Textile, Printing and Publishing industries. A high CRI will be particularly useful where the true colour of light is important, e.g. So the higher the CRI, the more natural the colours will appear. Under a lamp with a low CRI, the colours will appear unnatural. The Colour Rendering Index (CRI) measures the ability of a light source to reproduce the true colour of an object, in comparison with a reference light source - for example, the sunlight.Р”Р‡or cool lamps, the reference light source is usually the natural daylight, whereas for warmer lamps the reference light source will often be an incandescent light. What does the term РІР‚Сљcolour renderingРІР‚Сњ mean? Used in specialist applications such as photography and architechural drawing. Possible applications in horticulture, aquariums. Also suitable for general lighting application in factories, parking lots, or warehouses.Р”В®xtremely white, simulate natural daylightР”Р„s it is very cold, generally not used for household applications unless specifically desired. Ideal for use in areas where clear illumination is paramount, such as kitchens and offices. Standard colour for many fluorescent and compact fluorescent tubes Often used in white rooms for a clean and modern feel. Recommended colour for average household useР”В¬olour of most halogen lamps, slightly whiter than incandescent Similar to incandescent lamp, appear tinged with yellow and gives a warm 'cosy' feel this is important especially in hospitals where patients are constantly indoors and have no other access to natural light.Р”В«elow is a list of the different colour temperatures, with some examples of possible applications this colour temperature replicates natural light and appears even cooler than cool white. In contrast, a cooler light will be used to enhance concentration, for example in offices and other working environments.Р”Р‡inally, hospitals and other medical practices will use daylight lighting. In general, the warmer light promotes relaxation and then will be suitable for general ambient lighting in housing (bedroom, dining room.) as well as in some public areas. What colour temperature should i choose for my lamp?Р”Р„ll colour temperatures can be used but for different applications.

So if you already know which colour temperature you have you can match it up with our manufacturer colour code in the table. ThatРІР‚в„ўs why we created our own table below as a reference point. This can get a little confusing if youРІР‚в„ўre not familiar with the manufacturersРІР‚в„ў codes. Here the 18 would represent the wattage of the tube and the 835 would refer to the colour temperature, 835 stands for 3500K which is white.

Often a tube could be referred to as L18/835. These numbers are colour codes that manufactures use to identify each of their products. In lighting, for white lamps, the colour temperatures vary roughly from 2700K, which is the very warm white, to 8000K which is sky white, almost blue. The higher the temperature, the bluer the colour. The lower the temperature, the redder the colour. He saw that the block was red at first, started to turn yellow as the temperature grew, and finished almost to a bright blue colour when the temperature was at its highest level. In the 1800s, a British physician, William Kelvin, heated a block of carbon. However, white can vary from a very warm white to a cool daylight, depending on the temperature of the lamp. I have cool white, neutral white and a few warm white lights but theyРІР‚в„ўre (almost) all A/D tints.A colour temperature is a measurement in degrees Kelvin (K) that indicates the hue of a light source.Р”Р„lthough there are special lighting colours (Blue, Yellow, Red.), most lamps are white. The B and Cs are on the green side until you get into warm white (IРІР‚в„ўm a green hater). All of the A and D tints are on the magenta side of the BBL line. I would rather have a good cool white than a bad, green tinted neutral white. I like cool white if itРІР‚в„ўs a good cool white, I love neutral white again if itРІР‚в„ўs a good neutral white.

To me, the second axis is more important than the color temperature axis. The second axis, which is really imaginary, runs top left to bottom right and represents how green or magenta the light is compared to a black body emission. The first axis, the BBL (the very faint dotted line running lower left to upper right) indicates the color temperature as represented by black body emissions. The 2 axes that are important are running diagonally on the chart. The ANSI chart has an X and Y axis, but itРІР‚в„ўs probably best to ignore them. I agree that color temperature is important, but since weРІР‚в„ўre not dealing with black body emissions, itРІР‚в„ўs important to consider how far a tint is from the Planckian locus ( BBL).
