Which control fits your lighting setup?
Most outdoor circuits need dusk-to-dawn switching. Motion sensors and timers solve more specific problems.
Use one day/night sensor at the circuit board; add a contactor for heavy LED loads.
Use PIR motion sensors locally so each landing or passage responds to movement.
Use day/night sensor plus timer when lights should start at dusk and shut later.
Use 50W or 75W panels as replacement panels when the old panel is damaged or undersized.
How to Choose a Sensor or Timer for Your Lights
Every device here closes a circuit so lights switch automatically. The difference is what tells it to switch: fading daylight, human movement or the clock.
Choose the right trigger
Use a day/night sensor when lights should follow sunset, a motion sensor when a person should trigger the light, and a timer when the schedule is fixed. For most outdoor lighting circuits, dusk-to-dawn is the default.
Day/night sensor is the outdoor default
Use it for street lights, society roads, gardens, gate lights, facade lighting, farmhouse driveways, warehouse yards and temple exteriors. Mount it away from the lamp it controls so the light does not cycle on and off.
Motion sensors are local
Use PIR sensors for staircases, corridors, lobbies, bathrooms, basements, stilt parking, porches and service areas. Wall sensors work best around 6-8 ft and aimed across the walking direction.
Timers are for schedules
Use digital timers for shop signage, hoardings, pumps, decorative lighting and factory circuits that must shut at a set hour. For general outdoor lights, pair a timer with a day/night sensor rather than replacing the sensor.
Check load before ordering
LED drivers draw a high inrush current at switch-on. As a practical rule, load a sensor to no more than about half its rated capacity for LED circuits. Above roughly 1,500W, use the sensor to switch a contactor.
One sensor can control a circuit
A single day/night sensor can control an entire lighting circuit. You do not need one photocell per pole. Motion sensors are different because each one must physically see the person.
Solar panels for street lights
50W and 75W panels are useful as replacement panels for semi-integrated solar street lights, or for small off-grid DC setups. Match voltage first, then choose wattage for charging speed and cloudy-weather recovery.
Sensors & Timers FAQ
Quick answers before choosing the right automatic switch.
Use a day/night sensor, also called a photocell or dusk-to-dawn switch. It reads ambient light and turns the circuit on at sunset and off at sunrise automatically.
One sensor controls an entire circuit, not a single light. The limit is electrical load. For LED loads, keep the sensor to about half its rated capacity, or use a contactor for larger circuits.
No. One day/night sensor wired into the supply feeding the poles can control all of them. Motion sensors are the exception because each sensor needs to see movement locally.
A motion sensor reacts to people moving. A day/night sensor reacts to ambient light and stays on through the night. Use motion for stairs and entries; use day/night for outdoor area lighting.
The day/night sensor is probably seeing the light it controls. Reposition or shield the sensor so it faces away from the fixture.
Yes. Wire them in series: the day/night sensor turns lights on at dusk, and the timer shuts them at a fixed hour.
Outdoor models are IP44 or IP65 depending on the product. Use outdoor-rated sensors in rain-exposed or semi-exposed areas such as stilt parking and open corridors.
50W and 75W are common replacement sizes for 12W to 30W semi-integrated solar street lights. Match the panel voltage to the light controller before choosing wattage.
