Consider This
While there have been
many power reduction devices available for fluorescent light over the years,
they have almost universally worked on the principle of restricting the amount
of power the ballast can draw by reducing the peak voltage. In effect, these
power restrictors simply "dim" ballasts that were not originally designed to be
dimmable. The percentage of watts saved is roughly equal to the percentage of
lumens lost.
The EnerLume-EM® works on a completely different principle. It does not limit the amount of power the ballast draws, it restricts when it may draw power. AC power is delivered in a sine wave. A single wave happens very fast - 60 times per second. Ballasts need power to
operate the fluorescent tubes. By restricting when on the sine wave cycle the ballast may draw power, the
EnerLume-EM® allows the ballast to get the power it needs when it is efficient to do so. This results in lower
power consumption.
This way, the ballast still provides very nearly all the power the tubes need to maintain full brightness. This is why, at a very significant electrical savings of 15%, there is no detectable loss of light. This is simply because the tubes still get the power they need. The
EnerLume-EM® guides the ballast to create the needed power for the fluorescent tubes with less power pulled from the Utility. This leads to longer ballast life
and reduced cooling costs.
With the EnerLume-EM®, the facility manager can further increase the savings beyond the 15%. Beyond this, depending on the ballast used, there will be a dimming effect as the time restriction becomes great enough to interfere with the ballast's ability to get enough power to provide the tubes
with what they want. That said, it is still not in direct proportion. The additional power savings exceed the lumen loss. Users report savings of up to 30% in power consumption.

What is the EnerLume|EM®
The EnerLume|EM® is an energy saving device for use with new or existing fluorescent lighting systems. By conditioning the incoming power wave, it reduces electrical consumption with negligible lumen loss at savings up to 15%. Greater savings are possible with some lumen loss. Savings percentages are set using the EnerLume|EM® software (Windows® based) provided. This software allows the user to program changes to savings and "On/Off" as timed events.
Installation
Installation is accomplished by "splicing" the EnerLume|EM® in between the supply feeder and the lighting panel. Suitable for three phase or single phase systems.
Ballast Requirements
The EnerLume|EM® works with either T8 or T12 ballasts. Testing shows that the greatest savings with the least lumen loss are achieved when the EnerLume|EM® is used with single voltage T8 ballasts.
