Why Choose Up-Down Lighting for Private Offices?
Traditional single-direction lights create harsh shadows and annoying reflections on computer screens.

The Lumin UltLine X2 uses direct/indirect lighting logic. The downward light (direct) perfectly illuminates documents and desks, while the upward light (indirect) bounces off the ceiling, creating a soft ambient glow that balances room brightness and prevents eye fatigue.

Key Features & Innovations

  • Flexible Optical Distribution (LuminFocus & LuminFlood): Choose between LuminFocus (60° downward / 120° upward) for focused task lighting, or LuminFlood (120° upward / 120° downward) for perfectly uniform ambient illumination without"dark zones".

  • High Efficacy & Energy Saving: Delivers up to 130lm/W, significantly reducing electricity costs compared to standard 100lm/W fixtures. Features a high power factor (>0.98) and high-efficiency drivers.

  • LumiSun CRI 98 Technology: Simulates natural sunlight with less blue light hazard. It perfectly restores true colors and supports human circadian rhythms, ideal for premium office environments.

  • DIP Switch Selectable (Stock Saving): Adjust both color temperature (3000K/4000K/5000K) and wattage on-site via the top cover DIP switch. This"one light, multiple power"design drastically reduces your SKU inventory.

  • Easy Maintenance"X"Top Cover: The driver can be easily accessed and replaced by removing the top cover without uninstalling the entire fixture.
