High Performance Energy-Saving T8 Louvered

Companion fixture to the ES8 2'x2' and 2'x4' versions. ES8P 1'x4' provides a high-performance T8 (HPT8) energy-saving alternative to traditional 3" parabolics. Improves the balance between horizontal and vertical light levels. Ideal for use in corridors, small spaces or continuous row mounting in retail, commercial or educational applications.

Designed and optimized for use with CEE (Consortium for Energy Efficiency) qualified, high-lumen T8 lamps and energy-efficient electronic ballasts.

Highly reflective surfaces, in conjunction with efficient design, produce up to 86% photometric efficiency and a Luminaire Efficacy Rating (LER) of up to 86 using listed lamps and ballast.


Robust design and precision-tooling combine to create the industry's strongest louver. Rotary sockets provide for simple lamp insertion and positive engagement into lamp contacts.

Finish: Five-stage iron-phosphate pre-treatment ensures superior paint adhesion and rust resistance. Housing painted after fabrication with environmentally friendly, high-gloss, very high reflectivity polyester powder-coat. Louver painted after fabrication with low-gloss, high reflectivity polyester powder coat.


Mechanical shielding is provided with angled length blades, and linear faceted cross baffles. Contoured housing efficiently directs light downward. Lamp cut-out maximizes shielding even in shallow plenum applications and softens light distribution to deliver a balanced amount of light to both vertical and horizontal surfaces.


Standard ballast is high-efficiency, CEE qualified, instant start, =10% THD, universal voltage and sound rated A.

Ballast disconnect provided standard where required to comply with U.S. and Canadian electrical codes.

Optional program start ballasts available.
