描述：HousingPolycarbonate injection molded outer frame, with steel back plate. Non-conductive dead-front trim design suitable for a wide range of applications and codes requiring a non-conductive lens ? FT4 3-pin plenum rated cable connector to connect from module to remote driver box ? Steel spring clip for easy installation. 4", 6" or 8" cut out template is provided to ensure a correct sized hole is cut into ceiling for proper installation of the trim. Size of hole should not exceed 4-1/4" for the WF4, 6-1/4" for the WF6 and 8-1/4" for the WF8 ? Can be installed from 3/8" to 1 ?" ceiling thickness ? Can be removed from below the ceiling for service or replacement.LED Light EngineSwitchable white color temperature from 2700K, 3000K, 3500K, 4000K, 5000K ? 90 CRI minimum ? Color accuracy within 4 step McAdams Ellipse at the end CCT (2700K and 5000K), within 6 step McAdams Ellipse in the middle CCT (3000K, 3500K, and 4000K) ? Dimming 100% to 10% with most standard incandescent dimers (see list of approved dimmers).DriverConnect directly to 120V Class-2 (CAN ICES-005 (B) / NMB-005 (B)) LED driver ? 120V 60 Hz constant current driver provides noise free operation ? IC rated driver with convenience of a switch to choose between 5 selectable color temperature options ranging from 2700K (warm white), 3000K, 3500K, 4000K, or 5000K (daylight) ? The isolated driver integrated inside steel remote box with four 7/8" knockouts with slots for pryout. Suitable for pulling wires with the 12 cubic-inch wiring compartment to accommodate up to (6) 14 gauge insulated conductor or (4) 12 gauge insulated conductors, making the Wafer LED Downlights much easier to wire in 2in/2out (plus ground) daisy-chain applications and contractor friendly ? 2" plenum space required for installation of the remote driver box ? Suitable for installation in t-grid and drop ceiling applications with universal new construction pan.Optical SystemEdge-lit LED technology uses light guided plate to distribute light ? Polycarbonate lens provides even illumination throughout the space ? Efficient system that can produce over 670 lumens while using 9W (WF4), 970 lumens while using 13W (WF6) and 1640 lumens while using 19W (WF8) ? Replaces 65W incandescent (WF4), 75W incandescent (WF6) and 100W incandescent (WF8).LifeRated for 50,000 hours at 70% lumen maintenance.LabelsCSA certified to US and Canadian safety standards ? ENERGY STAR?certified product ? Suitable for wet location ? Air-Loc certified in accordance with ASTM E283-2004 ? NOM Certified ? Can be used to comply with California Title 24 Part 6 High Efficacy LED light Source Requirements ? U.S. Patent No. 10,681,784.
