The main difference between the luminous efficacy of radiation and the luminous efficacy of a source is that the latter accounts for input energy that is lost as heat or otherwise exits the source as something other than electromagnetic radiation. Luminous efficacy of radiation is a property of the radiation emitted by a source. Luminous ...
Electro-magnetic radiation emission Can emit a small amount of X-ray radiation. Only emits non-ionizing radiation. [39] Emits strong radio frequency electromagnetic radiation [40] None, although control circuitry may emit radio interference Size Up to 43 in (1.1 m) [41] Up to 120 in (3.0 m) [42] Up to 150 in (3.8 m) [43] (152 in experimental) [44]
Energy of electromagnetic radiation. Radiant energy density: w e: joule per cubic metre J/m 3: M⋅L −1 ⋅T −2: Radiant energy per unit volume. Radiant flux: Φ e [nb 2] watt: W = J/s M⋅L 2 ⋅T −3: Radiant energy emitted, reflected, transmitted or received, per unit time. This is sometimes also called "radiant power", and called ...
