GTI ColorMatcher D65 / 6500K
Artificical daylight lamps for the producing industry (color matching)
D65 D50 lamps
A properly designed colour viewing system / color matching system takes into account the performance and colour quality of the lamps. To ensure excellent colour rendering and close visual tolerance, all GTI colour viewing systems use our D50 Graphiclite 100 lamps and all our color matching systems use the D65 ColorMatcher lamps. GTI D50 Graphiclite 100 lamps and the D65 ColorMatcher lamps are manufactured with a unique blend of fluorescent phosphors that no other 5000/6500 Kelvin lamp in the industry can match. GTI lamps produce true full spectrum white light that reproduces colors with the highest accuracy and efficiency.
GTI´s Graphiclite 100 color viewing lamp produces an color rendering index (CRI) of approximately 95.
The D65 ColorMatcher lamps produces an an CRI of 98 rating of B/C based on CIE Standard 15.2 and Publication 51, one of the highest in the industry.
GTI viewing systems include a reflector, diffuser, cabin structure, lighting geometry and D50 Graphiclite 100 lamps / D65 ColorMatcher lamps.
A change in the formulation of this system may result in a slight color cast that affects the color evaluation, resulting in a viewing environment that is not ISO compliant. To maintain an ISO 3664:2009 (D50) respective ASTM D1729 (D65) compliant color viewing system, use only GTI D50 Graphiclite 100 / D65 ColorMatcher lamps and change lamps regularly.
D65 D50 Lamps – When to Relamp?
A lamp’s color output and intensity changes over time. To maintain consistent and accurate viewing conditions, viewing stations should be relamped after every 2,500 hours of use. GTI Graphiclite viewing stations should be relamped only with D50 Graphiclite 100 or D65 ColorMatcher lamps.
Relamp kits are available for all GTI viewing systems. On the plate on the back of your unit you will find the seriall number from your device or article number of the required lampset.
