Overview Tu-wire ballasts are primarily intended for retrofit applications where fluorescent dimming must be achieved without changing the existing switching wiring scheme. Tu-wire ballasts require only two input wires (hot and neutral), used both for power and dimming control. Tu-wire ballasts offer high performance dimming from 00% down to 5% for linear and compact fluorescent lamps. eatures ontinuous, flicker-free dimming from 00% to 5% -wire line voltage control for wiring simplicity Models for T4 compact and T8 lamp types Programmed rapid start design will preheat lamp cathodes before applying full arc voltage Lamps turn on to any dimmed level without flashing to full brightness in (5 mm) high, low-profile design for use in low-profile architectural fixtures requency of operation ensures that ballast does not interfere with infrared devices operating between 38 and 4 kz nrush current limiting circuitry eliminate circuit breaker tripping, switch arcing, and relay failure nd-of-lamp-life protection circuitry ensures safe oper-ation throughout entire lamp life cycle for T4 lamps Ultra quiet operation Protected from shorts between any one lamp lead and ground Low-line voltage protection circuitry prevents damage to the ballast or lamps if the ballast is connected to an incompatible dimmer 00% compatible with all Lutron -wire fluorescent controls 00% performance tested at factory esigned and assembled in the U.S.. allasts that dim T4 compact fluorescent lamps are intended for factory installation by OM fixture manufacturers 5-year limited warranty with Lutron field service commissioning (3-year standard warranty) from date of purchase, case type 3.00 in (76 mm) W x.00 in (5 mm) x 4.90 in (4 mm) L, case type 3.00 in (76 mm) W x.00 in (5 mm) x 6.75 in (7 mm) L, case type.8 in (30 mm) W x.00 in (5 mm) x 8.00 in (457 mm) L 369-60c 06.04.

Lamp Sockets Quality lamp sockets are required to ensure positive lamp-pin to socket contact. T8 lamps require knife-edge sockets. U-bent lamps require locking sockets and proper lamp support to hold lamp pins in full contact with the socket. Lamp Mounting Many fluorescent lamp sockets are available with mounting slots to vary the height of the lamp away from the grounded metal surface. aving a fluorescent lamp too close to the grounded metal will reduce lamp life. aving a fluorescent lamp too far away from the grounded metal will make the lamp flicker or not turn on at all. Please note that all of the lamp heights are measured between the grounded metal surface and the glass wall of the lamp.
