These 3 floodlights attach to a seperate solar panel (included) so has more capacity to hold a charge and to utilize brighter bulbs producing more light.
You can illuminate large areas of your garden or use them for uplighting signs, statues, trees, shrubs, walls and fences.
Solar powered means there is no connection to your electrical system so there is nothing being added to your light bill.
No need for an electrician. You can connect these yourself if you have even the slightest skill set.
