In the UK we already have a dedicated lighting connector, more correctly called a luminaire support coupler. The most commonly used version is known as the "Klik socket", rated @ 6A 250V and used in commercial/industrial installations for final connection of luminaires.
To see a picture of this device go to: www.hager.co.uk and clik on the orange KLIK logo.
