Circular Lighting Report

Street light achieves ‘excellent’ TM66

DW Windsor Kirium

One of the first street lights to achieve an ‘excellent’ TM66 score for circularity has been unveiled by DW Windsor.

The Pro S version of its long-established Kirium range scored above 2.5 in the assessment method, putting it in the top bracket.

The luminaire was evaluated in the Circular Economy Assessment Method for manufacturers included in TM66, a Cibse Technical Memorandum. It’s a self-certified system comprising 66 questions under four categories: product design, manufacturing, materials and supporting ecosystem.

Each question is rated and then scored between 1-4, where 1 is status quo and 4 is outstanding.

At the end of the assessment a total is generated, and a high score indicates a lighting product with good to outstanding Circular Economy credentials.

The Kirium Pro S features a new lightweight design, which minimises material usage and reduces its overall carbon footprint. It was the company claims is a ‘market-leading’ efficiency of up to 192lm/W.

The Pro S has multiple LED configurations and a choice of 23 precision optics, targeting illumination to direct light only where it’s needed, offering comfort and safety for road lighting applications while also helping to protect local wildlife and surrounding areas.

The luminaire also has a 0 per cent ULOR (Upward Light Output Ratio) to help combat light pollution and minimise sky glow.

Kirium Pro S launches in two sizes, while a larger version is due for release in next spring. All models share a unified design language to provide a consistent appearance across schemes.
