Hi Richard;
watts=(volts)(amps)
power=(volts)(current)
watts=joules/second
As you may already know, joules is a unit of work.
As either the voltage and/or level of current increases, so too does the wattage.  Henceforth, the brightness, amount of work, performed by the light proportionately increases.
