If it is not double insulated then it should be earthed with an earth cable which connects the fitting to the means of earthing at the origin of the installation.

Where does the earth wire go in a light fitting?
The earth wire or neutral should be connected to the shell of the lamp holder. The hot should be connected to the center contact of the lamp holder. The reason for connecting the earth wire (neutral) to the shell is so you don't make contact with the hot while removing or installing a lamp.
What happens if my light doesn't have an earth wire?
Your lamp will still work without an earth connection, However if the lamp has exposed metalwork and does not display the symbol for double insulation (a rectangle within a rectangle) then most countries wiring regulations expect an earth connection to be provided.
