Energy Conservation Unit

The Shepherd® energy conservation unit is designed on the basis of technology that even though the rated voltage is specified by lamp manufactures to start fluorescent and gas discharge lamps, the resulted arc can be sustained and stabilised at lower voltage also. Fluorescent and HID lightings systems, HID lighting includes metal halide, high pressure sodium and mercury vapour lamps do not have linear Lumens-Watts curve, i.e., the increased power will not give proportional increase in light output (lumens). Conversely, slight reduction of the power supplied does not reduce the light output proportionally. Such voltage reduction is achieved by introducing virtually loss less impedance in the path to reduce power consumption at optimum level. Efficiently and properly designed with saving oriented applied technology, the energy conservation unit is customising entire systems more efficiently and in a user-friendly manner. This results in an increase in lighting efficiency (lm/w) of >20% enabling a sign
