OK,
Usually here, most people just want a few 150W PAR-38 lamps to illuminate a few trees and other features of thier gardens.
Our Regs and ECP's here require that an RCD be fitted to any circuit that extends beyond the boundary of the house, it's been that way since the '92 Regs came in.
Generally, all outdoor wiring is required to be wired in 1.5mm2, regardless of length of run and a 10A RCBO protecting it.
With respect to installation methods, I like to install ground-mounted Dichroics with the integral Transformer.
These should be IP67 units though.
I really feel guilty about ripping up a new lawn to install the conduit and Signal Strip that goes with these systems and also the fact that the excavator is none too kind to the other parts of the lawn either!.
But, what is the best type of Outdoor fitting that you guys have installed recently?
I find the 150W PAR-38 fitting OK, but I also hear lots of complaints about the Glare from them.
Final question, what would be your "dream" lighting system?
