Karizma Luce Launches Ultra-Low UGR Downlight
Karizma Luce introduced the Dodici, a recessed linear downlight with deep-set optics designed for ultra-low glare (UGR). The product targets the high-end office, hospitality, and gallery sectors, where specifiers increasingly prioritize visual comfort to meet WELL and LEED standards.
The push for low Unified Glare Rating (UGR) lighting is driven by its significant impact on occupant well-being, a key factor in human-centric design. High glare can cause eye strain, headaches, and stress, reducing productivity. Standards like WELL v2 and LEED v4.1 now include specific UGR limits, often requiring a UGR of less than 19 for regularly occupied spaces and sometimes as low as 16 to earn points. Beyond visual comfort, lighting strategies increasingly target circadian rhythm support, a core principle of WELL certification. This involves specifying light with a high Melanopic Equivalent Daylight Illuminance (m-EDI) during the day to promote alertness and lower levels in the evening to aid sleep. For instance, WELL v2 may require a minimum m-EDI of 150-250 lux at eye level for several hours to achieve certification points. Integrating luminaires into building automation systems via protocols like DALI-2 is becoming standard practice. DALI-2 allows for individual and group control of lights, enabling flexible reconfiguration of spaces without rewiring. This interoperable standard, defined by IEC 62386, also facilitates the connection of sensors and controls from different manufacturers, feeding data into the broader building management system. The lighting industry is also shifting toward circular economy principles, moving beyond just energy efficiency. This involves designing for durability, modularity, and repairability, making it easier to replace components and reducing waste. Life Cycle Assessments (LCAs) are now used to evaluate a luminaire's environmental impact from raw material extraction to end-of-life, with the use phase typically accounting for the largest impact. Design leadership in this evolving landscape requires a multidisciplinary approach. Leaders at firms like Arup and Light Collab emphasize a holistic, 24-hour design process that prioritizes daylight and supplements it with artificial light. This strategy involves early collaboration with architects to integrate lighting with building form, a trend frequently covered in publications like *Dezeen* and *Architect Magazine*.
