Outdoor lighting control

Day-night sensors: automatic outdoor lighting without guesswork

A day-night sensor switches a connected light on when the surrounding light level falls and off again when daylight returns. Use this guide to choose between a separate sensor, a fitting with built-in control, or a solar light that manages its own evening schedule.

Start with the job

Which setup fits your lighting problem?

The right route depends on whether you are adding control to an existing light, replacing the fitting itself, or lighting a place where running a cable is impractical. Check the product specification and electrical load before purchase.

Patrol V2 50W LED floodlight with day-night sensor

01 / BUILT-IN CONTROL

Replace the floodlight

Patrol V2 combines a 50W LED floodlight with a built-in day-night sensor and 3CCT selection. It is a useful starting point for a driveway, entrance or boundary area, subject to the listed IP65 specification and the actual mounting position.

02 / SEPARATE CONTROL

Keep the existing light

The Red Day/Night Switch is the separate-control route for a suitable existing lighting circuit. Its listed 10A rating still needs to be matched to the connected load, and mains wiring should be completed by a qualified electrician.

03 / SOLAR INSTALLATION

Avoid a new supply cable

The 1.5W Outdoor Solar LED Sensor Wall Light suits a smaller outdoor wall location where a mains connection is not the right starting point. Check the panel's daylight exposure, mounting position and product instructions before choosing it.

Before the electrician arrives

Five checks that prevent a frustrating install

Load

Match the sensor rating to the light or lights it will control.

Position

Choose a place where the sensor can read changing daylight without being shaded by the fitting.

Environment

Use the product's stated IP and installation guidance for the actual outdoor exposure.

Switching

Decide whether you need dusk-to-dawn operation, motion activation or a manual override.

Access

Allow for safe wiring, maintenance and a clear route to the panel or fitting.

Mains installation should be handled by a qualified electrician. A sensor does not correct an unsuitable fitting, overloaded circuit or poorly placed light.

Common questions

Day-night sensor questions worth settling first

Is a day-night sensor the same as a motion sensor?

No. A day-night sensor responds to surrounding light levels. A motion sensor responds to movement. If you need the light to stay on through the night, check the product control type before buying.

Can a separate switch control any outdoor light?

Not automatically. Check the listed load, supply arrangement, environment and fitting suitability. Ask a qualified electrician to confirm the circuit before installation.

Where should a solar sensor light go?

Choose a position where the panel receives useful daylight and the light covers the intended wall or path. The product instructions remain the final guide for installation.
