Collingwood DLE4357040 Description

The Collingwood Lighting DLE4357040 H4 Pro 550 is a premium adjustable LED downlight designed for modern residential and commercial lighting applications where wider light distribution is required. Combining the proven performance of the H2 Pro range with enhanced adjustability, this fitting is ideal for general lighting in kitchens, bathrooms, hallways, and open-plan spaces.

Emitting approximately 550–580 lumens of cool white 4000K light from just 5.2W, this energy-efficient downlight delivers bright, clean illumination suitable for task-oriented and contemporary environments. The wide 70° beam angle ensures broad, even light coverage, reducing shadows and creating a more uniform lighting effect across larger areas.

The adjustable 20° tilt function allows for directional lighting when needed, offering flexibility for both general and accent lighting applications. Built for durability and compliance, the H4 Pro 550 is IP65 rated, making it suitable for bathroom zones and damp environments, and is fully fire-rated for 30, 60, and 90-minute ceilings to maintain structural integrity.

Featuring Collingwood’s Easy-Fit connector and a shallow 49–50mm depth, installation is quick and simple, even in tight ceiling voids. Supplied without a bezel, it allows complete flexibility to select a compatible finish to suit your interior design.
