Do I need special light fixtures?
No — The Energy Avenger™ treats your existing light fixtures.
What type of lighting can be bi-leveled reduced in voltage ?
Metal halide, high pressure sodium, mercury vapor and High Intensity Discharge (HID) lighting all respond very well to dimming.
Do any changes have to be made to my light fixtures?
No — your lighting stays as it is. Nothing is added to or taken away from the light fixtures.
Does the Energy Avenger™ reduces the life of the ballast and lights?
No — there is no measurable change in lamp life. Ballast life is not shortened. In fact, reducing the voltage to ballast reduces the amount of heat created in the coil; theory would suggest, then, that cooler running ballasts may even last longer and the lights will need to be replaced less often.
How does The Energy Avenger™ reduce the voltage required for lighting?
The system reduces voltage through use of a control transformer with “hard taps” to set the savings levels based on the IES guidelines.
Where is the Energy Avenger™ installed?
Typically, the Energy Avenger™ is installed next to the lighting panel.
Are my fixtures’ UL/CSA certifications affected?
No — The Energy Avenger™ system does not change any of the wiring or components of a light fixture. Some “retrofit” systems alter the lighting fixture components, and thus may affect UL/CSA certification.
How does the Energy Avenger™ impact lumen output?
The unit reduces lumens output, thus diminishing the harsh glare of the light. When the Energy Avenger™ goes through the steps down process it causes the color rendering index of the lamps to go through a kelvin shift. This shift causes the lamps to burn in the blue green spectrum which is a whiter day light that allows the eyes to see better.
How is this different from hi/low lighting?
The Energy Avenger™ system works very differently from hi/low lighting. It controls the voltage to all fixtures from the main lighting panel; no circuitry is installed in the ceiling or at the fixtures. In the unlikely event of a problem, our unit will default to full power through a phase failure relay system.
Why do I need more than the two levels a hi/low system would provide?
Many facilities find that the low level is too low for most activities, and that the high level doesn’t offer any savings. The Energy Avenger™ system allows for “hard taps” to be set at savings levels from 10% to 20% depending on the application. This greater flexibility creates a system that will actually be used — not just left at the high level. The result is substantially greater electrical savings.
Where have these systems been installed?
The Energy Avenger™ is installed from coast to coast in North America, tailoring solutions for a broad range of facilities including prisons, casinos, parking garages, car dealerships, post offices and public works facilities.
How much savings can the system produce?
The amount of savings depends on usage patterns. Typically, an area with a mix of occupied and unoccupied scheduling can save from 15% to 25%. The strategies outlined above can have a great effect on the total savings number.
Is the system electrically certified?
Yes — certification is available for all areas of North America.
What’s the difference between Power Conditioners and the Energy Avenger™?
A Power Conditioner is a device that specifically works to smooth the voltage of the electricity it supplies. This is done in a variety of ways such as filters, in-line resistors, wave chopping, wave rebuilding or shaping. The idea is to take existing wave forms and modify them to look like the 60 cycle sine wave. The Energy Avenger™ simply rides the existing wave and does not modify it in any way electronically. Through a series of switches and relays it simply lowers the voltage after the lights have reached its peak. Utilities use a similar system for variable high line transformer switching.
