How many lumens do I need for an outdoor floodlight?

For general security floods covering a driveway or backyard, reviewers across mainstream tech press and specialist communities generally point to 2,000–7,000 lumens as the sweet spot. Wall-mounted dusk-to-dawn fixtures in the 4,000–7,500 lumen range (like the LUTEC 72W or Onforu 75W) cover a typical residential lot. Stadium-grade 50,000+ lumen units are overkill for a home and can create glare complaints from neighbors.
