Tested according to IES procedures. Test distance exceeds five times the greatest luminous opening of luminaire. Dec. 8, 2004
All of the ballasts offered include an Auto Restart after
Hot feature, which allows the lamp to be pulled out and
replaced while the power is still on and the lamp will
re-strike automatically. The Total Harmonic Distortion (THD)
for all ballasts is less than 15%.
Dielectric Strength
Dielectric strength is the measurement (in volts per mil) of
the maximum electric field strength an insulating material
can withstand intrinsically without breaking down (i.e.
without experiencing failure of its insulating properties).
Rubber, one of the better insulating materials available,
offers a good example for comparing dielectric strength.
Evaluating values on a 1/8
"
thick sample, the dielectric
strength of general purpose rubber is ~400 V/mil

while the
dielectric strength of PET material (Rynite) is 355 V/mil

.
Installation
The ceiling and wall mount boxes each have four 3/4
"
threaded hubs with liquid-tight knockouts. Two feet are
spaced at 5-1/4
"
for base up installation. Pendant mount
fixtures have a single 3/4
"
threaded hub. The minimum
supply wires must be rated as shown below:
It should be noted that the Wet location light fixtures require
minimum 60°C supply wires; however, the label on the
fixture states that minimum 90°C supply wires must be
used. If requested by a customer, a letter of certification
supporting this fact can be provided.

Temperature Codes
The temperature marking, specified by the T code on the
fixture label, indicates the maximum surface temperature of
the specific electrical equipment. In Class I Hazardous
Locations, equipment shall not be installed in an area where
vapors or gases are present that have an ignition temperature
less than the maximum external temperature rating of the
equipment.
• Incandescent – Temperature Code T2B 500ºF (260ºC)
• Fluorescent
– Temperature Code T3A 356ºF (180ºC)
Threaded Hub Connection
Many of the diverse threaded conduit fitting products are
tapered to ensure tight connections are made. To avoid
potential for stress cracking as a result of over-tightening,
install the terminal adapter fitting into the hub 1/2 turn past
hand-tight. Teflon
®
tape or Teflon
®
pipe dope may be used to
ensure a watertight connection.
Compact Fluorescent Lamps
The compact fluorescent lamps provided with the
Sceptalight fixture have either 2 pins or 4 pins. Each 2-pin
lamp has an internal starter and is designed for preheat,
magnetic operation. The 4-pin lamps are designed for
electronic ballast operation and do not have an internal
starter; starting the lamps is a function of the ballast
provided with each fixture.
Ballasts
Sceptalight 18W and 26W fluorescents include high power
factor electronic ballasts with inherent thermal protection for
a minimum start temperature -13°F (-25°). Also, these
ballasts have an end-of-life (de-active lamp) protection
circuit to prevent damage to the light fixture components
from potential high current flow. At start-up, fluorescent
fixtures require a high current, which stabilizes once the
lamp is lit. However, if the lamp is broken or burnt out, the
high starting current could cause damage to the electrical
components of the fixture.
Sceptalight 7W, 9W and 13W fluorescents include normal
power factor (typically 40-60%) magnetic ballasts with a
minimum start temperature of 50°F (10°C).
