A new addition to Lucy Zodion's extensive range of street lighting control products, the unique SS21 DALI photocell is factory programmable with up to eight stages of on, off and dim to offer energy savings along with a high level of control and flexibility. A long product lifespan is assured due to the use of high grade components, through hole plated PCB and a high impact UV stable polycarbonate casing. The SS21 DALI photocell has also been designed specifically to integrate seamlessly with modern lantern housings
