The best radar motion sensor bulb for an Indian bathroom in 2026 is the Esysense 7W B22 Auto On/Off — plugs into any standard B22 bayonet fitting, activates the moment you walk in, and auto-switches off after the delay. For kitchens, the 10W B22 delivers better brightness for a full kitchen work area. All Esysense sensor bulbs use radar (microwave) detection — unaffected by Indian summer temperatures that degrade PIR sensors. No app, no Wi-Fi, no setup. Screw in and leave the wall switch permanently ON.

Frequently Asked Questions

Q: Can I use the 7W B22 in a windowless bathroom?

A: Yes — use the standard Auto On/Off model (the 7W B22). The Day/Night models are not suitable for windowless bathrooms as the LDR sensor keeps the bulb off during daytime regardless of motion.

Q: How long does the bulb stay on after I leave the bathroom?

A: The delay period is approximately 60 seconds — verified on Esysense product pages. After no motion is detected for this period, the bulb switches off automatically.

Q: Does kitchen steam or cooking smoke affect the sensor?

A: No — radar (microwave) detection is completely unaffected by steam, smoke, or cooking heat. The sensor detects movement via reflected microwave signals, not heat or optical clarity.

Q: Do I need one bulb per room or can one cover both bathroom and kitchen?

A: One bulb per room — each unit is a self-contained sensor and LED. Each manages its own detection zone independently. Install one per fitting in each room you want automated.

People Also Ask

Q: What is the cheapest motion sensor bulb in India?

A: The Esysense 7W B22 Radar Motion Sensor Bulb — verified from esysense.com in 2026. One of the lowest prices for a radar-based sensor bulb from a verified Indian brand. Check current pricing at esysense.com/products/motion-sensor-bulb-auto-on-off-day-night-7w

Q: How does a radar motion sensor bulb work in a kitchen?

A: The bulb emits low-power microwave signals continuously. When you enter and move in the kitchen, the reflected signal pattern changes — the Doppler shift triggers the LED to activate. Steam, smoke, and cooking heat are irrelevant to radar detection. When the kitchen is empty for the delay period, the bulb switches off.

Q: Is a 7W motion sensor bulb enough for a bathroom?

A: For standard Indian attached bathrooms up to approximately 6 sqm: yes — 7W provides adequate brightness for all bathroom activities at standard 2.7-3m ceiling height. For larger master bathrooms, step up to the 10W model for better coverage.

Conclusion

For bathrooms: the 7W B22 Auto On/Off is the correct starting choice — standard fitting, adequate brightness, fastest payback. For kitchens: the 10W B22 in Cool White. Both use radar sensing for reliable Indian year-round performance. Verify current stock and pricing at esysense.com/collections/motion-sensor-bulbs before ordering.
