The Whitelaw 2 Series LED downlight is designed for commercial applications requiring robust, attractive, recessed lighting. IP65 ingress protection ensures that moisture-rich environments and areas subject to routine wash downs do not compromise product performance and longevity.
Typical applications include lighting for swimming pools, changing rooms, healthcare, and wash facilities.
A range of outputs (10-40W), sizes, and 3hr emergency options, make it well suited for delicate accent lighting and functional general lighting.
Where stylistic designs are appreciated, personalised accent halos can be offered to compliment internal and external architecture.

Polar: solid green C0–C180, dashed blue C90–C270, dotted amber the plane through the brightest direction when it lies between them; rings at 25% steps of the peak. Isolux: the footprint on the floor with the fitting aimed straight down, contours at 50%, 25% and 10% of the brightest point, grid in mounting heights (H). Both are drawn from the first measured file for that optic.
The Whitelaw 2 Series LED downlight is assembled with premium components, designed to provide a robust, attractive fitting. A recessed light engine ensures accurate light focus while simultaneously reducing glare. Chip & CRI - The Whitelaw series utilises Sanan LED chip in a recessed housing to produce optimal lighting and low glare performance. It offers the choice of colour rendering index of a high ≥80 which reproduces colours clearer compared to more common lower CRI. Chlorine Resistant Surface Finish and Ingress Protection - Waterproof IP65 power supply and IP65 chlorine resistant surface finish luminaire. With a protective gland to allow secure cable connecting to light fixture. Heat Sink - Upgraded patented design heat sink system improves upon traditional designs. It uses aluminium die casting materials for superior heat dissipation performance and avoids potential risk in working environments. Mounting - A key feature in the design of this product is installation, it uses a 2 point brace design, making it quick and simple install process while limiting damage. 10W - 50W Models (Cut Out Sizes Vary) - a wide range of lumen outputs offers suitability for general lighting, and accent lighting. 3 Hour Emergency Options - 3hr Remote-test and DALI Self-Test options offer flexibility for general and emergency lighting. Optional Custom-Colour Faceplate - front face-plate can be custom-coloured to suit project requirements.
