L T5 lamps with full

SYSTEM PHO High Ambient
Temperature ballasts are specifically
designed for applications where the
ballast is subjected to higher ambient
temperatures, as in high bay indus-
trial installations. The four lamp UNV
(120-277V) ballast system provides
18,600 mean lumens, which, when
factoring in lumen maintenance and
typical T5HO fixture efficiency, can be
considered as a direct replacement
for standard 400W MH. As such, the
family is ideally suited to replace
250W and 400W metal halide installa-
tions.
Unique to the family is the 120-277V
4-lamp “switching” ballast, designed to
switch from 4- to 2-, 3- to 2-, 3- to 1- or
2- to 1-lamps. The switching feature can
be accessed through a second input power
terminal. This feature allows for a range of
control interfaces, including an occupancy
sensor, mounted inside a fixture.
SYSTEM PHO HT ballasts contain QUICK-
SENSE
®
ballast technology, a patented
circuitry designed to shut down the
system reliably and safely when lamps
reach end-of-life.
Setting the standard for quality, SYSTEM
PHO HT is also covered by our QUICK 60+
®
warranty, the first and most compre-
hensive system warranty in the industry.
SYSTEM PHO HT is available in four and
two lamp models to cover a wide range
of applications.
System PHO HT operates on 120V
through 277V, 50 or 60Hz current, elimi-
nating “wrong voltage” wiring errors and
reducing the number of ballast models in
inventory by half.
PROStart ballasts provide optimum starting
conditions and provide up to 100,000
switching cycles for use on occupancy
sensors and building control systems.
QUICKSENSE ballast technology helps to
protect against overheated bases and
sockets, as well as cracking of the lamp
glass wall, and uses dynamic end-of-
lamp-life sensing to avoid false
shutdowns caused by some static
sensing methods. QUICKSENSE ballast
technology will auto reset when spent
lamps are replaced with new ones.

The four lamp unit can be wired for four,
three, two or one lamp operation. The
two lamp unit can be wired for one lamp
operation, allowing for an additional 50%
reduction in inventory model numbers.
SYSTEM PHO HT has a 25.4H (mm)
profile. PENTRON T5 lamps are designed
to provide peak performance at 35°C
fixture ambient, allowing for smaller and
more innovative fixtures.
