High Accuracy GPS / GNSS Streetlight Control Photocell
GPS-Controlled Photocells
GPS/GNSS photocell for precise dusk-to-dawn, part-night, and dimming control with energy savings.
Accuracy
The GPS/GNSS photocell integrates a colour-corrected silicon ambient light sensor with satellite-based synchronisation. This precise combination ensures highly accurate dusk-to-dawn switching, part-night operation, and dimming control, maintaining long-term timing accuracy without manual recalibration while delivering consistent energy savings and reliable performance.
Longevity
Engineered in the EU with a 15-year design life and backed by an 8-year warranty, the GPS/GNSS photocells are manufactured in-house to meet stringent ANSI and RoHS standards, ensuring long service life and trusted reliability in demanding outdoor environments
We pay more attention than any other photocell designer to the sky’s blue and red zones to ensure negligible sensitivity to infra-red and ultra-violet radiation.
