Design and Development


3D computer-aided design is used to develop and model new products with high specification materials and components. Computer simulation techniques are also used to achieve the photometric performance required. Pre-production models are fully assessed for electrical, thermal and mechanical characteristics before final production.

Product Testing

Rigorous product testing is essential in maintaining our reputation for reliability and quality. Testing covers all aspects of environmental and electrical parameters including extreme ambient temperatures, dust/water ingress, EMC and current harmonics to comply with relevant International standards.

Photometric Data

Our Lighting Photometric Laboratory houses a sophisticated goniophotometer for fast and reliable measurement of luminaire light distribution. An integrating sphere equipped with spectral analyser enables accurate measurement of light quality, efficiency and colour temperature.

LED Prototyping

In-house rapid prototyping of LED printed circuit boards reduces development lead times. New circuit board designs can be trialled within hours of the initial concept and put into production within just a few weeks. Huge investment in LED technology includes circuit board design, software development, thermal modelling and optical lens design puts Guanke at the forefront of its market sector.
