I also got another low voltage quote for about 3700 so this is the going rate these days I guess.
Line voltage vs low voltage landscape lighting. Line Voltage Vs. Because low voltage DC is more likely to have losses and voltage drops and the longer the wires are the more voltage drop will be there. Line-voltage LEDs are operated with 120V mains voltage.
Must be buried 18 inches underground. It is standard in lighting while low voltage 12v or 24v lighting is used less commonly. This ensures powerful and even light output from each fixture without degrading lamp life.
Low Voltage Landscape Lighting Factors. Historically the voltage drop on a long run of lights has been an argument for using line voltage. Low voltage wires can be buried 6 underground with or without conduit and the fixtures can easily be pulled up and moved around to.
The most common type used in residential applications is low voltage but there are many commercial systems that also utilize low voltage. For the current system almost all of us know that low voltage is safer. Most landscape lighting is 12 volt or low voltage which is much safer and more flexible to install.
Line voltage outdoor lighting fixtures tend to be very big and output a lot of light. The goal when designing a low voltage landscape lighting system is to have the voltage at each fixture between 108 volts and 118 volts. A low voltage light will have a cable like a lamp or a hairdryer.
When utilizing a higher-voltage tap at the transformer the voltage starts out high then drops down to the proper voltage. And need weather-tight junction boxes. Line voltage lighting has a thicker cable than low voltage lighting.
