Since 2007 Telelumen has been a world leader in programmable full spectrum LED lighting. Since 1975 GTI Graphic Technology, Inc. has been a leading manufacturer of viewing booths for the visual appraisal of critical color. During the InfoFlex trade show in Pittsburgh, PA from May 5^th to 6^th, 2025, the two companies will present a technology demonstration of a new programable full spectrum LED viewing solution.

The demonstration viewing booth will feature two Telelumen Dittosizer luminaires mounted on a GTI CMB-3052 color matching booth. The viewing area is 52” wide by 30” deep. The booth has the capability to output 10,000 lumens across 1,500K to 50,000K CCT spectrum, reproduce standard CIE illuminants such as D50 and D65, replicate any light source – LED, tungsten, fluorescent etc. and to be easily tuned to a specific custom target light spectrum profiles by using the built in touch screen. There are 12 industry spectrums pre-programmed and directly accessible through the touch screen. An optional physical separator can be inserted between the two luminaires for side-by-side viewing of similar objects under different light sources.

This new programable viewing system can eliminate the need for different lamp sets. With this one booth a user can easily view ISO 3664 and ASTM D1729 viewing conditions satisfying the need of the graphic arts and industrial color markets. At the same time end-use and retail lighting conditions can easily be replicated. This programmable and flexible color evaluation system will easily adjust to meet any lighting requirement enabling material testing to be more precise due to exact replication of all relevant lighting conditions.

The viewing booth is based on the Telelumen Dittosizer, a cutting-edge, fully programmable spectrum LED luminaire that uniquely integrates 24 independently controlled color channels, spanning from UVA to NIR. It delivers exceptional light output, exceeding 5,000 lumens, and is paired with advanced software capable of synthesizing any spectral power distribution. Telelumen’s software sets a new standard in flexibility, enabling users to precisely configure and resolve all 24 color channels to match any desired output spectrum. The Dittosizer can be adapted to fit on any GTI ColorMatcher viewing booth.
