Frequently Asked Questions
Can this fixture be safely recessed directly into the ceiling?
No, the Astro Kos Round 140 is strictly a ceiling surface-mounted downlight. It is explicitly designed to sit flush against the surface of a finished ceiling, making it a perfect decorative feature and alternative to traditional cut-out recessed spots.
Is the GU10 bulb included with the fixture?
No, the light source is sold separately. The fitting requires one energy-efficient LED GU10 bulb with a maximum wattage of 6W and a maximum physical length of 60mm, allowing you to select your preferred beam angle and colour temperature.
Is the light dimmable?
Yes. It is dimmable when used with a compatible dimmable GU10 LED lamp and a suitable LED dimmer switch.
Who can install this?
This light fitting must be installed by a qualified electrician in accordance with current UK Wiring Regulations (BS 7671). As a fixed mains-powered outdoor luminaire, professional installation ensures correct earthing, safe wiring connections, and full compliance with IP44 weather protection standards.
Who needs this light fitting and where to install it?
The Astro Kos Round 140 Coastal is ideal for homeowners, architects, and commercial developers looking for a clean, architectural outdoor lighting solution. It is especially suited to projects where a discreet, modern design is required alongside reliable performance in exposed conditions.
It can be installed in covered entrances, porches, patios, balconies, external corridors, soffits, garden structures, and commercial façades. Its soft downward illumination makes it perfect for creating ambient lighting, improving visibility, and enhancing architectural features without overpowering the space. Thanks to its coastal-rated construction, it is also highly suitable for seaside homes, hospitality venues, and waterfront developments.
What else do you need with this?
To complete installation, you will typically need:
- 1 × GU10 LED lamp (max 6W, max 60mm length)
- Dimmable GU10 LED bulb (if dimming is required)
- Compatible LED dimmer switch (optional)
- Professional outdoor-rated wiring accessories (installed by an electrician)
For larger projects, this fitting pairs well with other Astro Coastal ranges such as Mast Coastal, Mast Twin Coastal, and other Kos Round Coastal finishes to create a consistent architectural lighting scheme.
