Product FAQs
Circa specification questions.
Specification notes for contractors, consultants and buyers checking low-glare LED downlight options before ordering.
What makes Circa different from a standard low-glare LED downlight?
The Circa LED Downlight is a cuttingâ€edge, lowâ€glare luminaire designed for high-end architectural and commercial applications. Meticulously engineered for superior energy efficiency and sustainability, the Circa is ideally suited to green building projects and meets the rigorous demands of LEED and BREEAM accredited developments
Which ceilings or mounting conditions should be checked for Circa?
Check the mounting method, ceiling construction, access space and installation guide before the luminaire is added to the final schedule.
Which outputs, wattages and colour temperatures are available?
Outputs up to 4600 lm: Output reference for specification and comparison. Life >50,000 hours (L90): Long-life LED performance. Output, colour temperature, control gear and emergency options vary by configuration.
What controls and emergency options can be specified?
Controls: Mains dimming /MDIM, DALI / SwitchDIM / DSI /ECO and Casambi wireless /BTC. Emergency: 3-hour emergency /EM and Self-test / DALI emergency /EMD. Confirm compatibility with the project control strategy, emergency schedule and selected base model before quotation.
Can finishes, accessories or product variations be specified?
Finish, accessory and project variation requirements should be confirmed before quotation, especially where non-standard colours, plug-and-socket arrangements or controls are required.
Are photometric, BIM or installation files available?
Available files include the datasheet, installation guide, photometric data and BIM file for specification work, coordination and installation planning.
What lead time should be allowed for Circa?
Lead time depends on quantity, finish, control gear, emergency conversion and current production capacity. Confirm the current project lead time with Lumenloop before placing an order.
