I think the armour would be a bit OTT to be honest - I plan to run the
cable
alongside the irrigation pipes
so http://www.homestead.co.uk/tcjf5005pb.htm would probably be ok!

Any idea if this will be happy with 12v @ 4w

It'll depend on the length you need and the voltage drop you are
prepared to accept but even the 1/0.50mm stuff should be OK for 50W

NB

Just re-read this and realised you said 4w not 4v so you'll only be
using tiny currents
