Use Sceptalight fixtures in all types of indoor or outdoor agricultural, marine and industrial applications.
Typical applications include:

The fixtures are ideal for illuminating walkways, bridges, tunnels, refrigeration coolers and task areas where corrosion of
metallic fixtures are a concern – like the food processing industry and car washes. They are also well suited for security,
warning, deterrent, directional or general-purpose area lighting. ‘Hazardous Location’ ratings permit use in many industrial
applications as well.

APPLICATIONS

Wet Location Use

Wet Locations are defined as locations in which liquids may
drip, splash or flow on or against electrical equipment. This
can include places subject to saturation with water and other
liquids such as vehicle washing areas and unprotected
locations exposed to weather.

Marine Location Use

The marine location certification, UL 1598A, is a
supplemental approval to the wet location standard that
allows the luminaires to be used in salt water environments.
The standard specifically evaluates for conditions such as
salt spray corrosion, ignition protection, UV exposure and
water ingress. (Not applicable to LEDs)

Class I: In Class I locations, flammable gases or vapors are or
may be present in the air in sufficient quantities that they
may ignite or become explosive.

Class II: In Class II locations, it is the presence of
combustible or electrically conductive dusts that pose the
hazard.

Division 2: In Division 2 locations, the potential hazard is
confined in containers or in a closed system and/or the area
has positive ventilation that normally prevents the gases,
vapors or dusts from reaching ignitable concentrations.

Explosive characteristics of gases, vapors or dusts vary with
the specific material; it is therefore necessary that
equipment installed within the hazardous location is
identified for the specific group of gas, vapor or dust for
which it is approved.

Hazardous Location Use

Sceptalight fixtures are listed and approved for
‘Hazardous Location’ use in:

Class I, Div. 2 Groups A, B, C, & D
Class II, Div. 2 Groups F & G

The following information is provided as an overview of
Hazardous Location environments only. Refer to the NEC for
the complete requirements of Hazardous Locations.

The determination of a Hazardous Location (Class and
Division) is the responsibility of the project engineer just as
it is the installer’s responsibility to be both knowledgeable
and certified to perform work in hazardous locations. Always
consult with the local electrical inspection authority
regarding appropriate use and installation of products.

Hazardous Locations are areas classified according to the
nature of the hazard and divided into divisions that further
define the potential hazard based on conditions that exist.

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/mil2.

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).
