LAMP CODES & SPECIFICATIONS

Electrical specifications are determined at a basic temperature of 25°C. Lamp circuit is independent of switch operation.

For dimension drawing of lamps see Accessories & Hardware section.

For neon, if the source voltage is greater than rated voltage, a ballast resistor is required. The ballast resistor calculation and more

lamp detail are shown in the Supplement section. Neon not for use with green lamp cover or blue and green filters.
