The LED floodlight is the most pragmatic lamp around the house: its job is to light the driveway, the gate, the yard or the façade – brightly, cheaply and reliably, for years and in any weather. The trouble is that you buy one about once a decade, while manufacturers speak the language of watts, lumens, beam angles and IP codes. This guide translates it all, step by step: how a floodlight differs from a spotlight and the old “halogen”, how much power a driveway needs versus the pitch behind the barn, how a motion sensor works and where not to point it, which colour temperature keeps the yard from looking like a supermarket car park – and how many floodlights a typical plot really needs.
