They are fast and easy to install since you don't have to worry about first installing the light bulbs or constantly changing them when they go out. Low Voltage RGBW Landscape Lights with integrated light bulbs can be much brighter than normal light bulbs due to the LED chips being able to hold more wattage than a normal bulb.
