Turn 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 ALS-20 illuminators.
