A luminary is classified as having a short light distribution when its max candlepower point falls between 1.0MH 2.25MH TRL. The maximum luminaire spacing-to-mounting height ratio is generally 4.5 or less.

1. A load that occurs when at ungrounded conductor comes into contact with another conductor or grounded object. 2. An abnorman connection of relatively low impedance, whether made intentionally or by accident, between two points of different potential.

A dangerous electrical condition associated with the possible release of energy caused by contact or approach to energized parts.
