Vapor Tight High Bay (VTH)

This product is no longer available​

The Vapor Tight High Bay (VTH) combines the innovation of Linmore ParaBars™ with a vapor tight enclosure. The patented ParaBar™ High Bay Light Bar System is comprised of the highest efficacy LEDs mechanically bonded to an extruded aluminum light bar with parabolic, ultra-reflective sides.

The VTH light output and efficacy is unmatched by any other sealed high bay. When the objective is to utilize a high bay lighting system that repels the elements with the least amount of energy and maintenance, and get an industry leading 10-year warranty, the VTH is the clear choice.

Applications: Commercial Lighting, Food Processing Lighting, Industrial Lighting.

Washdown & Wet Location

IP67 rated and NSF certified. Designed to resist wash-down pressures up to 1500psi, ensuring the safety of its electrical components.

Superior Thermal Design

Based on the ParaBar™ Light Bars, featuring high efficacy LEDs mechanically bonded to an extruded aluminum bar for optimal heat dissipation.

Controls & Sensors

0-10V dimming and a broad range of occupancy and daylight sensors available as an option, including wireless controls.
