BALLASTS
FLUORESCENT
Most of our interior fixtures using compact fluorescent lamping are supplied with
magnetic high power factor (HPF) ballasts that are "Class P" (thermally
protected). These HPF ballasts are rated at 90% (or better) power factor and are encased
and potted style.
Electronic Ballasts are standard for
selected fixtures and are optional on all other fixtures. They are designated by the
suffix "SSB" (Solid State Ballasts). Due to availability by lamp type and
voltage we use several suppliers for electronic ballasts. All the electronic ballasts we
supply meet the following minimum standards:
• Flicker-free starts.
• Class A sound rating
• Power Factor >.98
• Crest Factor <1.7
• Harmonic Distortion <10%
• End of Lamplife Circuitry
Dimming Ballasts are optional for many
of our fixtures. We offer electronic dimming ballasts from several manufacturers,
depending on lamping and fixture size. Some ballasts use proprietary controls or require
"Control Interface" equipment. Compatibility of ballasts must be coordinated
with the control equipment manufacturer. Prices vary accordingly, so check with your Rep
for help with this option.
Please note that all electronic and dimming
ballasts require 4-pin lamps.
EXTERIOR FLUORESCENT
Electronic ballasts are standard for all fixtures included in the Wall Mounted
Exterior and Landscape Sections using compact fluorescent lamping. These ballasts are
rated for outdoor use with a minimum temperature rating of -12° F (25° C), meeting
performance requirements for all but the coldest climates.
Note that fixtures normally intended for
interior use, but desired for damp location, do not come standard with electronic
ballasts. For those fixtures we suggest specifying the optional electronic ballast.
HIGH INTENSITY DISCHARGE
For both high pressure sodium and metal halide lamps, standard ballasts are core and
coil, high power factor (HPF). HPF ballasts are rated at 90% (or better) power factor.
Metal halide ballasts are multi-tap for 120/277 volts, HPS are not. For HPS lamps minimum
starting temperatures are -40° F (-40° C); for metal halide -20° F (-28° C).
Selected fixtures come standard with
electronic ballasts for metal halide lamping. These fixtures are noted in the spec
information. Electronic ballasts provide the following benefits for metal halide lamping:
• High efficiency reduces energy costs.
• Lamp wattage regulation provides rated lamp life with excellent color
consistency.
• Class A sound rating.
