This kind of lighting is really only for decorative purposes, since the output of the LEDs used is quite low. Solar powered candle lights require no wiring, so they’re very easy to install and require no maintenance. Of course, there is also none of the fire risk associated with real candles. As with all solar powered lights, it’s important to ensure they are installed in an area which will receive the maximum amount of sunlight possible during the day so the batteries recharge sufficiently to power the LED during throughout the night.
There are many different styles available, including ones mounted on posts which you can site in your garden or backyard; traditional lantern models designed to be fixed to a wall, hanging lights and free-standing pillar models.
Those manufactured from plastic may be less susceptible to weathering than some metal models at the cheaper end of the market. It’s also a good idea to make sure that your chosen lights are well sealed against the elements. There are reports of low cost models not providing a sound waterproof seal for the battery compartment, which can result in the contacts becoming corroded and the unit failing to work.
If you’re looking for a very pleasing, traditional candle effect for your decorative outdoor lighting project, then solar powered LED candle lights offer a reasonably priced option which is safe and maintenance-free.
