NightFox™ photo controls are designed to include a solid state light sensor and relays that feature zero crossing technology for more precise control and long service life. As a leading manufacturer of photo controls, we truly understand the technology needed for today's lighting applications. We pioneered a comprehensive testing approach that took the best information from NEMA 410 and UL standards and combined them into a photo control testing methodology that ensures a maximized ROI. This testing gives us the confidence to back our products with 6, 8 and 12 years product warranties. Fixed mount photo controls provide an energy saving solution for light fixtures designed with knockouts. The photo control can be permanently affixed onto wall packs, outdoor light posts or other exterior lighting installations. Swivel type models allow the flexibility to adjust the photo eye based on the direction of the light.
