Our Company
SunTracker develops advanced professional lighting design software for the global lighting industry. Our Helios lighting calculation engine is the industry benchmark, trusted by designers and engineers for its scientific precision, rigour, and robust computational engine. In 1997, our co-founder and Senior Scientist, Ian Ashdown, developed Helios, which was subsequently licensed to Lighting Analysts (now part of Revalize) for integration into AGi32, ElumTools, and Licaso, and to Glamox AS (Molde, Norway) for its OptiWin 3D Pro lighting design software. The computational framework introduced in Helios has been continuously developed for more than three decades, resulting in the Cerise365 lighting calculation engine.
In 2015, SunTracker was awarded its first patent for predictive daylighting. Today, our intellectual property portfolio comprises more than 40 issued patents worldwide, covering advanced photometric analysis, horticultural illumination, real-time simulation, and next-generation controls.
SunTracker has received awards from ASABE (2023) and the Illuminating Engineering Society (IES) (2022) for its Cerise365+GreenHouseDesigner software, which incorporates sophisticated radiometric modelling for horticultural lighting.
Today, SunTracker stands at the forefront of computational lighting science, driving innovation across horticultural, architectural, health, and entertainment lighting design with tools that merge rigorous physics with modern software engineering.
