Lamp holder with twilight sensor and timer MACLEAN MCE21W E27 100W white

MACLEAN MCE21W is a lamp holder designed for E27 bulbs up to 100W, integrating a twilight (dusk-to-dawn) sensor and an adjustable timer in a compact white enclosure. The device detects ambient light and automatically switches the connected lamp on at low light levels and off at daylight. The timer function allows setting a delayed switch-off after illumination, enabling scheduled lighting without additional control hardware.

Advantages

The combined twilight sensor and timer provide autonomous operation, reducing the need for manual switching and helping to lower energy consumption. Its compatibility with standard E27 bulbs ensures wide lamp choice, while the simple white design suits various exterior and utility settings. Installation requires no complex wiring beyond a standard lamp holder connection, and the timer offers flexibility for dusk-triggered or scheduled lighting cycles.

Suitable for

• Outdoor porches and entrances
• Corridors, stairwells and common areas
• Garages, utility rooms and sheds
• Security and pathway lighting with dusk-to-dawn operation

Key specifications

• Bulb base type: E27
• Maximum lamp power: 100 W
• Built-in twilight sensor for automatic light detection
• Adjustable timer function for delayed switch-off
• Colour / finish: white
• Suitable for indoor and sheltered outdoor use (check local installation norms)

How to use

Install the lamp holder in place of a conventional E27 socket following local electrical safety standards and with power switched off. Screw a compatible E27 lamp into the holder, restore power, and allow the twilight sensor to calibrate to ambient light conditions. Use the timer control to set the desired delay after activation; when ambient light falls below the sensor threshold the lamp will switch on automatically and will switch off according to the timer setting or when ambient light rises above the threshold.

Usage recommendations

For reliable operation, position the lamp holder where the sensor is not directly exposed to other artificial light sources that could prevent correct dusk detection. Use bulbs within the specified wattage and appropriate for the intended environment. Periodically check mounting and electrical connections and follow local codes for outdoor installations.
