Valoya LED units are high quality, commercial grade lighting systems that are built to exacting standards in order to offer a long and stable service life. Whilst LED lighting is significantly cooler running then HID or even fluorescent lighting, an optimal temperature must be maintained within the unit to ensure a consistent quality of light in both overall output and spectrum. The majority of LED luminaires available achieve this by means of computer cooling fans, which can be both noisy and prone to failures. The Valoya range of LED manages to maintain a stable internal temperature without the use of fans by having more than adequate heat sink capabilities. This ensures not only a very stable light source, but also goes a long way to providing a long life span (>50,000 hours). This also means that Valoya lighting systems have a very high ingress protection rating (IP), which make them perfectly suited for use in schools and research facilities that require this level of safety.
