Yes, because even when full on, dimmers supplied the lamp with a maximum of 92-95% of the full AC voltage and hence provides a slight energy saving. As the lamp is dimmed more, the RMS voltage across the lamp is reduced and the energy saving becomes more. As an example, an incandescent or halogen lamp [...]
