Solar lighting is the safest and easiest kind of outdoor lighting to install. Each light fixture contains a scientifically design solar collector panel that converts daytime-sunlight into electrical energy. This energy is stored in highly efficient rechargeable batteries, used to light the fixture at night. Each solar light operates independently from others without the need for of a transformer and wiring. This makes solar lighting especially suitable for use in remote areas and locations near water. Our Solar lights utilize the latest LED technology and provide sufficient light to mark entrances, accent walkways & steps and to indicate the location of darkened obstacles at night. Solar lights are not for every lighting application. Malibu Solar Lights produce a glow that is ideal for outlining locations and darkened areas such as steps, walks, etc. Be sure all solar collector panels are installed in a sunny location where they will receive adequate, unobstructed sunlight each day. Solar light performance will be diminished during cloudy, rainy, or wintery weather conditions.  These solar lights for example, are not powerful enough to illuminate a flag pole throughout the evening. Be sure to install the solar collector panel where it will receive adequate, unobstructed sunlight each day.  Solar light performance will be diminished during cloudy, rainy or wintery weather conditions. With fully charged batteries, solar lights will provide many hours of nighttime illumination. Like anything running off a battery, you may need to replace the batteries to these  units from time to time. Recently, the market has been flooded with cheap solar garden lights, these imported lights can easily be categorized as junk. We tested the Intermatic line of solar lights. We have found these lights to be of a very good quality, and design, especially the lights constructed of metal. Some of the original lights we tested back in 2002, are still in operation today, four years later.
