Round LED Recessed Downlight 18W 4000K Neutral White – 80 lm/W – Cut-Out Ø145-155mm – For Kitchen, Hallway & Office – 3-Year Warranty

Why choose the Round LED Recessed Downlight 18W

At under €8 per fitting, this 18W downlight offers a straightforward, no-fuss solution for high-volume recessed lighting projects. The aluminium body dissipates heat efficiently, protecting the LED module and keeping lumen maintenance high over the fitting's lifetime. CE and RoHS certification confirms compliance for commercial and residential installations across the EU.

• Efficiency: At 80 lm/W, the fitting draws just 18W while producing 1,440 lumens — cutting energy consumption by up to 82% compared with a 100W incandescent equivalent.
• Light quality: 4000K neutral white provides a clean, balanced tone that renders colours accurately without the harshness of cool white, making it suitable for both task and ambient lighting.
• Build: The die-cast aluminium housing acts as a passive heatsink, keeping junction temperatures low and supporting the rated 50,000-hour lifespan without active cooling.
• Warranty: A 3-year warranty and CE/RoHS certification give installers and facility managers confidence in long-term performance and regulatory compliance.

Where to use it

This 18W downlight is well suited to ceiling heights of 2.4 to 3.5 metres in kitchens, hallways, corridors, open-plan offices, retail units and hotel rooms. At standard 2.7m ceiling height, a grid spacing of roughly 1.5 to 2 metres between fittings typically achieves 300–500 lux on the working plane — adequate for general office and kitchen task lighting.

What the specifications mean in practice

• 80 lm/W: For every watt consumed, the fitting produces 80 lumens — meaning lower electricity bills and a faster return on investment compared with older halogen or CFL downlights.
• 4000K: Neutral white light sits between warm and cool white, reducing eye fatigue during prolonged work while keeping the space feeling bright and professional rather than clinical.
• Ø145mm cut-out: Fits standard 145mm ceiling apertures common in new-build and retrofit projects, with the 155mm outer diameter providing a neat overlap to conceal any imperfections around the hole.
• 50,000 hours: Running 10 hours a day, the fitting lasts approximately 13 years before replacement is needed, significantly reducing maintenance call-outs and lamp replacement costs.
• -20 to 55°C operating range: The fitting performs reliably in unheated utility rooms, cold storage corridors and warm commercial kitchens without risk of premature failure.

Installation and compatibility

The fitting mounts into a Ø145mm ceiling cut-out using spring clips and connects directly to 220–240V mains via the integrated on/off driver — no external driver required. Dimming is not supported on this variant. Clightstore offers a free DIALux light study to confirm fitting quantity and spacing before you order.
