Downlights can be mains powered or low voltage (typically 12 volts) - see article 'low voltage' does not mean 'low energy'

Typically mains bulbs used are 35 or 50 watt while low voltage systems use 20-50 watt - each giving similar levels of illumination.

Halogen bulb, mains and low voltage downlights can be dimmed using normal light dimmers, althought with low voltage you must make sure that your transformer is compatibile with the dimmer switch.
