Color Confidence Grafilite - Spare Bulb

View prints and colour swatches in natural light, indoors, day or night, with the Color Confidence GrafiLite. Color appearance becomes distorted under standard home and office lighting and surrounding colours will bias your colour perception. The GrafiLite allows you to assess colour differences accurately and clearly. The Color Confidence GrafiLite combines powerful, energy efficient simulated natural lighting with a space-saving lamp unit and mid-grey neutral viewing mat. Suitable for viewing proofs, prints or colour swatches, the GrafiLite is ideal for photographers, designers or anyone concerned with colour accuracy. Color Confidence Tip Although GrafiLite tubes are rated for up to 10,000 hours, illumination quality will deteriorate with use (from either continuous or intermittent usage). As with any professional viewing lamp, for optimum illumination quality, tubes should be replaced on an annual basis. We recommend adding a spare tube to your order (see options). Please do not attempt to use any other model of bulb in the GrafiLite as this may damage the unit or impair its operation. - See more at: http://shop.colourconfidence.com/product.php/1955/color-confidence-grafilite#sthash.VUI56jHa.dpuf
