Lutron HL3-T426-277-1-S Hi-Lume FLUORESCENT DIMMING BALLAST 277V 1-Lamp 26W CFL For Sale

LUTRON HI-LUME 1% FLUORESCENT DIMMING BALLAST

ARCHITECTURAL DIMMING BALLAST

FEATURES: • Continuous, flicker-free dimming from 100% to 1%

• Standard 3-wire line-voltage phase-control technology for consistent fixture-to-fixture dimming performance

• Models available for T4 triple-tube compact and T5-HO linear lamps

• Programmed rapid start design preheats lamp cathodes before applying full arc voltage

• Lamps turn on to any dimmed level without flashing to full brightness

• Low harmonic distortion throughout the entire dimming range maintains power quality

• Frequency of operation ensures ballast does not interfere with infrared devices operating between 38 and 42 kHz

• Inrush current limiting circuitry eliminates circuit breaker tripping, switch arcing, and relay failure

• End-of-lamp-life protection circuitry ensures safe operation throughout entire lamp life cycle

• For linear lamps, ballasts maintain consistent light output for different lamp lengths, ensuring fixture uniformity

• Ultra-quiet operation

• Protected from miswires of any input power to control lead, or from lamp leads to each other and/or ground

• 100% performance tested at factory

• 5-year limited warranty with Lutron field service commissioning (3-year standard warranty) from date of purchase

• Ballast Factor: Greater than .95 for T4 lamps, equal to 1.0 for T5-HO lamps

• Power Factor: Greater than .95

• Total Harmonic Distortion (THD): Less than 10%

• Maximum Inrush Current: 7 amps per ballast at 120V, 3 amps per ballast at 277V

ENVIRONMENT: • Minimum lamp starting temperature: 50°F (10°C)

BALLAST WIRING & MOUNTING: • Ballast is grounded by a mounting screw to the fixture

• Power and lamp wiring terminals accept only one 18 AWG solid wire per terminal

LAMP SEASONING: Refer to the lamp manufacturer’s recommendations for lamp seasoning requirements prior to dimming.

BALLAST/SOCKET LEADS: • Lead lengths from ballast to socket must not exceed 7 ft. (2 m) for T5-HO lamps

• Lead lengths must not exceed 3 ft. (1 m) for T4 compact lamps

LAMP SOCKETS: Lamp sockets as per IEC 60400 are required to ensure positive lamp-pin to socket contact. T5 linear lamps require rotary locking sockets.

LAMP MOUNTING FOR T5 & T5-HO: • Keep lamps 3/8 in. ± 1/8 in. away from grounded metal surface

• Having a T5-HO lamp too close to grounded metal may cause a visible difference in brightness along the length of the lamp

BALLAST OPERATING TEMPERATURE: Ballast case temperature must not exceed 75°C at any point on ballast.

WIRING & GROUNDING: Ballast and lighting fixture must be effectively grounded. Ballasts must be installed per national and local electrical codes.
