Frequently Asked Questions

Q: Can I use two motion sensor bulbs in a long corridor?

A: Yes — for corridors over 5 meters, install two bulbs at equal intervals. Each covers its own detection zone, ensuring the full length is illuminated as you walk through.

Q: Will a motion sensor bulb for a balcony stay on all night?

A: No — a Day/Night radar bulb activates only after sunset when motion is detected and switches off after the preset delay. It does not stay on all night.

Q: Is a motion sensor bulb safe for a bathroom?

A: Yes — motion sensor bulbs are standard LED products. For bathrooms, choose a model rated IP20 or higher. All Esysense radar bulbs operate on the same safe low-voltage LED technology as standard bulbs.
