Lumen maintenance compares the amount of light produced from a light source or from a luminaire when it is brand new to the amount of light output at a specific time in the future. For instance, if a luminaire produced 1,000 lumens of light when it was brand new and now produces 700 lumens of light after 30,000 hours, then it would have lumen ...
The Honda VT1100 is a motorcycle engine used in the Honda Shadow 1100 motorcycle line since its debut in 1985 until production ended in 2007. In this 22-year run, there were minimal changes. It is a liquid cooled, 1,099 cubic centimetres (67.1 cu in), 45 degree V-twin. It has a bore and stroke of 87.5mm x 91.4mm with an 8:1 compression ratio.
The line changed little until the introduction of the 750 cc Honda Shadow Ace in 1997. From 2000 to 2007, the Honda Shadow Sabre replaced the VT1100 until the 1,100 cc class was discontinued in favor of the new VTX line, specifically the 1,300 cc offering known as the VTX1300. As of 2011, the Shadow brand has been limited to a single 750 cc ...
The Honda Shadow VT600C, also known as the Honda Shadow VLX, is a cruiser motorcycle made by Honda from 1988 through 2008. It has a 583 cc (35.6 cu in) liquid cooled V-twin engine, a four-five(from1999) -speed transmission, 35° rake, chain drive, and a single-shock softail -style rear suspension.
Brand new high-intensity discharge lamps make more visible light per unit of electric power consumed than fluorescent and incandescent lamps, since a greater proportion of their radiation is visible light in contrast to infrared. However, the lumen output of HID lighting can deteriorate by up to 70% over 10,000 burning hours.
The Honda Shadow Sabre (VT1100C2) refers to a cruiser-type motorcycle, that is part of the larger family of Honda Shadow. It was introduced in 2000 replacing the earlier Shadow A.C.E. It was retired after the year 2007. The Sabre name is being used again in the new 2010 Honda VT1300C custom line. [4]
Red is the most used color on Japanese emergency vehicles. Japanese police use light bars mounted on a raised (mechanical) platform to make them more visible over congested streets. Rotating lights are most commonly used. But some newer vehicles have LED light bars installed. Vehicles with any other light color than red are security or engineers.
The lumen (lm) is the SI unit for luminous flux, the total amount of light emitted by a source, weighted according to the sensitivity of the human eye to various colours of light. Lumens per watt is a common measure of the efficacy of a light source. The luminous flux is of less value for bicycle lighting due to the importance of directionality.
