When is a surface-mounted downlight the right choice?

When there is no suspended ceiling, the ceiling is concrete or timber, or an industrial look is wanted. A recessed downlight needs a cut-out in the ceiling; a surface-mounted downlight is fixed directly to it.

How do I choose the beam angle?

A narrow beam (15°–24°) is for accents, a medium beam (30°–45°) for mixed use and a wide beam (60° and above) for general lighting. The higher the ceiling, the narrower the beam needed to bring the light to the floor.

Which colour temperature should I choose?

2700K or 3000K warm white is recommended for living areas, bedrooms, hotels and restaurants; 4000K neutral white for offices, shops, kitchens and bathrooms; 5000K and above cool white for warehouses, workshops and technical areas. Using the same colour temperature for all luminaires in a room gives a consistent look.

What is the DALI option for?

DALI is a protocol for digital lighting control. A luminaire with a DALI driver can be dimmed and connected to an automation system with scenes and time programmes. A standard (ON/OFF) luminaire is simply switched on and off.

What is the difference between the EU driver and the standard driver?

Both are protected constant-current drivers compatible with the luminaire. The EU option uses a European-made driver – preferred for projects whose specifications require one.

When will my order ship?

Lamptime luminaires are made to order with the colour temperature, housing colour and optic you choose and ship within 1–3 business days. For bulk orders we confirm the lead time before you order.

The Lamptime DC24 is a surface-mounted downlight for rooms without a suspended ceiling or with concrete ceilings. Its COB LED light source delivers strong, crisp light from a single point. It is used in cafés, restaurants, shops, offices and modern homes for both accent and general lighting.

The cylindrical body keeps the light source deep inside and reduces glare.

The housing is powder-coated die-cast aluminium. The light source is a COB LED rated for at least 100,000 hours, with a colour rendering index (CRI) above 80 for natural-looking colours. The glare rating is UGR 11. The constant-current driver is protected against overload, overvoltage, short circuit and overheating; the luminaire runs on 220–240 V AC with a power factor of PF>0.60 (P≤25W) / PF>0.95 (P≥25W). Protection rating IP20, electrical safety Class I; operating temperature -20 °C to +50 °C.

Choose a colour temperature between 2700K–6500K: warm white (2700–3000K) gives a cosy light in homes, hotels and restaurants; neutral white (4000K) suits workspaces such as offices, shops and kitchens; cool white (5000–6500K) is preferred for technical areas and warehouses. The housing is available in white and black. Optics: 15°, 30° and 45°; narrow beams are for accents and displays, wide beams for general lighting. With the DALI option, the luminaire connects to building automation and can be dimmed. On request it is supplied with a European-made (EU) driver instead of the standard driver.

The product is made to order by Lamptime in Türkiye and ships within 1–3 business days; it comes with a 2-year warranty. For projects, bulk orders or help choosing luminaires, write to us and we will find the right product together.
