A cordless lamp provides illumination without being tethered to a power outlet. This flexibility comes from an integrated, rechargeable battery. These lamps are suitable for a wide range of applications, from focused task lighting at a workstation to creating ambient light in living spaces and outdoor areas. Choosing the right model requires an analysis of its technical specifications and functional features.
The decision to purchase a cordless lamp should be based on objective criteria. The following technical parameters are relevant for your evaluation:
The battery's capacity, measured in milliampere-hours (mAh), is a key indicator of its potential runtime. A higher mAh rating generally correlates with longer operation. However, the actual runtime is directly dependent on the selected brightness level. Manufacturer claims about maximum runtime usually refer to the lowest dimming setting. The charging time, often facilitated via a USB port, is also a relevant factor for everyday convenience.
Modern cordless lamps almost exclusively use LED technology, which is both energy-efficient and long-lasting. Key metrics include:
The materials used affect both the feel and the durability of the lamp. Common materials include plastics, metals like aluminium or brass, and glass. For outdoor use, the IP rating is crucial. An IP44 rating, for example, certifies protection against splashing water from all directions, making it sufficient for use on a balcony or patio.
The form factor determines the primary use case. A cordless table lamp serves as a decorative or functional element on tables and sideboards. A cordless reading lamp, often designed as a clip-on light, provides precise, focused illumination. A portable lamp with a handle is designed for on-the-go use, while a cordless bedside lamp offers a clean, flexible solution for the bedroom.
The following models have been selected based on their technical specifications and functional design.

1. How long does the battery of a cordless lamp last? The battery life depends on the battery capacity (mAh) and the selected brightness level. Compact reading lamps often provide 5–10 hours of runtime, while larger, high-capacity table lamps can last for 80, 100, or even more hours on the lowest brightness setting. Manufacturer specifications for runtime typically refer to the lowest brightness level.
2. What does the IP44 rating on a lamp mean? IP44 is an Ingress Protection rating. The first digit (4) indicates that the enclosure is protected against solid foreign objects with a diameter of ≥ 1.0 mm. The second digit (4) signifies that the lamp is protected against splashing water from any direction. A lamp with an IP44 rating is therefore suitable for use in sheltered outdoor areas like balconies or patios, as well as in humid indoor environments.
3. Can you use a cordless lamp while it is charging? Most modern cordless lamps can be used while charging. However, this depends on the specific model and its electronics. Check the product description or the manufacturer's manual for definitive information.
