Can I run longer cables to l.e.d. (light emitting diode) lights compared to halogen lights?
A. Yes. L.e.d.s consume a lot less power than incandescent lamps and are generally less sensitive to small voltage reductions, so cable runs can also be a lot longer. Note that l.e.d.s are vulnerable to overvoltage, so unless you are using an l.e.d. garden light like Barrel/Rebel spotlights, which are made especially to work from a wide range of both AC and DC voltages, you should generally use a regulated 12 volt DC power supply to ensure stable voltage to your l.e.d. deck lights, recessed uplights or steplights. See Help sheet 13 – Low voltage cabling layout for led garden lights and Help sheet 3 – l.e.d.
