High Performance Energy-Saving T8 Louvered

ES8P provides a high-performance T8 (HPT8) energy-saving alternative to 3-lamp, 18-cell parabolic fixtures. Used in place of parabolics, ES8P can provide 44% energy savings while meeting IESNA recommended illuminance levels. Ideal for retail, educational, and commercial applications requiring lighting power density as low as 0.6 watts/square foot. 2'x4', 2'x2' and 1'x4' sizes available to meet most general illumination layouts.

Designed and optimized for use with high-lumen T8 lamps and energy-efficient electronic ballasts.

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


Robust design, precision-tooling, and automated assembly combine to create the industry's strongest louver. Rotary sockets provide for simple lamp insertion and positive engagement into lamp contacts. Mechanical light seal requires no foam gasketing. Integral T-bar clips secure fixture to T-bar system. Housing formed of cold-rolled steel.

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.

Consult factory for air version configurations.


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, instant start, =10% THD, universal voltage and sound rated A.

Optional programmed start and step-dimming ballasts available.

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