"Everything under control – with the LED Control System"

Our advanced LED control system gives you complete flexibility over your viewing light environment. Easily switch, dim, and manage standard illuminants D50 and D65, with the added ability to enable or disable UV content independently. A dedicated "UV-Only" mode operates separately and serves as a reliable UV-A light source. The built-in memory function automatically recalls your last settings upon power-up. You can also save and instantly recall preferred configurations—such as illuminant type, dimming levels and UV on/off settings—using the convenient "P1" and "P2" memory buttons.

For even greater versatility, our Remote Control v8 expands functionality by managing not only D50, D65, and UV-A, but also two customizable illuminants (ALT1 and ALT2), which can be individually configured to match CIE LED B1-B5 profiles.

With these intelligent control systems, you maintain full control over your viewing light conditions – ensuring accurate color assessments and reliable quality control every time.
