Consistency
Monolight consistency refers to the power output of the unit from flash to flash. Good monolights will vary little from one flash to another. Monolights that vary greatly (more than 1/5 of an f-stop) are said to be inconsistent. Inconsistent monolights makes computing the appropriate aperture next to impossible due to the variable light output.
Since monolights often vary the capacitor charge to vary the light output, lower voltage through the tube can affect the flash's color temperature. Some units have electronics to compensate and maintain a steady color temperature through the power range.

Famous quotes containing the word consistency:
“The lawyer’s truth is not Truth, but consistency or a consistent expediency.”
—Henry David Thoreau (1817–1862)
“All religions have honored the beggar. For he proves that in a matter at the same time as prosaic and holy, banal and regenerative as the giving of alms, intellect and morality, consistency and principles are miserably inadequate.”
