Strengths and limits

• Sensor inside the bulb — no extra wiring for cellar, hall or stairs.
• Radar sees through closed globes where PIR fails.
• Public datasheets and long commercial warranties (3–5 years on many lamp families).
• 3 m range only — not for a long hallway; 4000 K is harsh for living rooms; 30 s off delay fixed.

Warranty (LEDVANCE FR pages, 23/10/2026)

LED Classic Energy A/B/C up to 5 years; many STAR families 3 years; luminaires 3–10 years depending on range. Star A75 Motion family: rely on minimum 2-year seller conformity if not listed explicitly.
