NP Focus-4 1CH Darklight
Light without glareThe NauticProfil® Focus-4 1CH Darklight luminaire insert features the same precision lenses and high-power LEDs as the standard version, but is additionally equipped with an aluminum cover for optimal glare control.
The full brightness is only perceptible on the illuminated surface, making the virtually glare-free luminaire a sophisticated and high-quality focal point on the ceiling.
The NP Focus-4 1CH Darklight is also optionally available with protective glass for the lenses.
The NauticProfil® Focus-4 1CH Darklight is available in lengths from 258 mm to a maximum of 2008 mm. For lengths from 1258 mm to 2008 mm, piercings are required on both ends.
Standard and custom lengths, including wattages, can be found in our datasheet.
