Powered from +500 V power supply, the KT66 prototype delivered 20 Watts at no more than 0.1% distortion. [25] A less costly +425V power supply enabled 15 Watt output power at no more than 0.1% distortion; this arrangement became standard for the Williamson amplifier and defined its physical layout.

Luminous efficacy can be normalized by the maximum possible luminous efficacy to a dimensionless quantity called luminous efficiency.The distinction between efficacy and efficiency is not always carefully maintained in published sources, so it is not uncommon to see "efficiencies" expressed in lumens per watt, or "efficacies" expressed as a percentage.
For reference, about 10,000 100-watt lightbulbs or 5,000 computer systems would be needed to draw 1 MW. Also, 1 MW is approximately 1360 horsepower . Modern high-power diesel-electric locomotives typically have a peak power of 3–5 MW, while a typical modern nuclear power plant produces on the order of 500–2000 MW peak output.
The maximum power measured is the nominal power of the module in Watts. Colloquially, this is also written as "W p"; this format is colloquial as it is outside the standard by adding suffixes to standardized units. The nominal power divided by the light power that falls on the module (area x 1000 W/m 2) is the efficiency.
Dynamic range (abbreviated DR, DNR, [1] or DYR [2]) is the ratio between the largest and smallest measurable values of a specific quantity. It is often used in the context of signals, like sound and light.
In June 2012, the Green500 list rated BlueGene/Q, Power BQC 16C as the most efficient supercomputer on the TOP500 in terms of FLOPS per watt, running at 2,100.88 MFLOPS/watt. [7] In November 2010, IBM machine, Blue Gene/Q achieves 1,684 MFLOPS/watt. [8] [9] On 9 June 2008, CNN reported that IBM's Roadrunner supercomputer achieves 376 MFLOPS/watt.
Schematic illustration of a supercapacitor [1] A diagram that shows a hierarchical classification of supercapacitors and capacitors of related types. A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than solid-state capacitors but with lower voltage limits.
The company was founded by the De'Longhi family in 1902 as a small industrial parts manufacturing workshop. [3] The company incorporated in 1950. [4] Historically a major producer of portable heaters and air conditioners, the company has expanded to include nearly every category of small domestic appliances in the food preparation and cooking, as well as household cleaning and ironing, segments.
