQ projectors are made for small- to medium-sized spaces and have new features, including an increased brightness of 2,800 ANSI lumens, a contrast ratio of 13,000:1, a longer lamp life of up to 6,500 hours, and SVGA (MS517), XGA (MX518), and WXGA (MW519) resolutions.
This is combined with superior lamp life of more than eight years, which yields additional savings opportunities.
The lamps can be operated at higher temperatures while the back of the quartz tube remains cool, thereby extending lamp life.
Advantages for plant researchers over existing T12 and T5 fluorescent systems include energy savings up to 70 and 50 percent, respectively, greater average PPF tailored to the photosynthetic action spectrum, improved horizontal and vertical light uniformity, a dimmable ballast to adjust PPF output to 50 percent of maximum without uniformity or spectral degradation, and a 30,000-hour rated lamp life.
There are two operating settings, normal for maximum performance, and an "eco-mode" for low noise levels and extended lamp life.
Additional LED light fixture benefits include reduced maintenance costs from increased lamp life and no need for ballasts which may occasionally fail and require replacing.
These factors allow for the RadReflect (ceramic reflective coated quartz lamps) to be operated at higher application temperatures while keeping the back of the high quality quartz tube cool and thereby extending lamp life.
With 4,000 lumens and a 2,000:1 contrast ratio, the PJL9371 offers energy-saving features such as an eco mode, a hybrid fitter design, and 5,000-hour lamp life.
This product is unrivaled with its unique design and efficacy, providing lamp life of up to 60,000 hours," said Access Fixtures CEO, Steven Rothschild.
It also includes eco-conscious features like ECO Mode, which increases lamp life up to 10,000 hours, while lowering power consumption to help schools decrease their overall total cost of ownership.
