Multi-Source overhead luminaires for visual color matching
For Accurate, Industry Standard Color viewing of Large Format Samples
GTI’s multi-source overhead luminaires enable accurate visual color matching and the detection of metamerism and fluorescence. Overhead luminaires provide a cost effective solution when configuring a viewing area for large samples or when a viewing booth is not practical . GTI overhead luminaire comes in two version (GLE-M luminaire and GLL-e luminaires)
GLE-M Luminaires
GLE-M luminaires utilizes an innovative optically clear, UV transmitting, prismatic diffusion lens for optimal light distribution. GLE-M series luminaires are available with three, four, or five light sources.
GLL-e Luminaires
The affordable GLL-e provides up to three light sources. GLL-e luminaires must be hard wired into a switched circuit (one for each light source) and do not have a built-in light control selector
GLE-M Key Features:
- Conforms to industry standards: ASTM D1729, SAE J361, BS-950, AS 1580, ISO 3668, AATCC Procedure #9, TAPPI T-515, TAPPI T-1212, ISO 3664:2009
- NIST traceable certificate of conformance
- Multiple light sources
- Optional wireless remote control
- Up to ten luminaires can be linked together
- A range of light sources available
- Range of sizes and models
