It was 1966, two years after the site move, when the first Zodion photocell was introduced. The pioneering SS2 was launched, helping to automatically control the switching of street lighting. This paved the way for the future of the company.



By the late 60s the company had become a key manufacturer of lighting controls. Producing electric lighting products suitable for use in streetlights and highways, Chadburn Controls (as it was then known) facilitated an emerging market that would continue to grow and prevails to this day.

The company’s status in lighting naturally generated a lot of interest from businesses in similar felds. It was in 1969 that the company went through another acquisition, this time with the Boston Group which owned Parking Meters of Aylesbury. This was transferred to the Luddendenfoot premises and the company’s name was changed again to Fisher Controls Ltd and Car Park Meters. 


Under the name Fisher Controls Ltd, still owned by Margaret Fisher, the company saw its most diverse product mix, which now also included the manufacture of parking meters. However, the main focus remained on their innovative range of photocells that helped offer effcient and automatic street lighting solutions, including a bespoke lighting system to ensure road safety on foggy highways.

In the same year as the acquisition, the company developed the very frst Photocell Thermal Units that use NEMA sockets; a technology that is still used to this day. This new product, along with the SS2, was widely used by local authorities throughout the UK. By the end of the decade more than 200,000 photo electric controls were in operation and time control switching was inevitably phased out.
