Dusk to Dawn Light Sensor – 10A | Adj LUX | 220V AC

Overview

The Dusk to Dawn Light Sensor (Model 1275) is a photocell light sensor switch operating on 220-240V AC mains supply, designed for automatic outdoor lighting control that switches lights on at dusk when ambient light falls below the set LUX threshold and switches them off at dawn when ambient light exceeds the set threshold — without any manual switching or timer programming. Rated at 10A with IP44 weatherproofing and a lux range of <5-50LUX Adjustable, the Model 1275 is designed for housing society compound and street light automation, housing colony gate and boundary light control, hotel driveway and garden light control, farmhouse outdoor flood light automation, commercial parking lot lighting control, and any Indian outdoor wired AC lighting environment requiring fully automatic dusk-to-dawn operation. The 5-50 LUX adjustable sensitivity allows the trigger threshold to be calibrated for different outdoor ambient light environments — urban areas with significant street lighting benefit from lower sensitivity settings while dark rural areas benefit from higher sensitivity settings.

LUX Threshold – <5-50LUX Adjustable

The Model 1275 lux level is <5-50LUX Adjustable — the confirmed threshold specification. The lux threshold controls the ambient light level at which the sensor triggers the connected load. The 5-50 LUX adjustable range enables the trigger sensitivity to be set precisely for the specific installation environment. For urban housing society compound lighting where residual artificial light from surrounding buildings maintains higher ambient levels at dusk, a lower sensitivity setting (5-10 LUX) ensures the sensor activates only when true darkness arrives. For rural farmhouse and estate outdoor lighting where true darkness falls more completely, a higher sensitivity setting (20-50 LUX) activates the connected load earlier at dusk.

Current Rating & Load – 10A | IP44

The Model 1275 is rated at 10A at 220-240V AC — the confirmed current specification from the product image. At 220V, the 10A rating accommodates a connected load capacity appropriate for standard outdoor lighting circuit loads. IP44 weatherproofing is confirmed, enabling permanent outdoor installation across India’s full climate range including monsoon rainfall, coastal humidity, and UV exposure. No time delay is specified in the product image for the dusk-to-dawn photocell models.

Auto Dusk-to-Dawn Operation – No Manual Switching

The Model 1275 operates fully automatically — no manual switching, timer programming, or daily adjustment is required after installation. The photocell detects ambient outdoor light continuously and switches the connected load on when darkness falls and off when daylight returns. For housing society compound lighting and housing colony gate lighting where the lights must activate each evening without manual operation by a security guard or resident, the automatic dusk-to-dawn function is the primary energy-saving and convenience benefit. No power cut re-setting or clock adjustment is required.

IP44 Weatherproofing – Outdoor Installation

IP44 confirms protection against solid particles larger than 1mm and water splashing from any direction — appropriate for permanent outdoor installation across Indian climate zones. The photocell sensor housing is designed for installation in outdoor light fittings, pole top positions, and wall mount positions exposed to Indian monsoon rainfall, coastal salt air, and UV radiation. For housing society compound street light poles and housing colony gate pillar light fittings, the IP44 photocell sensor installs directly on the light fitting without additional weatherproofing.

Installation – Series Wiring | Outdoor

The Dusk to Dawn Light Sensor Model 1275 wires in series with the connected outdoor light circuit. The photocell housing is positioned outdoors facing upward or skyward to measure ambient light without being shaded by structures. Mains AC 220-240V connects to the sensor input, and the switched output connects to the outdoor LED load rated within the 10A current capacity. IP44 weatherproofing enables outdoor installation in all Indian climate conditions including monsoon rainfall. For housing society compound lighting schemes where multiple outdoor lights on the same circuit are to be automated together, a single Model 1275 sensor controls the entire circuit output from one installation position. No programming, timer setting, or manual adjustment is required after installation — the sensor operates automatically each dusk and dawn.
