F-6.6
High P ressure Sodium Lamps.
F-6.6.1 High-pressure sodium lamps are a type of high intensity discharge lamp
whose most common applications include roadway lighting, flood lighting, and other
forms of outdoor and industrial lighting. In addition, low wattage (150 watts and less)
versions are used for a variety of indoor and exterior applications.
F-6.6.2 Lighting systems employing high-pressure sodium lamps should be avoided
in the majority of applications. Recent research findings have determined human vision
difficulties under sodium based lamps. Appropriate locations for high-pressure sodium
luminaires include warehousing and similar situations where neither detailed nor close-
up visual work occurs. Lamp warm-up and restrike times should be taken into
consideration, and appropriate instant-starting emergency lights should be provided.
F-6.7
Low Pressure Sodium Lamps.
F-6.7.1 Low-pressure sodium lamps are a type of high intensity discharge lamp
whose most common applications include roadway lighting, and other forms of outdoor
and industrial lighting.
F-6.7.2 Lighting systems employing low-pressure sodium lamps should be avoided in
the majority of applications. Recent research findings have determined human vision
difficulties under sodium based lamps. A ppropriate locations for low-pressure sodium
luminaires include outdoor storage areas and similar situations where security and
surveillance is provided principally by cameras tuned to respond to the monochromatic
radiation of these lamps. Lamp warm-up and restrike times should be taken into
consideration, and appropriate instant-starting emergency lights should be provided.
F-6.8
Sulfur Lamps.
F-6.8.1 Sulfur lamps are an evolving type of high intensity discharge lamp. Sulfur
products have limited availability, but growth in the product area is expected.
F-6.8.2 Lighting systems employing sulfur lamps can be considered in special or
unique applications where the energy efficiency and long lamp life can be realized
without adverse effects. Appropriate locations for sulfur luminaires might include area
lighting and similar situations where a high wattage, point source may be suitable.
Lamp warm-up and restrike times should be taken into consideration, and appropriate
instant-starting emergency lights should be provided.
F-6.9
Cold Cathode and Neon Low Pressure Lamps. Neon and cold cathode
lamps are custom -made low pressure lamps similar to fluorescent lamps in shape, size,
and method of operation. Because of their custom nature, neon and cold cathode
lamps should be avoided except for unique and specialized applications such as signs,
special effects, and shapes such as curves or non-standard lengths.
