Most farms have outlying barns and sheds where there’s no mains power. That’s no problem in the daytime, but no fun if you have to rely on a torch after dark.

However, Berkshire firm Bright Spark Solar reckons it has the answer with its latest 44-LED solar-powered floodlight.

The lithium-ion battery is fully charged after nine hours of bright sunlight, it says, which then gives five nights of light from the low-wattage LED floodlight.

Two screws secure the solar panel bracket and another two screws let you fit the floodlight to a wall. 

A PIR motion sensor detects movement up to 5m away and across a 120deg field.

This triggers the floodlight to come on with the full 1,000 lumens, equivalent to a 120W light bulb, but returns to a light-saving mode of 100 lumens when activity is no longer detected after 30sec. 

A 3.5m cable allows the solar panel to be mounted some way from the LED floodlight.

Made from aluminium alloy with a toughened glass lens, the LED floodlight is weatherproof to IP65 and measures 24x12x9cm, with the solar panel measuring just 27x18x2cm.

It costs £66 plus VAT.
