The Architectural Lighting Donegal 65642 is a compact white LED flush ceiling light designed for practical, everyday illumination. Its low-profile form measures approximately 28.5 cm in diameter and sits just 9 cm from the ceiling, making it particularly useful where overhead space is limited. An integrated 12W LED produces 830 lumens at 4000K, providing a clear natural white light suitable for bathrooms, hallways, corridors, stairwells and other functional areas. The IP44 rating provides protection against splashing water, while the simple white finish and diffused face give the fitting a clean, understated appearance that works easily with modern interiors.
The Donegal has a simple round profile with a white metal base and white acrylic diffuser. Its restrained design keeps attention on the illumination rather than decorative detail, making it useful in spaces where a neat and unobtrusive ceiling light is preferred.
At approximately 28.5 cm across and only 9 cm high, the flush construction sits close to the ceiling. The all-white appearance also makes it easy to coordinate with white ceilings, bathroom fittings and contemporary utility spaces.
A built-in 12W LED light source produces 830 lumens, so there is no separate bulb to purchase or replace during installation. The 4000K colour temperature provides natural white illumination suited to practical spaces where clear general lighting is useful.
The broad acrylic diffuser covers the integrated LED source and distributes light through the face of the fitting rather than from a single exposed bulb. Its IP44 rating makes the Donegal suitable for appropriate bathroom applications as well as hallways, corridors and stairwells.

Does the Donegal 65642 need a separate bulb?
No. It has a built-in 12W LED light source, so a separate replaceable bulb is not required. The integrated LED produces a verified output of 830 lumens.
What colour light does it produce?
The integrated LED has a 4000K colour temperature, commonly described as natural white. This produces a clearer, less warm appearance than typical 2700K or 3000K household lighting and is well suited to functional areas.
Can the Donegal 65642 be used in a bathroom?
Yes, the fitting is IP44 rated and is intended for suitable bathroom applications. The exact installation position must still comply with applicable bathroom electrical regulations and the required IP rating for the chosen location.
Is it suitable for a low ceiling?
Its flush design is particularly useful where ceiling clearance matters. The fitting projects approximately 9 cm from the ceiling and measures around 28.5 cm in diameter, giving it a compact, low-profile form.

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.
