  2. Ultra-high-performance lamp - Wikipedia

    en.wikipedia.org/wiki/Ultra-high-performance_lamp

    Ultra-high-performance lamp. An ultra-high-performance lamp, often known by the Philips trademark UHP, is a high-pressure mercury arc lamp. [1] These were originally known as ultra-high-pressure lamps, [2] [3] because the internal pressure can rise to as much as 200 atmospheres when the lamp reaches its operating temperature.

  3. Luminous efficacy - Wikipedia

    en.wikipedia.org/wiki/Luminous_efficacy

    The former sense is sometimes called luminous efficacy of radiation, [4] and the latter luminous efficacy of a light source [5] or overall luminous efficacy. [ 6 ] [ 7 ] Not all wavelengths of light are equally visible, or equally effective at stimulating human vision, due to the spectral sensitivity of the human eye ; radiation in the infrared ...

    Direct electric resistance tank water heaters are not included in the Energy Star program; however, the Energy Star program does include electric heat pump units with energy factors of 200% or higher. Tankless gas water heaters (as of 2015) must have an energy factor of 90% or higher for Energy Star qualification.

  5. Tankless water heating - Wikipedia

    en.wikipedia.org/wiki/Tankless_water_heating

    A hybrid water heater is a water heating system that integrates technology traits from both the tank-type water heaters and the tankless water heaters. [5] It maintains water pressure and consistent supply of hot water across multiple hot water applications, and like its tankless cousins, it is efficient and can supply a continuous flow of hot ...

    Up to 99.63 °C (the boiling point of water at 0.1 MPa), at this pressure water exists as a liquid. Above that, it exists as water vapor. Note that the boiling point of 100.0 °C is at a pressure of 0.101325 MPa (1 atm ), which is the average atmospheric pressure.

    en.wikipedia.org/wiki/Tilley_lamp

    In 1919, Tilley High-Pressure Gas Company started using kerosene as a fuel for lamps. [13] In the 1920s, Tilley company got a contract to supply lamps to railways, and made domestic lamps. [12] During World War II, Armed Forces purchased quantities of lamps, thus many sailors, soldiers and airmen used a Tilley Lamp. [12]

    Similar to fluorescent lights, HMIs present problems with color temperature when used for film or video lighting applications.Unlike incandescent-lighting units, which are blackbody radiators limited to a theoretical maximum of 3680 K (the melting point of tungsten), HMI lamps, like all gas discharge lighting, emit the emission spectral lines of its constituent elements, specifically chosen so ...

  9. Tanning lamp - Wikipedia

    en.wikipedia.org/wiki/Tanning_lamp

    You can also use a 160 W lamp with a 100 W ballast, although there are no advantages to this. Using a 100 W lamp with a 160 W ballast, however, can lead to quick failure as the cathode/anode of some 100 W lamps can not take the extra power. The lamps will operate at any frequency (50 Hz to 120,000 Hz or higher).
