The data
gathered enabled us to make a comprehensive analysis of the three technologies.
The result was that in the areas where the metal-halide lamps and Bayled were
installed, the lights were switched on at full power throughout the day, and
the two luminaires could not be adjusted or controlled. It should be emphasised
that even though both systems were switched on 100% during the entire working
day, major energy savings of 50% were still made with the Bayled and metal-halides,
as well as a significant increase in constant brightness of up to 270 lux (an
increase of 17% luminosity due to the use of Bayled lamps).
By
comparing the metal-halide lamps (400 W) with the Smart Bayled (200 W) installed,
we achieved energy savings of 82%. When the working day begins, the level of lighting
on the ground is 270 lux (with the Smart Bayled switched on). As the day
progresses, as it gets lighter and light enters the warehouse’s skylights, the Smart
Bayled luminaires reduce the intensity of the light until they are switched off. Throughout
the afternoon, as less natural light enters through the skylights, the Smart
Bayled luminaires come on gradually, meaning that there is always the same
level of brightness on the ground.
The installation
of Smart Bayled luminaires resulted in significant savings in energy and
maintenance costs in the installations.
