Construction & Mounting

Extruded aluminum housings are supplied in nominal lengths of 2 ft- 8 ft. Fixtures may be continuously rowed (contact factory for details). Easy access to remote driver and LED boards. End caps are extruded aluminum.
Integral powder-coated LED housing with excessive reflectivity for increased focused direct lumen output.
Standard powder-coated colors are white, black, and silver. Custom processed wood finishes, aluminum anodized finishes, chrome/gold plating, and custom finishes are available as well. We also accept RAL and Pantone numbers for powder-coating color choices. (except for louver, always black)
Extruded snap-in black microcavity optics formulated for LED light sources.
Cable mounting supports and powers the Sienna 1 MCO because it's too small to fit a driver. Can also be powered via low gauge 2 wire with cable grippers. Various size canopies and different power supplies are available. The cable uses gripper-style locking for field adjustments. Canopy mounts to standard J-box and the standard cable lengths are 4 feet.
UL Approved

  • Rated life (90% survivorship) of 50,000 hours at 50º C max. ambient (and 70º C max. case) temperature. At maximum driver load: Efficiency >84%, PF>0.9, THD<20%.
  • We use only recognized brand LED's with 3 SDCM (standard deviation color matching) with high color consistency. 2 SDCM available upon request.
  • Our LED drivers feature HPF (high power factor), universal voltage 110 - 277 VAC and include 0-10V dimming.
  • Remote emergency drivers are an option, long life, high temperature, recyclable Ni-Cad battery pack with test switch and charge indicator. EMR is a minimum of 90 minutes operation to meet code.
  • POE - We are working with Molex/Igor POE systems. We can add a POE driver into our fixtures or remote them. Based on the fixture you select, we will notify you (or you can contact the factory) to see if we can install the P-driver or the P-driver needs to be remote. Just add POE1 in the spec and we will advise. Please keep in mind you need to specify a complete POE control system before specifying POE1.
