From Part L
Fixed external lighting
Fixed external lighting means lighting fixed to an external surface of the dwelling supplied from the occupier's electrical system. It excludes the lighting in common areas in blocks of flats and other access-way lighting provided communally.
48 When providing fixed external lighting, reasonable provision should be made to enable effective control and/or the use of efficient lamps such that:
a. EITHER: Lamp capacity does not exceed 150 Watts per light fitting and the lighting automatically switches off:
i. When there is enough daylight; and
ii. When it is not required at night; or
b. the lighting fittings have sockets that can only be used with lamps having an efficacy greater than 40 lumens per circuit-Watt.
Compact fluorescent lamp types would meet the standard in (b), but GLS tungsten lamps with bayonet cap or Edison screw bases, or tungsten halogen lamps would not.

I think that covers it but he who is without sin should cast the first stone!

Would not a switch be a better way to turn the light off ?

 

[securespark]

Providing it's 4mm² flex, it'll be OK.

Even if it stretches, it should still have an acceptable csa...

You need a few strokes of the birch, my lad.

 

[bernardgreen]

That's sick, a more aweful comment is hard to imagine

 

[ban-all-sheds]

I'm sorry to cedar fuss I've created.

 

[Stoday]

You need a few strokes of the birch, my lad.

Don't you mean "It's plain yew need a few strokes of the birch, my lad"?

 

[wotan]

If yew got a few strokes of the birch, that would not be poplar.

 

[bernardgreen]

Bit concerned that as the tree grows it may pull the cable out of the box. Would that be dangerous.
