night into day with Electrophysics’ ALS-20 infrared
illuminator. Unlike IR filtered incandescent illuminators
or an IR LED, the ALS infrared illuminator uses
a solid-state laser diode that delivers high efficiency
and extremely long service life. The ALS-20 infrared
illuminator produces even illumination edge-to-edge.
The standard unit is offered with a horizontal light
beam angle of 20° and a vertical beam angle of 10°.
Optional beam angles are available between 10° and
80° and illuminate over 15 square acres per ALS
device. One ALS-20 can replace the light produced
from several outdoor poles of stadium lights. Initial
costs, maintenance, and electricity savings can
be realized with the installation of one of our
