Best for critical colour decisions

These LED solutions achieve the best conformance to the CIE D50 and D65 illuminants available today, insuring accurate colour judgements. With JUST LED technologies using a mix of multiple coloured LEDs, this viewing solution has a more harmonious and complete light spectrum than even our ISO-spec fluorescent lamps.

Coupled with instant-on, infinite dimming, UV on / off, minimal heat output, and no mercury waste – at virtually the same price as the prior technology, the JUST LED luminaire is a cost-effective powerhouse.
