Part of the ' Solar 365' range from Smart Solar, these intelligent solar post lights are designed to self adjust their own brightness when they are low on charge. Most solar lights automatically switch on at full brightness, but in winter time or prolonged periods of cloudy weather that can mean your lights don't come on at all, or only light for a few minutes. These lights however still light up all year, albeit a little dimmer if it hasn't had enough sunshine. The posts are made from grey plastic to look like industrial grey metal, & the styling of the posts is very similar to the industrial caged bulkhead lights or maybe nautical style lights. & the bulb although modern LED, is made to look like an old style Edison filament bulb.
