Lighting professionals have spoken... While demonstrating
growing interest for the unique soft-light environment
provided by Alter (pronounced Alt-Air), they increasingly
seek cost-effective lighting alternatives. In response,
Lightolier has engineered a special line of Alter luminaires featuring the highest possible luminous efficacy
(lumens per watt), in addition to Alter’s trademark quality
construction and balanced brightness. This QHE supplement showcases our new selection of Alter High
Efficiency luminaires.
Specular interior optic optimized for maximum visual comfort and balanced
brightness (e.g. all luminaire surfaces have same visual appearance).
✔
Advanced features (e.g. Alter soft white film concealing lamp image,
high-reflectance non-yellowing Alter soft white paint finish, etc.).
✔
✔
Shielding Selection
One-piece microperforated mesh diffuser.
✔
✔
One-piece solid opaque diffuser.
✔
Two-piece microperforated mesh diffuser with narrow open slot for
dramatic and distinctive appearance (solid opaque version also available).
✔
Quantity vs. Quality: How Alter High Efficiency
compares with Alter Classic.
Refined Appearance
Seamless welded forms for clean ceiling lines.
✔
✔
Applications dictate which luminaire is best suited for the
task. In some instances, Alter High Efficiency, with its
promise of superior specification value, will be the clear
choice. At times, Alter Classic may be the better solution.
If you have any doubts, consult your Lightolier representative.
Uncluttered look (no visible hardware).
