	Light Valve Theory of Operation (Site not responding. Last check: 2007-10-15)
		A low intensity image is scanned onto the rear side of the light valve; this causes the orientation of the polarization of the reflected image on the front side of the light valve to correspondingly rotate between 0 and 90 degrees.
		The image on the front of the light valve is formed by a corresponding raster scanned image on the rear side of the light valve.
		The arc lamp used in standard projectors tends to flicker, reduces its output with age, and is not a true point of light source.

	Single arc discharge headlamp with light switch for high/low beam operation - Patent 5023758
		The manner in which the arc light source 14 is mounted within the reflector 12 is not part of the invention, and it may be mounted in any suitable manner, such as the manner used for securing arc light source in presently used vehicle arc light source headlamps.
		Light from the arc light source 14 is reflected by the reflecting surface 16 and directed through the prismatic lens 18 to form the low beam pattern.
		Horizontally, the size of the beam projected by lens 26 is determined by the ratio of the width of the arc discharge between the electrodes of the arc light source 14 to the focal length of the lens 18.

	Operation Arc Light
		Operation Arc Light was the code name given to the use of B-52 strategic bombers in Southeast Asia.
		For its Arc Light role in Vietnam, the B-52D models were given the "Big Belly" mod to carry up to 108 Mk 82 (500-pound) bombs internally and on underwing pylons.
		Arc Light missions were flown over the Ho Chi Minh Trail in Laos and selectively in the southern part of North Vietnam.

		The light carried by the optical conductors is confined or condensed to the relatively small dimensions of the conductors themselves and is adaptable for use in various related space restrictive applications in automobiles and aircraft or other vehicles concerned with aerodynamic styling and efficiency.
		The light collected by the solid optical coupler devices 18, 20 travels through the coupler devices by a total internal reflection mode and is transmitted from their output ends 18A, 20A into the input ends 22A, 24A of the respective light distributing conductors 22, 24.
		The light distributing conductors 22, 24 conduct and guide the light to spaced preselected lighting positions, such as right and left positions on the front of an automobile, at which are located the light projecting arrangements 26, 28.

	Operation Arc Light - Wikipedia, the free encyclopedia
		Operation Arc Light was the 1965 deployment of B-52 heavy bombers to bases in Guam.
		By extension, arc light (or arclight) became the popular term for B-52 Stratofortress bomber missions flown during the Vietnam War in support of ground troops.
		The first use of these heavy bombers in Southeast Asia occurred on 18 June 1965.

	Brush's Arc Lamp
		During operation, the carbon electrodes are consumed at their tips, resulting in a widening of the gap between them.
		The upward movement of the upper carbon electrode establishes a gap and the arc of the lamp is "struck".
		As the lamp operates and the arc gap widens, the current flow through the electrodes is reduced.

	1939 - Evolution of Arc Broadside - SMPE
		The advantages of arc lighting became increasing pronounced as cinematographers drew away from the earliest flat lightings and began to experiment with the possibilities of creating effects of contour and separation of planes by contrasts in lighting.
		In others, a rigid studio policy dictated the lighting: in some such cases all the vapor lights might be used overhead, and all arcs on the floor; in others, vapor lights exclusively on the floor, and arcs overhead.
		Previously, because of the heat radiated from the arc, such diffusers had necessarily to be made of relatively narrow strips of glass, mounted in a frame that, for better ventilation, was simply hung rather loosely over the front of the lamp.

	Charles Francis Brush
		The arc light preceded Edison's incandescent light bulb in commercial use and was suited to applications where a bright light was needed, such as street lights and lighting in commercial and public buildings.
		Extended operation of the lamp requires the maintenance of a specific gap between the electrodes, which can be effected by moving the electrodes during operation with a regulating device.
		There were other arc lamps before Brush's that utilized electromagnets as part of a regulation system but it was the combination of the electromagnet with the ring clutch that made Brush's design superior in regulating the arc.

	Arc Light 1966
		The primary purpose of the Arc Light program was the destruction of major Viet Cong command and control and supply storage facilities through high altitude bombing.
		The requirement for Arc Light strikes quickly over stressed this capability requiring numerous major surges by Wing maintenance and air crews to meet the demand for B-52D sorties.
		In November 1966 26 Arc Light missions were flow in support of ground troops in Operation Attleboro, 50 miles Nowthwest of Saigon in Tay Ninh Province.

		The surrounding light is plenty to see the ground well at the position of the front tire and wide enough to navigate tight switchbacks with the light mounted to the bars.
		I have the light aimed so the bright spot hits the ground about 15 feet in front of me - road bikers probably would aim the light higher given their higher speeds and not needing to study the trail to pick a good line.
		The light is about half as powerful as a lowbeam car xenon lamp (which is also a metal halide lamp with xenon gas added to speed up the ignition and time to full output).

		The overall commitment of Arc Light units deploying was dependent on the monthly sortie rate flown against targets in Vietnam.
		Many air crew members who had participated in four Arc Light deployments were transferred to other SAC bases in the Summer of 1970, and replaced by crew members transitioning from other B-52 models to the B-52D.
		SAC B-52G aircraft, crews and staff were deployed TDY to Arc Light during this period and assigned to the 72nd Strategic Wing (Provisional), Anderson AFB.

	Windsor Electric Light
		There were about 27 lights exhibited, some of 16 and others of 32 candle power, displayed in lamps of various shapes and colours, the effect being exceedingly pretty, and the light soft and pleasant to the eye.
		Many were the complimentary remarks indulged in, the general opinion being that the light was excellent, and that the Company were to be commended for their efforts to give Windsor the electric lights, in the face of obstacles not easily overcome.
		While those who have seen the arc light in operation may have been disappointed at the lesser illuminating power of the lesser light there was really no reason to be so.

	Arc Lights and Super Gaggles: Examining the Air Battle for Khe Sanh
		Receiving warnings of incoming ARC LIGHT strikes (perhaps from Russian trawlers in the Pacific, which might intercept orders), his unit was able to systematically evade most of the bombing at Khe Sanh (Nalty 88).
		ARC LIGHT strikes, prior to Khe Sanh, were conducted farther than three kilometers from US forces.
		At Khe Sanh, ARC LIGHT bombing and the frivolous bombing runs planned by the "Red Watch" seem to emphasize destructiveness for its own sake, rather than as a means to win a battle.

	Airmen remember Linebacker II
		Operation Arc Light continued until Aug. 15, 1973, except for a brief pause between late 1970 and early 1972.
		In the end, Arc Light B-52s flying out of Andersen, U-Tapao, Thailand and Kadena Air Base, Japan, had flown nearly 130,000 missions, accumulated almost 900,000 flying hours, and dropped about 9 million bombs.
		Today, Andersen’s Arc Light Memorial Park stands as a tribute, not only to the 33 airmen from Linebacker II, but to the 75 men who lost their lives flying B-52 missions against communist forces in Vietnam between June 18, 1965, and Aug. 15, 1973.
