Thorlux Lighting’s latest pendant, the Strike M, has achieved a 2.5 ‘excellent’ circularity score in the Cibse TM66 circularity measure.
The rating means that the suspended spotlight demonstrates long-lasting, efficient, and reusable qualities.
The company says it is dedicated to the principles of the circular economy and designs all new products guided by the TM66 framework. This encompasses material selection, performance optimisation, recyclability, and more.
The adaptable design features interchangeable, low-glare optics, a choice of beam angles to provide a smooth distribution and reduce spill light and an LED with colour rendering of 90CRI.
TM66, a ‘technical memorandum’, was introduced by Cibse’s Society of Light and Lighting in 2021.
The metric, which measures the circular performance of luminaire, has been in a preliminary ‘beta mode’ since its introduction.
The document won a prestigious Build Back Better Award on its publication on its publication in 2021 and was quickly adopted by the lighting industry.
Major lighting design practices and organisations are using the metric in their procurement and specification policies, and many manufacturers have rated their luminaires on the TM66 scale, which gives a number between 1 and 4 similar to a vehicle’s NCAP safety rating.
Now the TM66 development team, the founding partners and parallel organisations are set to gather to work the official first version of the standard.
An update will be presented in September at the Circular Lighting Live 2025 event in London on Thursday 25 September.
Sections of the document likely to change include:
• Materiality, the identification and appropriately scoring of those aspects of a luminaire’s design, materials, construction or ecosystem that have the most impact on circularity
• Precision and transparency, especially related to language, reporting and evidence
• Greenwashing, the reduction of the possibilities of the metric being used to make misleading or false claims about the environmental benefits of a light fitting.
• Learn about TM66 at Circular Lighting Live 2025, Recolight’s flagship conference and exhibition, which takes place on Thursday 25 September 2025 at the Minster Building in the City of London. Free to specifiers, Circular Lighting Live 2025 will feature leading experts, specifiers and policy makers who will share their insights into forthcoming standards and legislation, emerging technologies and new business models. Thorlux Lighting is a gold sponsor and will be exhibiting at the event. More info: www.circularlighting.live
