	Warm White LED Rope Light, LED Warm White Rope Light
		An LED (light emitting diode) is a solid state electronic component that emits light when electricity is passed through it.
		Linkable: several lengths of warm white LED rope light may be easily linked together using the threaded couplers that are supplied with each kit up to a total length of 240 feet.
		For example, one 15-foot length of rope light and one 30-foot length of rope light may be easily put together to form a 45-foot length of rope light, two 30-foot lengths may be combined to create a 60-foot length of rope light, and so on.

	The Clear White Light
		The light you have been seeing, as you have been creating these suggested images, one at a time, with your thoughts inspired by what you have been reading, is the inner light flooding through the external mind.
		When eftya, the clear white light, becomes more of a friend to his external mind than merely an occasional vision or experience and can be basked in during the four contemplative tyaasem periods of the day, then the nourishment to the entire nervoius system, as ambrosia, bursts forth from the crown chakra, kammakadeesareh kashumlinga.
		The natya is taught to withdraw his reactionary habit patterns in eftya, the clear white light, four times each day - during the kanef tyaasem - at six in the morning, twelve noon, six in the evening, and twelve midnight.

	White - Wikipedia, the free encyclopedia
		The impression of white light can be created by mixing (via a process called "additive mixing") appropriate intensities of the primary color spectrum: red, green and blue, but it must be noted that the illumination provided by this technique has significant differences from that produced by incandescence (see below).
		White is often associated with Conservatism (as opposed to Communism), particularly in the years following World War I, with civil wars fought between "Reds" and "Whites", for instance the Civil War in Russia and the Civil War in Finland.
		A white paper can be an authoritative report on a major issue, as by a team of experts; a government report outlining policy; or a short treatise whose purpose is to educate (contrast position paper) industry customers.

	Lights switch to organic LEDs (May 2002) - News - PhysicsWeb (Site not responding. Last check: 2007-10-26)
		When light from the LED enters the polymer layers, some of the blue photons are split – or ‘down converted’ – into two longer-wavelength photons by the phosphor particles.
		When the light emerges from the device, it consists of a wide range of wavelengths – that is, it is white light.
		Different white light spectra are distinguished by their ‘colour temperature’, which is the temperature at which a perfect fl body would emit the same spectrum.

	Howstuffworks "What is white noise?"
		White noise is a type of noise that is produced by combining sounds of all different frequencies together.
		The adjective "white" is used to describe this type of noise because of the way white light works.
		White light is light that is made up of all of the different colors (frequencies) of light combined together (a prism or a rainbow separates white light back into its component colors).

	Seeing The Light - White River Lighthouse
		In 1866, the pressure being applied by the Michiganders was felt, and Congress appropriated $67,000 for the construction of a new channel between White Lake and Lake Michigan, and $10,000 for the construction of a lighthouse at the harbor entry.
		William Robinson became the first keeper of the beacon light in 1872, and that same year the Lighthouse Board requested that the sum of $4,000 be appropriated for the construction of a keeper's dwelling on the shore near the pierhead light.
		Thus the character of the light was changed to a steady white light, varied by a red flash every forty seconds.

	White Light Shields
		It is not white say as in the white of a white sheet of typing paper, it is closer to the meaning of "white" like in the light radiated from a white light bulb.
		White light is the combination of ALL of the frequencies within the visible light spectrum of electromagnetic radiation.
		And while this light does begin to surround you (in a sense) in the astral once you attain a certain level of development, it is not a force, per se, that can be 'called down' or used or manipulated in any direct way.

	IPAC @ LLNL - Technology Profile: White Light Velocimeter
		To analyze the reflected light, these techniques use an interferometer that is extremely vibration-sensitive and difficult to align and requires heavy, expensive optical mounts and a sturdy platform.
		The white light velocimeter can be 100,000 times more vibration-tolerant than other techniques, so interferometer alignment is simplified and insensitive to drift.
		The white light velocimeter technology is available now for measuring velocities as low as 2 m/s and as high as 100,000 km/s.

	The Color of White
		When we compare different types of light sources such as incandescent lamps, tungsten-halogen lamps, various fluorescent lamps, and daylight during different times of the day, each source appears to transmit a different quality of "white" light, especially when these sources are seen side-by-side.
		The traditional response to the question of the optimum light source for viewing art has been to use the same type of light in which the object was either created or intended to be seen by the artist.
		A white reflective surface was illuminated at a fixed intensity as the color temperature was increased and decreased in small increments between 3000° K and 4700° K. Observers were asked to describe the light as warm, cool or intermediate.

	Single Beam White Light Reflection Hologram (Site not responding. Last check: 2007-10-26)
		This type of hologram is best viewed hand-held using a white light source as the reconstructing beam (such as sunlight or a flashlight).
		When viewing with white light, make sure the reconstruction angle is the same as the angle of the original reference beam (just move and/or tilt the hologram until you obtain the brightest image).
		The original laser light reference beam will work also for reconstruction, but the image will not be as bright as with white light reconstruction.

		White light pictures show how the Sun appears to the naked eye, when all the colors of the rainbow are collected by the camera.
		In a white light photo, the part of the Sun that we see is called the "photosphere".
		"chromosphere." We normally can't see the chromosphere in white light pictures, because it is so much fainter than the photosphere that the photosphere "washes it out." It's like trying to see a candle held in front of a much brighter spotlight.

	Photon Light Photon Micro Light
		Pressing and holding the button when the light is already off will turn it on at the lowest level and allow you to gradually increase the brightness to give you just the amount of light you need to accomplish your task without disturbing your night vision or disrupting those around you.
		The light output is slightly less than the white Photon, but is still very bright for its size (the batteries and the light itself actually take up about half the space of a Photon).
		Typically, light output measurements of a flashlight are taken by calculating the amount of light projected onto a spot about the size of an 8.5x11 sheet of paper.

	White Island Light History
		In 1838 White Island was nearly one of the first American lighthouses to have a Fresnel lens installed, but it was decided that the tower was too low for a satisfactory test of the lens.
		The Laightons left White Island in 1847 when Celia was twelve years old and eventually moved to the much larger island of Appledore, where the family operated a hotel for many years.
		The fog bell at White Island was replaced by a new bell and striking machinery in 1906.

	Color Addition
		We have already learned that white is not a color at all, but rather the presence of all the frequencies of visible light.
		White light can also be produced by combining only three distinct frequencies of light, provided that they are widely separated on the visible light spectrum.
		The light box illuminated a screen with the primary colors red (R), green (G) and blue (B); the lights were the shape of circles.

	EETimes.com - White LEDs to overtake the light bulb, keynoter says (Site not responding. Last check: 2007-10-26)
		Nakamura, the inventor of the blue, green and white LED and of the blue laser, had a trailblazing career as a researcher at Nichia Chemical Industries in Tokushima, Japan before recently accepted an appointment to the College of Engineering at UC Santa Barbara.
		White LEDs are twice as bright as incandescent bulbs, and will help preserve natural resources due to the use of non-toxic materials and to efficiency gains of InGaN-based LEDs, Kakamura said.
		A typical 60-watt light bulb puts out a lot of electromagnetic energy in the infrared part of the spectrum which can't be seen but is felt as heat.

	Exploring News & Features - Quantum dots that produce white light could be the light bulb’s successor (Site not responding. Last check: 2007-10-26)
		Until now quantum dots have been known primarily for their ability to produce a dozen different distinct colors of light simply by varying the size of the individual nanocrystals: a capability particularly suited to fluorescent labeling in biomedical applications.
		Although they are considerably more expensive than ordinary lights, they are capable of producing about twice as much light per watt as incandescent bulbs; they last up to 50,000 hours or 50 times as long as a 60-watt bulb; and, they are very tough and hard to break.
		As a result, the light produced by the quantum dots looks more nearly like the “full spectrum” reading lights now on the market which produce a light spectrum closer to that of sunlight than normal fluorescent tubes or light bulbs.

	Re: HOW DO THEY MAKE THE COLOR WHITE?
		A material such as a polished metal, which reflects almost all of the light, is not white because it doesn't transmit any light.
		A white pigment in the bulk such as a large crystal or a sheet of clear, colorless, glass or plastic reflects a small amount of the incident light and transmits the remainder.
		White is dependent on the lighting conditions, tungsten light, sunlight, fluorescent light, each gives its own character to white.
