Slim Flat LED Ceiling Panel Downlight 3CCT 220mm 330mm 18W 24W

The ILED-PRS-18W/24W C is a slim round LED ceiling panel downlight designed for indoor commercial and residential interiors. At just 19mm thick, it sits nearly flush with the ceiling surface, creating a clean minimalist look that works well in spaces where a bulky downlight would feel out of place. The product comes in two sizes: the φ220mm 18W model for smaller rooms and the φ330mm 24W model for larger areas, both delivering 100 lumens per watt. The round form factor suits circular ceiling layouts and central-room placements where a square panel would look misaligned.

Tech specs

The 18W version produces 1800 lumens and the 24W version produces 2400 lumens, giving a consistent 100 lumens per watt across the range. The 3CCT switch is accessible after installation and lets you select between 3000K warm white, 4000K neutral white, and 5000K cool white — one SKU covers all three colour temperatures without needing separate stock. CRI exceeds 80, so colours in the space render naturally without looking washed out. The power factor is above 0.9, meaning the driver draws current efficiently. Input voltage is 220–240VAC at 50/60 Hz; this is not a universal-voltage product, so projects in 110V regions need a transformer. The IP42 rating means the fitting is protected against dripping water and solid objects larger than 12.5 mm, which is suitable for indoor dry locations only. It is not rated for damp or wet areas.

Optical system and light distribution

The PMMA diffuser scatters light evenly across the beam, reducing hot spots and glare that can occur with uncovered LED panels. The beam angle is 120°, producing a wide wash of light that covers the floor area beneath and slightly beyond each fitting. With 100 lumens per watt, the 18W model puts out roughly 1800 lumens and the 24W model roughly 2400 lumens — figures that match the spec table and are consistent with what installers see on site. The diffuse output makes this panel useful for general ambient lighting where uniformity matters more than accent or task lighting.

Build and installation

The housing is made from PC (polycarbonate) with an aluminum head heat sink. The PCB board is adhered directly to the aluminum sheet, which draws heat away from the LEDs and keeps lumen maintenance stable over time. The PC body is UL94V0 rated for fire resistance. The diffuser is PMMA, which transmits light efficiently while resisting yellowing better than cheaper alternatives. Two mounting methods are available: surface mount, which uses the included ring and is suitable for existing ceilings where no cut-out is desired, and recessed mount, which uses flexible brackets and requires a circular cut-out in the ceiling. The recessed option gives a cleaner finished look but needs access from above the ceiling cavity. The aluminum heat sink is visible from the rear and helps dissipate heat into the ceiling void, extending LED life. The PC body resists impact better than aluminum housings during handling and installation.

Sertifikāti un garantija

The ILED-PRS-18W/24W C carries SAA, CE, and RoHS certifications, covering electrical safety, electromagnetic compatibility, and restriction of hazardous substances. The standard warranty is 2–3 years depending on the market and installer conditions. For projects requiring longer warranty coverage, contact the sales team before ordering. The SAA mark is required for most Australian and New Zealand installations and is verified on the spec table. CE marking confirms compliance with EU low-voltage and EMC directives for European markets.

Why do buyers pick the ILED-PRS-18W/24W C over other slim panels? Here is what we hear from customers:

19mm profile. — One of the thinnest round panels in this category. Installers note it sits almost flush with the ceiling, which matters in low-clearance rooms.

100 lumens per watt on both sizes. — No drop-off between the 18W and 24W models. Buyers appreciate the consistent efficiency across the range.

3CCT built in. — 3000K, 4000K, and 5000K from one SKU. Specifiers value not having to hold three colour-temperature SKUs in stock.

Two mounting options. — Surface mount with the ring or recessed with flexible brackets. This covers both new-build and retrofit projects without needing a different product.

SAA certified. — Required for most Australian and New Zealand projects. The SAA mark is listed on the spec table and confirmed at checkout.

Residential bedrooms and living rooms. — The 19mm profile and neutral colour temperature options make this panel a natural choice for rooms where a low-profile ceiling light is preferred over a protruding downlight.

Offices and co-working spaces. — 100 lumens per watt and CRI above 80 deliver comfortable, accurate illumination for desk work and meeting areas. The wide 120° beam angle reduces the number of fittings needed per square metre.

Retail stores and showrooms. — Accurate colour rendering (CRI >80) helps products look their best under the light. The slim form factor keeps attention on the merchandise rather than the fitting.

Hospitality corridors and guest rooms. — The 3CCT switch lets hotel designers adjust colour temperature during commissioning to match the brand’s lighting identity, without swapping out fixtures.

Educational classrooms and libraries. — Even light distribution and flicker-free operation create a comfortable reading and study environment. The UL94V0-rated body meets school fire-safety requirements.

Healthcare waiting areas and clinics. — CRI above 80 supports accurate colour perception in spaces where skin tones and material colours matter. IP42 is sufficient for dry indoor clinical environments.

A few things to check before ordering the ILED-PRS-18W/24W C:

Mounting method. — Confirm whether surface mount or recessed mount is needed. Recessed installation requires a circular cut-out and access from above the ceiling.

Voltage. — This model accepts 220–240VAC only. Verify the local mains voltage before ordering. If your site runs at 110V, request a compatible variant or plan for a transformer.

Colour temperature at order. — While the 3CCT switch allows post-installation selection, confirm the target colour temperature with the client before shipping, especially for large orders where returns are costly.

IP42 — indoor use only. — Do not specify this product for bathrooms, outdoor canopies, or any damp location. Choose an IP65-rated product for those applications.

Dimming requirement. — The standard driver is non-dimmable. If your project requires dimming, confirm dimmable variants are available before finalising the order.

Packaging. — Units ship in cartons sized for the φ220mm and φ330mm formats. Confirm carton quantities with the sales team for bulk orders.
