Modified linear curve
A modified linear curve reduces the voltage change at low control levels for better performance in low-
wattage fixtures.

Square law curve
At low control levels, much of a traditional incandescent fixture's light output is in the invisible infrared
spectrum. This results in poor visible response to low control levels. A square law curve applies a
multiple derived from the square root of the control level (with full output equal to 1.00) to increase
voltage response at low control levels to compensate for the infrared loss.
