The compact fire-rated downlight has been designed to deliver both safety and performance in a small form factor, making it an ideal choice for demanding environments. It completes the Chalice range with a smaller size, extending the family’s flexibility into applications where space or installation conditions present a challenge. Built to withstand tough conditions, it carries an IP65 rating from below, ensuring reliable protection against dust and moisture, and is particularly well suited for use in hotels, residential areas, restrooms, and bathrooms.
Ease of installation has been prioritized in its design. The downlight comes equipped with a detachable connector box that enables simple, tool-free pre-wiring via a push-fit terminal block. This makes installation straightforward and efficient across a wide variety of ceiling types with thicknesses from 1 mm to 25 mm. The product’s compact overall height of under 100 mm ensures it can fit comfortably in restricted ceiling voids, while the 74–80 mm cut-out size adds further flexibility for retrofit or new-build projects.
Customization is another key feature of this luminaire. Exchangeable lenses and bezels allow the downlight to be tailored on site to suit different interior design styles or functional requirements. A range of bezel finishes is available, including matt white, gloss white, matt black, chrome, and brushed aluminium, ensuring that the fixture can blend seamlessly with diverse architectural settings.
The luminaire is constructed with durability and performance in mind. Its housing and body are made from steel, combined with an aluminium heatsink covered by a protective polycarbonate cap. The lens is crafted from PMMA for optical clarity and efficiency, while the bezel is produced from robust die-cast aluminium to provide strength as well as an attractive finish.
Performance is equally strong, with fixed output options offering correlated colour temperatures of either 3000 K or 4000 K, a colour rendering index (CRI) above 80, and a chromaticity tolerance of three steps. Two lumen packages are available—550 lm and 900 lm—allowing designers and installers to select the right level of illumination for the space. The downlight’s operational life is rated at 50,000 hours (L70) at a temperature of 25°C, ensuring reliability and long-term performance.
Overall, this fire-rated IP65 downlight combines compact size, robust construction, customization options, and ease of installation, making it a versatile and dependable choice for moisture-prone environments and modern architectural spaces that demand both functionality and design flexibility.
