Buying an LED Table Lamp: A Guide to Brightness, Battery Life and Intended Use

An LED table lamp should take up little space, provide reliable illumination and suit its intended use. In practice, unclear information about brightness, battery life or ingress protection often leads to disappointing purchases. This is particularly true of cordless models, where it is worth looking closely at the technical specifications rather than relying on design promises alone.

Common pitfalls when buying LED table lamps

1. Battery life without a corresponding brightness rating

The stated runtime often applies only to the lowest brightness setting. For example, a battery-powered table lamp may stay lit for many hours, while its actual runtime at maximum light output is considerably shorter. You should therefore consider lumens, brightness level and operating time together.

2. Warm white light is confused with sufficient brightness

A table lamp with warm white light at around 2,700 to 3,000 Kelvin is ideal for creating a cosy atmosphere. However, concentrated work or detailed reading also require sufficient lumens and suitable light distribution. Warm white light alone says nothing about the actual brightness.

3. Outdoor suitability despite no IP rating

A portable or rechargeable table lamp is not automatically suitable for balconies and patios. The IP44 rating, for example, indicates protection against solid foreign objects measuring 1 mm or more and splashing water from various directions. A model rated IP20, on the other hand, is intended for dry indoor spaces and should not be used outdoors.

Technical specifications you should check

Brightness, colour temperature and dimming

Brightness is measured in lumens (lm). Low values may be sufficient for a decorative table light or night light. For reading or working, the lamp should direct the light precisely onto the area where it is needed. An LED reading lamp with a flexible arm or adjustable light head can be more practical than purely ambient lighting.

A dimmable table lamp allows you to adjust the light to suit the time of day and the activity. Also check whether only the brightness or the colour temperature can be adjusted. According to the product specifications, the Aigostar model covers a range of 2,700 to 6,500 Kelvin, providing warm, neutral and cooler light.

Power supply and charging connection

A cordless LED table lamp requires either an integrated battery, batteries or a solar module. With a rechargeable table lamp, the battery capacity, charging time, connection and included accessories are all relevant. A USB connection allows you to use the lamp with a laptop, power supply or power bank. Check whether a USB mains adapter is included: according to the specifications, the Aigostar model comes with the cable, but not the adapter.

For an outdoor solar table lamp, charging time, runtime, timer and IP rating are also important. The Katy lamp features IP44 protection, a lithium-ion battery, a stated charging time of 5 to 6 hours and a runtime of 6 hours.

Dimensions, stability and materials

Measure the available space before buying. Compact models, such as lamps measuring 20 to 30 cm in height, fit on bedside tables, shelves or small dining tables. Glass, metal and plastic differ in terms of weight, care requirements and susceptibility to impact. In a child's bedroom, the lamp should be placed securely and kept out of children's reach.

LED Table Lamp FAQ

How many lumens should an LED table lamp have for reading?

This depends on the distance, lamp design and light distribution. Lower lumen values are often sufficient for purely accent lighting. For reading, choose a model that directs the light onto the book or work surface. A dimming function makes it easier to adjust the brightness.

How long does the battery of a rechargeable table lamp last?

Runtime depends on battery capacity, brightness setting and operating mode. So do not compare only the maximum number of hours stated; also consider the charging time and brightness used. For longer periods of use, a USB table lamp with a power bank connection may be more practical.

Does an LED table lamp use a lot of electricity?

LED lights require comparatively little electrical power at a low wattage. The actual cost depends on wattage, daily usage time and the electricity price. With battery-powered and solar models, charging losses and the available sunlight also need to be taken into account.
