Reputable lighting manufacturers
will guarantee the light levels
presented in their light plans—
provided the luminaires are installed
in accordance with the recommended
plan, of course. If you are comparing
light plans from multiple lighting
suppliers, be sure that the data
being presented to you is a true
indication of the actual performance
you can expect. A new lighting
system is a big investment and can
significantly impact your yield, so
ask questions. Is the proposed light
output of the luminaire based on the
lamp’s maintenance factor (end of
life) for the best indication of actual
performance? Does the light plan
include reflectances? If it does, it
can be used to artificially boost the
projected light levels.
Application example # 2 of how the dimensions of the grow facility and the crop
can affect the luminaires and reflectors specified in the light plan.
This second example shows a facility with limited ceiling height. In this application,
P.L. Light Systems’ NXT-LP luminaires with the Alpha reflector were specified in the
light plan, as the low profile housing is specifically engineered to allow for more
space between the luminaire and the surface of the crop. Again, the luminaires along
the walls were equipped with the Asymmetric reflector to prevent the light from
being directed onto the walls where it would be wasted.
