PIR Security light

[goooba769]

Im looking to put either a 500w or a 150w PIR security light outside my garage and was looking for some advice on the instalation.
I was going to run a fused spur for the supply and here are my questions-
1. What size fuse for each size light?
2. Should I run the spur off a particular circuit(light circuit or power curcuit)?

Thanks in advance for your advice

A 3A fuse will do for both lights using 1.5mm² cable. You can take the feed from either the lighting or socket circuit so long as it is fused down appropriately.

This work is notifiable unless the cable goes directly through the wall and into the light fitting. Remember that twin and earth is not suitable for outdoor use when it will be subjected to direct sunlight.

I would run the light from a switched spur on the power.

150W = 0.65A

500W = 2.17A.

But I would use a 3A for the smaller & a 5A for the other.

Thanks for the prompt reply and useful info
Its on the garage and there is power just on the other side of the wall so a straight forward run the cable in the garage and then through the wall into the light.

Thanks

Does anyone know roughly how much this job would cost of I got an electrician in?
