The Ideal Lux Diesis 279800 is a slim black LED floor lamp designed to provide focused light beside a sofa, armchair, desk or reading area. Its understated metal structure and compact adjustable diffuser give it a clean, contemporary appearance without taking up much visual space. The included 4.5W LED light source produces 390 lumens of warm white 3000K light, making the lamp particularly useful where directed supplementary lighting is preferred to broad room illumination. At approximately 151 cm high, the Diesis works well alongside seating, while the diffuser can be rotated and inclined to direct the light towards the required area. A switch on the PVC power cable provides convenient everyday on/off control.
The Diesis has a minimalist profile built around a slender metal stem, circular base and compact directional diffuser. Product code 279800 is finished in black, creating a simple contemporary look that is easy to coordinate with modern living spaces, bedrooms and home offices.
The diffuser is deliberately small in relation to the height of the lamp, helping the fitting remain visually unobtrusive beside furniture. Its metal construction and restrained shape place the emphasis on practical directional lighting rather than decorative bulk.
The lamp is supplied with a 4.5W LED light source producing 390 lumens at a warm white colour temperature of 3000K. This directed output is particularly suitable for supplementary lighting beside a chair, sofa or work area rather than acting as the sole general light source for a large room.
The diffuser can be rotated and inclined, so the direction of the light can be adjusted to suit the seating position or task. A switch is fitted to the PVC power cable for straightforward on/off operation. Dimmability is not confirmed by the current manufacturer information, so the lamp should not be described as having adjustable brightness.
The current Ideal Lux catalogue describes the LED light source as replaceable. The light source is included with the lamp.

Is the LED light source included?
Yes. The Diesis 279800 is supplied with its LED light source, so there is no separate bulb to purchase. Current Ideal Lux information specifies a 4.5W LED source producing 390 lumens at 3000K.
Can the direction of the light be adjusted?
Yes. The compact diffuser can be both rotated and inclined. This makes it easier to aim the light towards a book, chair, desk or another specific area rather than leaving the beam in one fixed position.
Is the Ideal Lux Diesis 279800 dimmable?
Dimmability is not confirmed in the current manufacturer specification. The lamp has a switch on its power cable for on/off operation, but it should not be assumed to offer brightness adjustment.
Is this floor lamp suitable for reading?
Yes. Its adjustable diffuser and directed light make it particularly suitable beside a sofa, armchair or reading chair. The 390 lumen output is intended as focused supplementary illumination rather than powerful general lighting for an entire room.
Can this lamp be used in a bathroom or outdoors?
No. The Diesis has an IP20 rating and is intended for dry indoor locations. It should not be used outdoors or in bathroom zones that require increased protection against moisture or water.

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.
