HID LAMP INFORMATION
TYPES OF HID LAMPS
HID stands for “High Intensity Discharge”, a general term for:
• High Pressure Sodium (HPS)
Metal Halide (MH), (CMH)
• Mercury (H), (SBMVL)
•
Recent developments have produced new lamp
designs which have brought about improvements in
life, color rendering, and lumen maintenance.
LAMP CHARACTERISTICS
HID lamps provide extremely effi cient illumination
in a large area. Lamp characteristics, however, vary
according to use. Figure 1 shows the characteristics
of the three basic HID lamp types according to
the following variables:
• Lamp E� cacy (Lumens Per Watt)
Color Rendering Index (CRI)
• Correlated Color Temperature (CCT) Kelvin
•
MAIN FEATURES
High Lamp E� cacy - low power expense
High Lamp Lumens - minimal investment
Long Life - inexpensive maintenance

Lamp Operating Positions
Lamps must be operated in their specifi ed operating positions in order
to maximize lamp performance and life. Incorrect operating positions
may also create the possibility of a lamp rupture. Because of these
factors it is imperative that users adhere to the specifi ed operating positions
and fi xture requirements. The following chart shows the correct
lamp operating positions based on the Position Code Letters which are
contained in the lamp description.

FIXTURE REQUIREMENT CODES
O = Open fi xture permissible. Lamps can be
operated in an open fi xture within the lamp’s
specifi ed operating position limits.
S = Open fi xture permissible with operating
position restrictions.
E = Enclosed fi xture required. Lamps must
be operated in an enclosed fi xture.

As stated in the 2005 NEC directive, TYPE-S lamps will continue to be available for use in existing installations that use
open luminaires. Open luminaires using TYPE-S lamps remain safe and eff ective lighting alternative for many applications
when operated in accordance with manufacturer’s warnings and instructions. TYPE-S lamps will not be an option for open
luminaires in future new construction or in major lighting renovations to existing buildings.
EYE Lighting off ers O-Rated, Protected Metal Halide (MP) lamps with shrouded arc tubes and the required EX39 Mogul base
that meet the 2005 NEC directive for use in Open Fixtures. EYE Lighting also off ers TYPE-S lamps for operation in existing
Open Fixtures when operated according to listed warnings and operating instructions.
