Best motion sensor dusk-to-dawn outdoor security flood lights

Top pick: GE Outdoor Security Floodlights (2,500 lumens, IP65) — the closest thing to your 2,000-lumen target that still has both a motion sensor and dusk-to-dawn operation. IP65 sealing means it shrugs off rain and snow, and GE's motion head covers a wide 240° sweep out to about 40 feet, so it catches someone walking up rather than only head-on.

Who the others suit:

• Philips 44W two-head flood — if you want more punch and a wider spread over a driveway or side yard; it keeps PIR motion plus dusk-to-dawn and four modes.
• SANSI 55W — for a bright, simple motion-triggered light where you don't need the photocell.
• GE Outdoor Security Area Light — for constant dusk-to-dawn coverage of a yard or parking pad, no motion switching.
• PURICH LED — a budget option for very bright motion-only coverage.

Note that most of these run brighter than 2,000 lumens; if you want to stay near that output, the GE flood is the one to start with.
