GTI’s overhead luminaires are the key component when configuring an ASTM D1729-2009-compliant, large sample viewing area. GTI’s unique design allows you to operate up to 10 overhead luminaires with a wireless remote control. The light source control panel provides "instant on" source selection plus easy-to-use automatic light source sequencing. GTI’s ColorGuard II program indicates hours used and hours until relamping for all sources. Up to five light sources can be included. View GTI’s Multisource Luminaire Video
