Pioneering Technology
We pioneered the change to silicon eye response ambient light detection in photocells.
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.


Longterm Reliability
Our attention to long-term photocell accuracy and ambient light sensor selection guarantees peace of mind to our customers.
Rigorously Tested
Early failures are eliminated by a burn-in of each photocell for an intensive 48 hour period which simulates years of use. This eliminates infant photocell mortality after manufacturing and before our products are shipped.
