Lighting: What does dual insulated mean?

[miljee]

My mother's house was recently assessed for electrical safety. The report said she needed to replace a couple of wall and ceiling lights but they need to be 'dual insulated'. What does that mean? Can any light be dual insulated or do you have to source special ones?

She also will be getting a new fuse box (consumer unit?!)

I know nothing of electrics! (Can you tell?!)

It means she hasn't got any earthing on her lighting circuits and should only use 'Class 2' (double insulated) light fittings like these - http://www.double-insulated-lighting.co.uk/?gclid=CIPm74XRkacCFQ8f4QodgCBBcw

There will be issues with a new consumer unit installation if there's no earth cable (CPC) on the lighting circuits too, her electrician should explain this all in detail.
