Energy Savings for HID Lighting through a multi-level control system. With energy costs on the rise, there is a need for a better control of energy usage. Efficient, well-designed lighting systems offer a tremendous opportunity to reduce energy consumption while maintaining productivity. The KiloWatch system from Lithonia Lighting combines the high efficiencies and energy savings of High Intensity Discharge lighting with proven control technology, allowing you to have light when you need it...and save energy when you don't. KiloWatch systems can reduce lighting power cost by up to 40%

Many environments are occupied only a portion of any given day. During the balance of the time, only minimum lighting levels are required for safety. In a typical warehouse environment (applications similar to picture on the left), loading docks and shipping/receiving have the highest activity, but are contained in a small percentage of the total square footage. The balance of the warehouse usually contains aisles with rack storage locations that may require occupancy only a couple of times a day. When there is no occupancy in the aisles, the lighting level should not be a concern; therefore, use of a sensor system with a 50% power reduction will maximize energy savings. When a worker enters the space, KiloWatch automatically switches the light level to full brightness, this level of illumination is only required possibly 20% of the time. Then when worker leaves the space, KiloWatch switches the light level to low, possibly 80% of the time. The energy-saving KiloWatch system allows you to maintain a minimum lighting level at reduced power consumption when areas are not in use, then gives almost instantaneous full lighting when required.

The expectations of a high school gymnasium (applications similar to picture on the right) are no longer just basketball, they are now multi-purpose facilities that include gymnastics, wrestling and even baseball practice during the off season. With the wide array of activities and more hours of operation, a multi-purpose system is excellent for this changing environment. Physical education classes or recreational basketball requires half the illumination that the varsity basketball team would need to practice or for game play. A traditional lighting system would be designed to the higher foot-candle requirement. This level of illumination is only required possibly 30% of the time. The use of the KiloWatch system allows the luminaire to be switched to a 50% lumen reduction and still maintain the proper lighting for other activities.

KiloWatch is the solution to providing proper lighting for the work environment while conserving energy and saving money.

The simple design of KiloWatch permits easy installation and many years of energy-efficient operation. A manually switched system places the control of light levels at your fingertips, while the second system utilizes sensing devices. Motion detectors, photocells and other devices are incorporated to control the light output automatically. Sensing devices allow for maximum energy savings.

Pulse Start systems are compatible with KiloWatch, it is recommended taking advantage of Pulse Start systems where applicable for greatest energy savings. Please see Pulse Start Calculator for further information. Pulse Start systems are designated in chart below Wattage/Source with a SCWA ballast.

Lithonia's KiloWatch dual-level system is designed around ease of installation, simplistic operation, and proven technology.

Regardless of control method used, manual switch or sensor, the luminaire electrical components are identical. Lithonia uses standard ballast, capacitors, and when required, ignitors. The control is accomplished by adding a second capacitor and switching it in or out of the circuit with a 120V or 277V AC control relay, installed in the luminaire. The control relay is part of the luminaire that is directly connected to the wall switch in a manual system or the control sensor system by a separate 120V or 277V AC control circuit.

In our continual efforts for energy savings product we have added an integral sensor system (specification sheet) designed to control a single HID fixture. The control is accomplished by adding a second capacitor and switching it in or out of the circuit with a solid state control relay, installed in the luminaire. There is a armored cable connected to the side of a pendent splice box on fixture that connects the relay to the sensor, which mounts to the reflector. No extra system wiring is needed for installation purposes. The integral sensor system will maximize the possible energy savings in a sensor application.

The KiloWatch calculator allows you to compare full power output versus a 50% power output for various lamps (a 50% lumen output version is also available). To fully appreciate the energy savings potential of the KiloWatch system, one must understand the energy consumption of a standard lighting system. Subtracting the energy consumption of the KiloWatch system from a standard system reveals the total energy savings using the KiloWatch multi-level lighting system. All inputted watts are based on the most recent published information from ballast manufacture. Up to date details specific to input wattage should be verified with ballast manufacture.

The KiloWatch Calculator Excel (Version '97) allows users to download program onto computer, moreover calculates simple payback on estimated initial capital cost.

All testing has been completed under stabilized laboratory conditions. Various operating conditions and ballast/capacitor/lamp variations can cause differences between laboratory data and actual field measurements. Specifications on sheets are based on the most current data and are subject to change without notice. We do not recommend dual wattage lamps use for KiloWatch systems
