Lens selection by application
The Albeo™ ALC4-series optical lens system enables LEDs to provide precise illumination where needed. Lenses are
designed for commercial & industrial applications where mounting height, fixture spacing & light levels help determine lens
selection. The following table outlines lens options and suggested application. Consult factory for specific project layouts.
