Astro Lighting 1252003 Osca Round 140 Paintable Plaster Ceiling Light

Astro Osca Round 140 Classic Paintable Plaster Ceiling Light – 1252003

Create a clean, contemporary ceiling-lighting feature with the Astro Osca Round 140 Classic 1252003. Manufactured from white plaster, this cylindrical surface-mounted ceiling downlight can be painted to coordinate with the surrounding ceiling, interior colour scheme or architectural finish.

Its simple round form makes it suitable for residential, hospitality and commercial interiors where a modern ceiling spotlight is required without the appearance of a conventional metal downlight. The plaster construction gives the Osca Round 140 a seamless architectural character that works particularly well in minimalist homes, modern apartments, hotel bedrooms, restaurants, hallways and contemporary living spaces.

The light uses one replaceable GU10 LED lamp, allowing the customer or installer to choose the preferred brightness, colour temperature, beam angle and dimming performance.

Paintable White Plaster Ceiling Light

Product code 1252003 is supplied in a white plaster finish that can be painted after suitable preparation.

Painting the fitting to match the ceiling can create a discreet, built-in appearance. Alternatively, it can be finished in a contrasting colour to create a more noticeable decorative ceiling feature.

The paintable plaster construction makes the Astro Osca Round 140 suitable for:

• White and neutral ceilings
• Dark or coloured feature ceilings
• Contemporary living rooms
• Modern bedrooms
• Residential hallways
• Hotel guest rooms
• Restaurants and bars
• Apartment developments
• Commercial reception areas
• Minimalist interior projects
• Architectural lighting schemes

The fitting should be prepared and painted according to Astro’s official plaster-light painting guidance. Paint should not obstruct the lamp opening, electrical components or ventilation areas.

Surface-Mounted Ceiling Downlight

The Osca Round 140 is a surface-mounted ceiling light rather than a recessed downlight. It does not require a large ceiling cut-out or deep ceiling void.

Its cylindrical body projects approximately 140mm below the ceiling, creating a clean architectural spotlight effect. This makes it useful where recessed lighting is not practical because of shallow ceiling voids, concrete ceilings or installation restrictions.

A surface-mounted ceiling spotlight can also create a stronger decorative presence than a conventional recessed fitting while maintaining a simple, uncluttered design.

Replaceable GU10 LED Lamp

The Astro Osca Round 140 requires one GU10 LED lamp with a maximum power of 6W. The lamp is sold separately.

Using a replaceable GU10 lamp allows the lighting specification to be adapted to the room. Customers and installers can select the preferred:

• Lumen output
• Colour temperature
• Beam angle
• Colour-rendering performance
• Dimming capability
• Energy consumption
• Lamp lifespan

The selected GU10 lamp must not exceed 100mm in length, providing compatibility with a wider range of elongated GU10 LED lamps than many compact downlights.

Suitable lamp options include:

• 2700K GU10 LED for warm decorative lighting
• 3000K GU10 LED for clean warm-white illumination
• 4000K GU10 LED for cooler functional lighting
• High-CRI GU10 LED for improved colour appearance
• Narrow-beam GU10 for focused accent lighting
• Wide-beam GU10 for broader room illumination
• Dimmable GU10 LED for adjustable lighting levels

Dimmable Ceiling Spotlight

The Astro Osca Round 140 can be dimmed when fitted with a compatible dimmable GU10 LED lamp and connected to a suitable LED dimmer.

Dimmable operation allows the lighting level to be increased for practical activities or reduced to create softer evening ambience in bedrooms, living rooms, dining spaces, restaurants and hotel interiors.

Dimming performance is dependent on the selected GU10 lamp and control equipment. The bulb and dimmer should therefore be checked for compatibility before installation.

Lamp-Dependent Brightness and Colour Temperature

The Astro 1252003 does not contain an integrated LED. Its performance is determined by the GU10 LED lamp installed.

Lamp-dependent specifications include:

• Total lumen output
• Colour temperature
• CRI rating
• Beam angle
• Energy consumption
• Dimming performance
• Expected lamp lifetime

This replaceable-lamp design makes the fitting flexible and easier to maintain. The GU10 bulb can be changed if a different output, beam spread or colour temperature is required without replacing the complete ceiling light.

Focused Architectural Lighting

The cylindrical body helps direct light downwards, making the Osca Round 140 suitable for general, task and accent-lighting applications.

Depending on the GU10 beam angle selected, the fitting can be used to illuminate:

• Dining tables
• Kitchen islands in dry locations
• Bedside areas
• Hallway features
• Artwork and decorative objects
• Hotel-room furniture
• Reception desks
• Restaurant tables
• Retail displays
• Living-room seating areas

A narrow-beam GU10 creates a more concentrated spotlight, while a wide-beam lamp produces broader illumination across the room.

Compact Round Design

The Astro Osca Round 140 measures approximately:

• Height or projection: 140mm
• Diameter: 110mm
• Gross weight: approximately 1.26kg
• Maximum lamp length: 100mm

Its 110mm diameter provides a compact appearance, while the 140mm projection creates a distinctive surface-mounted cylindrical form.

Because the product is manufactured from plaster, suitable ceiling fixings must be selected for the ceiling construction and the fitting’s weight.

IP20 Interior Ceiling Light

The Astro Osca Round 140 has an IP20 rating and is intended for dry indoor environments.

It is suitable for living rooms, bedrooms, dining rooms, hallways, hotels, restaurants and other interior spaces where it will not be exposed to splashing water or excessive moisture.

IP20 does not provide rated protection against water, so the fitting should not be installed outdoors or in wet bathroom zones.

Suitable for Bathroom Zone 3

Astro lists the Osca Round 140 as suitable for bathroom zone 3.

This refers to dry bathroom areas outside the principal water-exposure zones. Because the fitting is IP20 rated, it must be positioned away from baths, showers, washbasins and other locations where splashing water may reach it.

The final installation position must comply with current bathroom electrical regulations.

Class I Earthed Construction

The Astro Osca Round 140 is a Class I earthed fitting, meaning a protective earth connection is required.

It is designed for a hardwired mains electrical connection and does not require a separate LED driver. The selected GU10 LED lamp operates through the fitting’s mains-powered lamp holder.

Installation should be completed by a suitably qualified electrician.

Unswitched Ceiling Light

The fitting does not include an integrated switch.

It must be controlled using an external:

• Wall switch
• Compatible LED dimmer
• Smart-lighting control
• Timer
• Building lighting-control system

Several Osca Round 140 fittings can be installed together and controlled from the same circuit, subject to the circuit design and connected load.
