SpectrumLED DURE 3 recessed LED downlight, white square, 18 W 3000 K IP54, SLI043011WW_PW

SpectrumLED DURE 3 SLI043011WW_PW is a white, square LED downlight designed for recessed ceiling installation. A broad frame surrounds its flat illuminated panel, while the polystyrene housing measures 170 × 170 × 34 mm. This version provides warm white 3000 K light and has an integrated driver.

Check the ceiling opening first

Installation requires a 145 × 145 mm cut-out. That measurement is different from the outer frame size, so when replacing an existing fitting, compare both the opening and the space available for the housing. The 34 mm height describes the fitting itself, not a guaranteed total installation clearance including its electrical connection.

The rear photograph shows spring clips and a connection lead. The downlight operates on 230 V. Its manual requires a qualified electrician to carry out installation and connection work with the power disconnected. The housing must not be covered with thermal insulation.

Warm, broad light without dimming

The LED light source is included, so there is no separate bulb to select. Power is 18 W, and the 110° beam provides a broad spread rather than a narrow accent. That distinction matters when planning kitchen or circulation lighting: the spacing of fittings needs to suit the actual area being lit.

The manufacturer lists 1600 lm for the luminaire and separately 2200 lm for the LED source used inside it. Use the first figure when comparing complete fittings. This version is not dimmable and cannot be operated with a brightness dimmer. Its 3000 K rating specifies a warm light colour, not a selectable colour-temperature setting.

Indoor placement and care

The official applications include bathrooms, kitchens and indoor circulation areas. IP54 does not authorize installation anywhere in a bathroom; the chosen position must meet the requirements of the electrical installation. The white finish, square outline and lack of decorative detailing suit modern, minimalist interiors.

After switching off and allowing the fitting to cool, remove dirt with a soft, damp cloth. The instructions rule out aggressive cleaning agents and opening the housing.
