The Ideal Lux Diesis 291109 is a contemporary LED table lamp in a satin brass finish, designed to provide focused, adjustable light for desks, reading areas and side tables. Its slim metal structure supports a compact directional diffuser that can be rotated and inclined, making it practical where you want to aim the light rather than illuminate an entire room evenly. The integrated warm white LED combines a focused beam with high colour rendering, while an onboard dimmer gives greater control over brightness. At approximately 65.5 cm high and 43 cm deep, the Diesis has a noticeable architectural presence without requiring the floor space of a larger reading lamp.
The Diesis has a clean, modern profile with a metal frame finished in satin brass. Its slender upright support and projecting arm lead to a compact cylindrical diffuser, creating a purposeful task-light appearance that works particularly well with contemporary interiors.
The diffuser is adjustable in both rotation and inclination, so its angle can be changed to suit the position of the lamp and the area being illuminated. A circular base provides a simple visual anchor, while the coordinated brass finish gives the fitting a consistent decorative look.
This table lamp uses an integrated 6.5W LED module, so no separate bulb is required. It produces warm white light at 3000K with a useful light output of 390 lumens and a CRI above 90, helping colours and surface details appear natural under the light.
The 30-degree beam is relatively focused, making the Diesis particularly suitable for reading, desk work or highlighting a smaller area. Its adjustable diffuser lets you redirect the beam as required instead of relying on a fixed light position.
An onboard dimmer is included, providing brightness adjustment directly from the lamp. The integrated LED source is not replaceable, while the separate electronic power supply is included and is specified as replaceable.

Understanding LED colour temperature and the Kelvin scale
Colour temperature 2000K to 3000K, the light produced is often referred to as a "warm white", "soft white", occasionally called a "candle white". It ranges from orange-ish to yellow-ish white in appearance. This kind of light is attractive, enjoyable, comfortable and relaxing.
Colour temperature 3100K to 4500K, the light produced is often referred to as a "neutral white", "bright white" or "natural white". Light sources within this range will emit a more neutral white light and may even have a slightly blue tint. This kind of light is bright, vibrant and clean appearing.

Colour temperature 4600K and above, the light produced is often referred to as a "cool white", "pure white" or "day white". Light sources in this range will have a blue-ish white tint to them. The higher the number, the more blueish it will appear. This kind of light will appear crisp, invigorating and energetic.
