This extraordinary light is achieved by using rare phosphorswhich are blended in order to obtain the Accu-Tech color which produces a desirableKelvin temperature and high Color-Rendering-Index.
Best of all the Accu-Tech Fluorescents are economicallypriced at a cost which is generally half the price of our competitors equivalent product.
Color RenderingIndex (CRI) A key performance characteristic, color rendering, is theability of the light source to represent colors in objects. The relative measure of thisability is color rendering index or CRI which rates the light sources on a scale of 0 to100.
The higher the CRI, the more vibrant or close to natural thecolors of objects appear. Natural daylight has been assigned a CRI of 100 at a Kelvintemperature of between 5000-7500K. The Spectralite performs at 90 CRI which producesexcellent color rendition when color matching is critical.
CorrelatedColor Temperature(Kelvin), Color temperature or chromaticityrefers to the color appearance of the light that comes from a light source. Also referredto as Correlated Color Temperature (CTT), the apparent color of light source is measuredin Kelvin or "K".
Imagining a piece of iron (a horseshoe, for instance) in a firecan help you visualize color temperature in lamp types designated as "warm" or"cool". At first the iron becomes "red-hot". Red is the color of lightbe generated by the metal at a certain temperature. Continuing to heat the metal makes it"white-hot", and heating it further would cause it to become"blue-hot" (like flash bulbs or stars).
In describing color temperatures a low color temperaturecorresponds to a "warm" or a red yellow appearance like incandescent lamps at2700 Kelvin. "Cool" light comes from light sources like cool white fluorescentlamps operating at 4100 Kelvin. The higher the Kelvin temperature, the whiter and then thebluer the light. In the case of the Spectralite at 5900 Kelvin this produces a color onthe blue spectrum very close to natural daylight.

About Our Prices
We strive to provide you with the lowest prices possible on Walmart.com as well as in our stores. However, sometimes a price online does not match the price in a store.
