Max section length of 12ft (8ft max option available). dditional fixture lengths are available - please consult factory. ll lengths are nominal. ctual sizes are one inch shorter than nominal to allow easy in-grid installation. For Gypsum or Flangeless installations add 1 inch to overall fixture length. Refer to ceiling type section of specification sheet and submittal drawings for actual sizes. orners and Transition Pieces orners and other transition pieces are fully luminous and contructed using precision mitered frame and lens components. The frame is welded to ensure a precise and robust assembly. Standard horizontal and vertical corners as well as custom corners are available. Please consult online linear configutor or the factory for precise corner locations and for ordering. lternative transition pieces such as T s, Y s, X s, etc. are also available. Snap-In Lensing Options Satin Flush - Flush, high diffusion glare-free lens Satin Proud - 1 Proud, high diffusion glare-free lens symmetric - Flush, low-glare symmetric lens Flush options ship with our patent-pending underlens solution, while the proud lens ships with an injection molded end cap to eliminate light leak. Reflectors Precision formed cold-rolled steel reflectors with high reflectivity (standard) and ultra-high reflectivity (used with High Performance light engine). Lumen Maintenance 90% (L90) of initial light output at 100,000+ hrs. 70% (L70) of initial light output at 400,000+ hrs, reported L70 >60,000 hrs. Derived from TM-21 ambient and typical operating conditions. onsult factory for additional data. ustom Lumen Output You can select a custom lumen output for your application in Lumens per foot (e.g. -725D for 725 Lms/ft down). Desired output must with within the total light output range. Please contact factory for custom lumen output when not selecting the standard 0-10V DD Driver. TOTL LIGHT OUTPUT RNGE (lms/ft) T 80RI 90RI 2700K N/ K K K If your requirement is expressed in power consumption (W/ft) rather than light output, you can use the power to lumen output curves to convert power consumption to light output for specification. Efficacy for custom lumen outputs can be estimated using lumen output curves or with the use of our online custom lumen output tool. Electrical Dimming provided as standard - dimming wires are capped with wire-nuts for non-dimming applications. Optional battery backup options provided. Default battery location is internal to fixture to reduce field wiring with pre-wired external test switch. Default emergency section is 4ft in length and located at the beginning of the fixture unless designated elsewhere using our linear product configurator tool. To estimate lumen output from the emergency section, multiply battery wattage x minimum fixture efficacy from performance table below (e.g. 14W x 116 lm/w = 1624 lms). Our ETS-DR option will provide switching for both power and dimming wires for applications requiring a UL924 transfer device. Integrated Sensors Please reference page 5 for details.
