描述：The 4" adjustable wafer with 5CCT Switchable White technology provide high-quality light output and efficiency featuring a switch for easy color temperature adjustment to choose between 2700K, 3000K, 3500K, 4000K, or 5000K - while eliminating the need for recessed housings. The adjustable gimbal allows for up to 20 degrees of rotation making this version perfect for angled ceilings.HOUSING:Polycarbonate 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" and 6" 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 and 6-1/4" for the WF6 ? Can be installed from 3/8" to 1 ?" ceiling thickness ? Can be removed from below the ceiling for service or replacement.LED LIGHT ENGINE:Switchable 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 dimmers.DRIVER:Connect 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 with integrated inside steel remote box has 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 ? 2" plenum space required for the installation of the WF6 driver box, and 3"plenum space required for the installation of the WF4 driver box ? Suitable for installation in t-grid and drop ceiling applications with universal new construction pan.OPTICAL SYSTEM:Edge-lit LED technology uses light guided plate to distribute light ? Polycarbonate lens provides even illumination throughout the space ? Efficient system that can produce over 729 lumens while using 10W (WF4) and 1007 lumens while using 12W (WF6) ? Replaces 65W incandescent (WF4) and 75W incandescent (WF6).
