Luminosity and Lamp life
extension
using the Active ES Electra™ Lighting Controller
This chart illustrates an example of both the improved lumen
output and the extended lamp life experienced when using the
Electra lighting controller on typical HID lamps.
-
The Baseline (green)
is the manufacturers rated life of a typical HID lamp. In this
example it is 20,000 hours. NOTE:
Manufacturers' definition
of Rated lamp life is that only half the lamps in use will
achieve this length of time, while the other half drop out
at various
points prior to this time. And the lamps that are still
lit by the end of their rated life are operating as low as
50% of
their
original luminosity. The Thick Black line indicates the
resulting minimum lumen output as expressed by the manufacturer.
The
red line indicates the end of their rated life, and the lamps
extinguish
soon thereafter.
-
The Blue line shows that although the Electra-controlled
lamp begins at a lower lumen output, it is still well above
the “designed
Lumens” specified by the manufacturer (purple line)
, and because the lamp burns at a lower temperature, it retains
a better
luminosity and lasts up to 40% longer than the uncontrolled
lamp. Therefore for about 80% of the lamps life, the Electra-controlled
lamp is actually BRIGHTER than the uncontrolled lamp.
