A luminary is classified as having a long light distribution when its max candlepower point falls between 3.75MH 6.0MH TRL. The maximum luminaire spacing-to-mounting height ratio is generally 12.0 or less.

The upper limit of the output current which cannot, by design be exceeded under any conditions.

High voltage lines can be used to transmit R. F. carrier signals for the purposes of voice communication, remote signaling and control. The frequency range from 30 to 500 kHz has proven to be advantageous for high frequency carrier transmission. Line trap

1) The amount of electrical power required by connected electrical equipment. 2) The total impedance of all the items in the output circuit.
