The Ideal Lux Atom 366821 is a compact outdoor LED wall light designed to cast light both upwards and downwards across an exterior wall. Its simple 10 cm cube-shaped body, grey finish and concealed integrated LED source suit contemporary entrances, patios, terraces and exterior wall lighting schemes where a neat architectural effect is preferred. The fitting combines a 12W integrated LED with a warm white 3000K colour temperature and an IP54 rating for outdoor use. Adjustable internal fins allow the width of the upper and lower light beams to be altered, making it possible to create anything from relatively narrow accents to broader washes of light on the wall.
The Atom has a compact geometric form measuring 10 cm high, 10 cm wide and 10 cm deep. Its aluminium body is finished in grey using a powder-coated finish, giving the fitting a clean, understated appearance suited to modern exterior architecture.
Glass diffusers are positioned at the top and bottom of the fitting, while the LED source remains concealed within the body. When illuminated, the light is directed against the wall rather than projected straight forwards, creating a defined architectural lighting effect above and below the fitting.
The integrated 12W LED produces warm white light at 3000K. The current product specification lists a light output of 1050 lumens, providing useful decorative and supplementary exterior illumination without requiring a separate replaceable bulb.
Light is emitted both upwards and downwards through the glass diffusers. Movable internal fins allow the width of each beam to be adjusted, so the wall-light pattern can be tailored after installation. Narrower settings can create more defined shafts of light, while opening the fins increases the spread across the wall.
An IP54 rating provides protection against dust ingress at a level suitable for the fitting and against splashing water from different directions, making the Atom suitable for appropriate outdoor wall locations.

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.
