Bless my 80yr old Granddad, he does try his best but sometimes I just wish he would give me a call first.
Went up to his place today to see the family in general and to have a look at an issue with his mobility scooter.
I stumbled upon he had replaced the outside lantern light on one of his sheds with a 8.5W LED PIR flood light
and had used the existing T&E cable with the flood lights round compression gland and had the cores of the T&E exposed and hanging out side the flood light! 
I of course corrected it straight away.
Also, the LED flood light (LivarnoLux brad IIRC) is supposedly double insulated which of course has no facility for an earth connection, but yet has a metal body where live wires enter. I'll take it it is double insulated through out.
