Re: Mains installation in garden

Fair point, drive with a slightly higher regulated supply and allow
for the drop off.  I think you can get 13.5V regulated so that may
do the trick.  Still have to be careful that the cable is thick
enough to handle those amps though!

The site selling the garden lights had stuff on the effect of
voltage drop off on brightness.  I think it showed an exponential
drop off of brightness with voltage drop hence the reason not to
overextend the LV runs.
