Esysense T5 motion sensor tubelights at esysense.com: the 18W Radar Motion Sensor Tubelight and the 20W Motion Sensor Tubelight. Both use radar (microwave) detection and are Auto On/Off. The 18W is the right choice for standard Indian home hallways up to 4 meters. The 20W is better for longer hallways, office corridors, and any space with slightly higher ceilings. Both are T5 format — not T8. If you have existing T8 fittings, T5 tubes will not physically fit.
Both products below are verified from esysense.com/collections/motion-sensor-tubelight.

T5 vs T8 — What Is the Difference?
The number in T5 and T8 refers to tube diameter in eighths of an inch. This affects the physical holder and pin configuration — the two formats are not interchangeable.
1. T5 Tube
(i) Diameter: 16mm (slim, modern profile)
(ii) Common Use in India: Modern residential and new commercial installations
(iii) Holder Availability: Readily available from electrical suppliers
(iv) Physical Compatibility: Fits only T5 holders
2. T8 Tube
(i) Diameter: 26mm (standard Indian commercial fitting)
(ii) Common Use in India: Older commercial buildings, institutions, and factories
(iii) Holder Availability: Very widely available across India
(iv) Physical Compatibility: Fits only T8 holders
Bottom line:
If your existing fittings are T5: the Esysense T5 sensor tubelights are direct replacements. If your fittings are T8: check esysense.com, or use motion sensor panel lights as an alternative ceiling solution.
Motion Sensor Tubelight for Hallway — Why Tubelights Work Best
Hallways are the ideal application for motion sensor tubelights — and the linear T5 format is specifically well-suited to the space:
Brief frequent use: someone passes through, needing light for 30-90 seconds, then nobody's there for 20-30 minutes. Motion sensing eliminates all unnecessary illumination automatically.
Forgotten light problem: hallway lights are among the most frequently forgotten lights in Indian homes — left on from morning until everyone is in bed. Auto on/off eliminates this entirely.
Linear coverage: a single T5 tube provides even illumination along the full hallway length from a single ceiling fitting — more coverage per fitting than a point-source bulb.
Radar advantage for hallways: ceiling fans in adjacent rooms, temperature variations near AC vents, and Indian summer heat all degrade PIR sensor reliability. Radar is unaffected by all three.
1. Standard Indian Home Hallway
(i) Recommended Product: 18W T5 Radar Motion Sensor Tubelight
(ii) Why: Provides sufficient brightness for hallways up to approximately 4m long.
2. Long Home Hallway or Approach Corridor
(i) Recommended Product: 20W T5 Motion Sensor Tubelight
(ii) Why: Additional wattage helps maintain uniform illumination over longer distances.
3. Apartment Staircase Landing
(i) Recommended Product: 18W T5 Radar Motion Sensor Tubelight
(ii) Why: Ideal for compact landing areas with automatic activation.
4. Office Corridor
(i) Recommended Product: 20W T5 Motion Sensor Tubelight
(ii) Why: Better light spread across wider commercial corridors.
5. Small Lobby or Common Area Landing
(i) Recommended Product: 18W T5 Radar Motion Sensor Tubelight
(ii) Why: Adequate coverage for compact common spaces.
Bottom line:
18W vs 20W: the price difference is minimal — negligible. If your hallway is longer than 4 meters or you are unsure, choose the 20W. For standard Indian home hallways under 4 meters, the 18W is sufficient, making it an exceptional value.
Motion Sensor Tubelight for Hall — Indian Drawing Rooms, Dining Areas, Lobbies
In Indian usage, 'hall' covers several distinct spaces — residential drawing rooms and dining areas, apartment common area lobbies, office reception halls, and community gathering spaces. Each has specific considerations:
1. Residential Drawing Room
(i) Product: 20W T5 Motion Sensor Tubelight
(ii) Recommendation: Suitable for daily general lighting.
(iii) Consideration: For TV viewing or prolonged sitting, add a presence sensor or secondary lighting circuit to avoid unintended switch-off.
2. Home Dining Area
(i) Product: 20W T5 Motion Sensor Tubelight
(ii) Recommendation: One tube typically covers a standard dining area.
(iii) Consideration: Set delay time to 8–10 minutes to prevent lights turning off during meals.
3. Apartment Common Area Lobby
(i) Product: 18W T5 Radar Motion Sensor Tubelight
(ii) Recommendation: Reliable automatic entry/exit lighting.
(iii) Consideration: Radar sensing performs better near entrance doors and changing outdoor temperatures.
4. Office Corridor (Multiple Sections)
(i) Product: 20W T5 Motion Sensor Tubelight
(ii) Recommendation: Install one unit per corridor section.
(iii) Consideration: For corridors longer than 8m, place one tube every 4–5m with overlapping detection zones.
5. Community Hall
(i) Product: Multiple 20W T5 Tubelights + Microwave Zone Sensor
(ii) Recommendation: Ideal for large spaces with intermittent occupancy.
(iii) Consideration: Centralized sensor control prevents lights from operating unnecessarily during vacant periods.
Bottom line:
For a residential drawing room or dining area: set the tubelight delay to 8-10 minutes so seated occupants are not disrupted during meals or TV time. For corridors used only as passthrough: 1-2 minutes delay is sufficient and maximizes electricity saving.
Why Radar Sensing Is Essential for Indian Hallways
(i) Wide detection without positioning: radar from a ceiling-mounted tube detects movement across a broad zone below — no need to walk in a specific direction or position yourself under the sensor. Entering from a side door or moving slowly with bags is reliably detected.
(ii) Ceiling fan immunity: many Indian home hallways have ceiling fans. PIR sensors can false-trigger from fan motor heat and airflow-driven temperature variations near the fan. Radar is completely unaffected by fan operation.
(iii) Indian summer reliability: at ambient temperatures above 35-38 degrees C (common in most Indian states from April to September), PIR sensors lose sensitivity. Radar performance is identical at 15 degrees C and 45 degrees C.
(iv) Detection range: up to 9 meters as listed on Esysense product pages — more than sufficient for any standard Indian home hallway from a single ceiling-mounted tube.
Installation Guide — T5 Motion Sensor Tubelight
Retrofitting into an existing T5 fluorescent fitting:
1. Isolate the circuit at the MCB. Verify power is off with a non-contact voltage tester.
2. Remove the existing T5 fluorescent
