We exclusively use low voltage lighting systems. Here is why:

LOW VOLTAGE (12 volt) ADVANTAGES

• Flexible fixture positioning allows easy movement as
  landscape matures.

• No need to bury fixture or supply cable.

• Small, concealable fixtures are easy to hid within
  the landscape.

• Safe around water features.

• Less Potential of damaging root systems.

• Pinpoint accuracy of light sources.

• Energy efficient  -  more light per watt.

DISADVANTAGES

• More expensive initial costs for material - transformer
  needed.

LINE VOLTAGE (120 volt) ADVANTAGES

• Low initial material cost.

• Inexpensive lamps.

• Can access more power.

DISADVANTAGES

• High operational costs over time.

• Must trench and distribute wire in conduit 18: below
  ground for protection.

• Expensive to move or relocate fixtures as landscape
  matures.

• Need a junction box for each fixture.

• More glare is produced due to lamp construction.

• Less controllable light.
