What effect does The Ark have on different lighting types?
The Ark is able to generate high levels of savings on lighting loads, particularly the following types; • HID lighting • Standard fluorescent lighting • Incandescent lighting • Halogen lighting Lighting is typically a substantial and consistent user of electricity, so significant savings can be achieved by improving the efficiency of lighting loads. Optimising the voltage to the correct level will improve the efficiency of all types of lighting, including those with resistive or magnetic ballasts. If other energy efficient lighting devices have already been installed, The Ark can generally still create further savings, however the savings will be less than without the other energy efficient device. As well as creating energy savings, optimising the voltage provides significant improvements in the lifespan of lights. Incandescent lighting is particularly susceptible to high voltage levels and a 5% increase in voltage decreases the life of lamps by up to 47%. For fluorescent lamps, an in
