Abstract

Determining an amount of light output from a solid state lighting (SSL) unit based on a dimmer setting includes determining the dimmer setting of the dimmer during a readout mode by analyzing a power signal received from the dimmer the dimmer setting indicating a desired level of light determining power needed at input terminals of the SSL unit for an SSL load to output the desired level of output light and determining a value of an adjusting signal for adjusting the power at the input terminals of the SSL unit during a power reception mode based at least in part on the determined dimmer setting causing the SSL unit to output the desired level of light.
