Good to know … - Information about our Circulus HCL products

With our Circulus LED modules, we offer ring-shaped HCL LED modules that are fitted with warm white and cool white LEDs in two separate channels. You can choose from five different diameters: Circulus D50, Circulus D105, Circulus D160, Circulus D215 and Circulus D270. All five diameters have a uniform ring width of 25 mm.

For optimum thermal management and high efficiency with a long service life, all Circulus modules are based on high-quality aluminum core circuit boards. The cutting-edge LED gives the Circulus modules efficiencies of up to 216 lm/W or light quantities of over 5,000 lm. The LED pitch is virtually the same for all modules.

Expansion of the Circulus LED module family – the new Circulus T5R HCL ring lights

The Circulus T5R HCL series expands the proven Circulus LED module family with a powerful, tunable white solution for human-centric lighting (HCL). The modules are specially designed for applications where light quality, biological effectiveness, and energy efficiency are paramount.

The Circulus T5R HCL series was designed as a direct replacement for T5 ring tubes.

Available in diameters of Ø 214 mm, Ø 289 mm, and Ø 363 mm, the modules cover a wide range of applications from workplace and office lighting to education and healthcare areas to retail and hospitality solutions.

Your benefits at a glance:

The new Circulus Ulla HCL – Uplight for Downlights

Circulus Ulla HCL and Ledil‘s Ulla optics create a lighting solution that combines design, technology, and flexibility in one clear system. The LED module was developed as an uplight for pendant downlights, especially for delicate luminaires, and produces a balanced, uniform light pattern for modern room concepts. The flat uplight avoids hotspots and distributes the light widely across the ceiling. Hard light cones and strong contrasts are avoided, the ceiling appears brighter, and the room appears larger. In combination with the downlight, this creates pleasant lighting that supports the room without dominating it – a conscious alternative to classic LED spots.

Circulus Ulla also impresses with its high technical quality and versatile application options:
