This is true of packaged systems offered by major retailes and solar lighting. The fixtures used by Landscape Lighting by Ron are commercial quality and are an excellewnt light source. The uplights use a MR16 halogen light bulb which is very energy efficient. The bulbs are available in 20, 35 and 50 watts. Selecting the proper bulb assures adaquate light. A 50 watt MR16 bulb will cast good light higher than a three story home.
Halogen bulbs provide a pure white light so there is true color rendition. The greens are green and the whites are white.
