Located in Sydney, New South Wales, Australia, and established in 1885, Abbotsleigh serves as an independent boarding school that reportedly offers a well-balanced education. The school aims to empower their students to be courageous, compassionate, and constructive. Abbotsleigh School has been working on upgrading their concert and assembly hall lighting systems. For part of the renovation project led by the systems integration team at Barbizon Lighting Company’s Australia office, Chalice LED 150W downlights from Altman Lighting were used to upgrade the house lighting systems in the concert hall.
Barbizon Lighting Company Australia systems sales director Paul Lewis created a retrofit house lighting solution using the Altman Lighting’s mains-dimmable Chalice LED 150W downlights.
“We first came to this project while conducting a review of all the lighting fixtures and systems for the various venues within the school, and then preparing a schedule for renovations over a 2 to 3-year period,” began Paul Lewis, systems sales director for Barbizon Lighting Company in Australia. “The overall scope involved upgrading the fixtures to LED and updating the associated control systems as well. Stage one was previously comprised of installing Altman PHX 250W LED profiles in a few difficult to service front-of-house positions, along with Spectra Cyc 100 LED fixtures installed in the main assembly hall and the concert hall. Stage two was now being able to replace the existing house and work lighting fixtures in the concert hall with the new Chalice LED.”
Altman Lighting Chalice LED Series Includes Diverse Range of Downlights
The Altman Lighting Chalice LED Series offers a range of downlights that are available with mounting options including pendant, recessed, aircraft cable, wall, and yoke mount. The Chalice LED Series also features dimming choices ranging from mains dimming to DMX. Altman Lighting says that the fixtures come in wide variety of LED white or color light options, and offer numerous reflector or lens choices.
Lewis continued, “For the replacement of the house lights in the concert hall, the main challenges were needing to utilize both the existing house light positions and the existing power infrastructure, including dimmers and mounting methods. Additionally, we had the challenge of accessing the overhead concrete slab that would prevent the installation of any new DMX infrastructure. The fittings needed to dim smoothly on mains power, plus be able to be suspended from the existing penetrations in the slab. The Chalice LED downlights were ideal for this type of job, and since we are the Altman distributors for Australia, it was a natural choice.”
With the design solution now in place, Lewis and his team began the installation of the new house lighting system. The system had to operate efficiently within the control protocols already in place, and Altman Lighting says that the Chalice LED downlights provided a simple and powerful retrofitted lighting solution.
“There are now 24 Chalice 150W Mains Dim 2700K luminaires suspended on aircraft cable in a one-for-one replacement of the tungsten fixtures from the original build,” added Lewis. “They are all being dimmed via the existing dimming system, and they are easily controlled by either the architectural, A/V, or stage lighting control system.”
Now finished, the new house lighting system in the concert hall at Abbotsleigh delivers both the performance and the design aesthetics the school wanted. The fact that the system works with both mains dimming and DMX protocols, makes Lewis sure that they installed the perfect lighting solution with the Chalice LED series from Altman Lighting.
“The Altman Chalice 150 is a beautiful fixture from both a light output and industrial design perspective,” concluded Lewis. “With its single source and reflector optic, plus its clean and simple lines, the Chalice downlight allows a venue to upgrade to LED lighting using their existing infrastructure and conventional dimming, or allows a venue to control via DMX or a combination of both. Also, the optional dimming curves available on the DMX model allow for a very smooth dimming that replicates very closely the smoothness of a fade on a tungsten lamp, minus the color shift of course.”
