Buy LED Lighting: A Practical Guide to Night Lights, Cupboard Lights and More

LED lighting can save electricity in the home, make walkways safer and provide targeted illumination for work surfaces. The range extends from simple LED night lights and sensor lights to LED cupboard lighting and LED TV backlighting. However, the sheer variety of products can make comparison difficult.

Three typical purchasing decisions often lead to unnecessary expense:

  • Unclear sensor specifications: Some lights do not respond to movement, but only to the brightness of their surroundings. A night light with a twilight sensor is therefore not automatically a motion-sensor light.
  • Unsuitable light colour: Cool white light can be useful for work surfaces, but may feel less comfortable in a bedroom or hallway. Warm white LED lighting usually falls within a range of around 2,700 to 3,300 Kelvin.
  • Insufficient protection for the intended location: A light designed for indoor use should not be installed on a balcony, by an entrance or in a garage. For outdoor areas, the specific IP rating, installation instructions and suitability for damp conditions are all crucial.

Technical specifications to check before buying

1. Lumens, Kelvin and colour rendering

Brightness is measured in lumens (lm), not watts. Watts primarily describe power consumption. 40 lumens may be sufficient for an orientation light in a hallway, while a task light may require considerably more illumination.

Colour temperature is specified in Kelvin (K):

  • Warm white: around 2,700–3,300 K, suitable for living rooms and bedrooms
  • Neutral white: around 4,000–5,000 K, suitable for kitchens, hallways or workspaces
  • Cool white or daylight white: from around 6,000 K, often used for functional lighting

A CRI or Ra value of 80 or above indicates how naturally colours appear under the light. This value does not replace personal assessment, but it does allow for a more objective comparison.

2. Sensor type, range and power supply

A twilight sensor measures the brightness of the surrounding area. According to the product specifications, the Aigostar LED Night Light switches on when the brightness falls below 20 lux and switches off again when sufficient light is available. A PIR sensor, by contrast, detects movement. The 20 cm cupboard light is specified as having a detection range of 3 to 5 metres.

You should also check whether the light:

  • plugs directly into a socket,
  • needs to be charged via USB,
  • requires batteries, or
  • remains permanently connected to a power adapter.

A wireless LED lamp can be installed flexibly, but needs to be charged regularly. With socket-powered models, this maintenance step is not required.

3. Dimensions, installation and IP rating

Measure the available space before buying. For cupboards and shelving, length, depth and installation clearance are important. Adhesive strips are suitable for smooth, clean surfaces; on uneven surfaces, mechanical fastening may be more reliable.

The IP rating is relevant for damp rooms and outdoor areas. IP20, as used for the Aigostar Night Light, indicates use in dry indoor spaces. An outdoor wall light with a motion sensor should only be used if the stated IP rating and installation instructions cover the intended location. The product description for the Pheashine U-shaped outdoor wall light refers to a weather-resistant construction; the specific IP rating should be checked against the listing and packaging before installation.

Comparing other useful applications

For a child's bedroom, a star projector such as the Nomader VIVREAL can combine decorative light projection with a speaker function. Before buying, check the volume, timer, power supply and whether it can be placed safely out of the reach of young children.

For outdoor areas, the installation location, connection and IP rating are key considerations. According to the product description, a Pheashine outdoor wall light with 24 watts, light and motion sensors and 3,000 Kelvin is intended for paths, entrances and patios. Outdoor electrical lights should be installed according to the instructions; if you are unsure, consult a qualified electrician.

FAQ: Frequently asked questions about LED lighting

How much electricity does LED lighting use?

Consumption depends on the wattage and how long the light is used each day. A 1-watt light used for ten hours theoretically consumes 0.01 kilowatt-hours. To calculate the running cost, multiply this figure by your electricity tariff. Sensor and twilight functions can reduce operating time compared with lights that remain switched on continuously.

How long does an LED lamp last?

The manufacturer specifies the lifespan in operating hours. The Aigostar LED Night Light mentioned above is rated for 25,000 hours. This is a product specification and depends, among other things, on temperature, the power adapter, switching cycles and operating conditions. Good ventilation and a suitable power supply help ensure proper operation.

Which LED lighting is suitable for a hallway at night?

For simple orientation, a dimmed LED night light with a twilight sensor is often sufficient. If you want the light to come on only when someone enters the hallway, a sensor light with PIR motion detection is more suitable. Make sure it is positioned to avoid glare, provides enough brightness for steps and, where children are concerned, is installed securely and left uncovered.
