LSI announces the official launch of its latest innovation, the Alliance™ LED High Bay (ALI). This original, American-manufactured and designed luminaire distinguishes itself as Best-In-Class across many criteria important to specifiers and design-build contractors. The maximum efficacy across these 2 foot and 4 foot fixtures is an impressive 163 lumens per watt. But more impressive are the numerous configurable attributes that make LSI Alliance High Bays easy to specify, such as 16 standard lumen packages, programmable drivers for custom lumen packages, and multiple distributions, lenses, CCTs, mounting alternatives, emergency backup options and controls choices. This makes LSI Alliance LED High Bays flexible for use in applications from school gymnasiums to industrial facilities and more. Optional decorative end caps also expand the settings in which the Alliance can be an ideal choice.
