Product Description

The Lightway Maximus 5000 is perfect for daytime lighting in commercial applications, such as industrial halls, offices, sales areas, and warehouses. It contains a pre-assembled skylight, making installation quick and simple (only 15 minutes per set). Installation does not require a specialised company, or specific training, only a simple manual. It also contains an integrated thermal block Lightway Blue Performance 0.7 W/m²K, allowing you to control the temperature in your building. In Winter, the Maximus 5000 greatly reduces heat loss, while in Summer months, the internal spaces will not be heated and will not allow transmission of infared light.

Why choose a commercial sun tunnel?

Natural daylight has a multitude of positive affects, compared to artificial lighting. Lightway fulfills hygienic norms for daylighting, and healthy daylight can result in lower frequency of illness, increased concentration and enthusiasm, and healthier eyes and physical condition.

To light a 10 000m² hall, 50 sets of Lightway Maximus 5000 are necessary. This replaces 350 electric LED lights, with an output of 350 x 144W. Therefore, you can light your halls for free, with a return investment of only 5 years.

Light uniformity

The Maximus 5000 has effective diffusers, which give greater uniformity of daylighting. They provide better light distribution compared to classic skylights, specifically, substituting 3-5m² of classic glass surfaces. At night, the LED hybrid system provides the same amount of light, mimicking natural daylight.
