Description
Why choose the Square LED Surface Downlight 18W
At under €10, this fitting offers a straightforward, no-fuss upgrade for any space that currently runs on outdated incandescent or compact fluorescent ceiling lights. The low-profile 32 mm body sits flush against the ceiling without requiring a recess, and the aluminium housing dissipates heat efficiently to protect the light source over its 30,000-hour lifespan. It is a practical choice wherever a clean, square aesthetic and reliable daylight-white output are needed.
- Efficiency: At 80 lm/W, the 18W draw replaces a 50W fitting, cutting ceiling-light energy consumption by roughly 64% with no reduction in perceived brightness.
- Light quality: A CRI of Ra>80 renders colours accurately enough for task areas, product displays and reception counters where visual clarity matters.
- Build: The white-painted aluminium body is rated for operating temperatures from -20 to 55°C, making it suitable for unheated storage rooms and stairwells as well as air-conditioned offices.
- Simplicity: Surface mounting with a standard on/off driver means installation requires no ceiling void, no driver box and no additional wiring accessories — connect directly to a 200–240V AC supply.
Where to use it
This fitting is well suited to offices, open-plan workspaces, school classrooms, corridors, stairwells, utility rooms and small retail back-of-house areas. At a typical mounting height of 2.5–3 metres, a single unit covers a working area of approximately 3×3 metres. For larger rooms, multiple units on a regular grid will achieve comfortable general illumination without dark spots.
What the specifications mean in practice
- 6000K: Daylight-white light that promotes alertness and visual acuity — well suited to task-focused environments such as offices and classrooms, though warmer alternatives may be preferable in hospitality settings.
- 80 lm/W: Every watt consumed produces 80 lumens of useful light, translating directly into lower electricity bills compared with the 50W fitting this unit replaces.
- UGR<22: Glare is controlled to a level acceptable for general circulation and utility areas; for intensive screen-based work, a fitting with UGR<19 would be the preferred specification.
- IP41: Protected against solid objects larger than 1 mm and dripping water falling vertically — suitable for indoor dry and semi-dry locations, but not for bathrooms, kitchens or outdoor use.
- 30,000 hours: Running eight hours a day, this fitting will last approximately ten years before lumen output drops to 70% of its original value, keeping maintenance calls to a minimum.
Installation and compatibility
The fitting mounts directly to any flat ceiling surface using the integrated back plate — no ceiling void is required. It connects to a standard 200–240V AC supply via the built-in on/off driver; dimming is not supported. Clightstore provides a free DIALux light study on request to confirm spacing and lux levels before you order.
Frequently asked questions
Can this downlight be dimmed?
No. The integrated driver is on/off only and is not compatible with leading-edge, trailing-edge or DALI dimmers. If dimming control is a requirement, please contact Clightstore for alternative models.
How many fittings do I need for a standard office room?
For a room of roughly 20 m² at a 2.7 m ceiling height, four units on a regular grid typically achieve around 300–400 lux. A free DIALux study from Clightstore will give you an accurate layout for your specific space.
Is this fitting suitable for a bathroom or outdoor canopy?
No. The IP41 rating covers indoor dry and semi-dry locations only. Bathrooms, covered outdoor areas and any space exposed to splashing water require a minimum of IP44 or IP65 depending on the zone.
