Frequently Asked Questions

What makes U-LINE ideal for glare-free classroom lighting?

U-LINE provides UGR<19 (glare-free) and indirect light distribution (10% uplight) that reduces eye strain and improves concentration — meeting EN12464-1 standards for educational and workplace lighting. Perfect for replacing outdated fluorescent indirect fixtures.

What is the difference between FU and FD optics?

FU (Flat Uplighting) directs 10% of light to the ceiling and 90% down, creating soft ambient illumination. FD (Flat Direct) is 100% downlight for focused task lighting — both available in 120° beam angle.

Can U-LINE be used to replace fluorescent indirect lighting?

Yes. U-LINE is designed as a direct retrofit for existing fluorescent indirect systems. It mounts on standard trunking rails and delivers 135–150 lm/W vs 60–80 lm/W of fluorescent, saving 60-80% energy.

Is U-LINE suitable for open plan offices with computer screens?

Absolutely. The UGR<19 rating and indirect light distribution minimize screen reflections and glare, making it an excellent low UGR linear light for offices.

Does U-LINE support emergency lighting?

Yes. Self-contained battery backup options are available, with automatic switch-over during power failure. DALI emergency versions also supported.
