shall operate from 50/60 Hz input source with no damage
to the ballast.
Ballast shall be of metal can construction to meet all
plenum requirements and to eliminate the need for extra
grounding wires
Ballasts
shall be a high frequency electronic type, and operate
lamps at a frequency above 40 kHz to minimize interference
Lamp Current Crest Factor (ratio of peak to RMS current)
shall be 1.7 or less in accordance with lamp manufacturer
recommendation and ANSI C82.11-1993.
Ballasts shall tolerate operation in ambient temperatures
up to 55°C without damage.
Ballasts
shall have a maximum case temperature test point of
75°C printed on the label for easy fixture testing and
trouble shooting.
Ballast shall have a maximum case temperature rise of
15°C.
Ballasts shall comply with FCC Part 18 Non-Consumer
Equipment for EMI (power line conducted) and RFI (Radiated).
Ballasts shall provide transient immunity as recommended
by ANSI C62.41-2002.
Ballasts shall operate lamps with no visible flicker
(<3% flicker index).
Ballasts
shall tolerate sustained open and short circuit output
conditions without damage.
Ballasts
shall be listed, Class P, Type 1 Outdoor, and CSA certified
and unless noted otherwise, approved for use in hazardous
locations (Type HL).
Input current Total Harmonic Distortion shall not exceed
10%.
Ballasts
shall have a Power Factor greater than 0.99
The manufacturer shall provide written warranty against
defects in material or workmanship, including replacement,
for three years from date of manufacture.
Manufacturer
shall have been manufacturing electronic ballasts for
at least fifteen years.
Ballast
shall be manufactured in an ISO 9001 Certified Facility.
General Luminaire Specification

luminaire shall be a full cut-off type resulting in
no spill light.
The
luminaire shall be of the type to accommodate a standard
42mm spigot.
The
luminaire shall be fitted with tools free terminals
for the connection of the live, neutral and earth connections.
It
shall be fitted with an isobaric seal between compartments
to prevent pressure build up between the IP66 compartments.
The
fitting shall be designed with an internal daylight
switch and internal 500mA circuit breaker as optional
extras.

luminaire shall have a maximum weight of 5kg.
The
reflector shall be of a multifaceted type and the whole
inner area of the luminaire housing must be an integral
reflector with a minimum reflectance of 92%.
The
luminaire shall be fitted with automatic power disconnection
to the lamp terminals on opening.
5
stainless steel clips will secure the lid of the luminaire.
All
metalwork of the luminaire will be stainless steel.
The housing, base and bulkhead will be manufactured
from a mineral filled UV stabilized Polypropylene while
the reflector and lamp holder shall be of polycarbonate.
The
lens must be constructed of an acrylic polymer with
lifelong guarantee against dis- coloration.
The
luminaire must be about 695 mm long, 400mm wide and
170mm deep.
Light
Output Requirement
