The sun you have always wanted: sunshine day and night for accelerated light stability and weathering tests.

  1. Radiant energy in the SOLARBOX is provided by a single superior air-cooled Xenon Lamp generating an irradiance level up to two times the sun one. Irradiance is the rate at which light energy falls onto the samples. A weathering tester must control irradiance if it is to achieve accurate and reproducible test results. SOLARBOX offers constant measurement and control of irradiance during every test, compensating for lamp and UV filter ageing via a closed loop irradiance narrow-band sensor control system. Irradiation uniformity is guaranteed by a parabolic reflector chamber with the Xenon Lamp in the focus, the best design for a reliable flat-bed xenon exposure system and very good agreement with rotating drum xenon exposures.


A flooding system for conducting weathering tests with freely selectable flooding interval is an available option for SOLARBOX 1500e and 3000e:

 water level indicator
 continuous flooding possible
 flooding intervals selectable between 1 and 999 minutes throughout the test program 
 water temperature of 30°C to 50°C.

During flooding, the Xenon Lamp can be programmed on or off. The flooding system operates with demineralised water from a closed recycling circuit so to minimize the need of demineralised water but offering the same test results of a high consumption spray system. PVC and corrosion-resistant materials ensure long life of this tank pump system: capacity up to 50 litres.


  • SOLARBOX 1500/3000 standard versions include the following equipment:
  • − timer and time elapsed meter for accurate control of test sequence
  • − superior air cooled Xenon Lamp
  • − rotary knob to adjust irradiance level
  • − control system for constant irradiance
  • − basic 290 nm. filter for maximum UV radiation effect


TThe SOLARBOX 1500-1500e and SOLARBOX 3000-3000e are 4 ultimate filtered Xenon light exposure and weathering instruments which simulate realistic natural outdoor weathering conditions. The large dimensions of SOLARBOX 3000 and 3000e test chamber can accommodate 3 dimensional objects and finished industry products. Accelerating the process requires the accurate reproduction of the sun’s rays. The air cooled Xenon Lamp in the SOLARBOX replicates the total spectrum of the sun and not just the short wavelength UV, as we have using UVA or UVB fluorescent lamps. Easily interchangeable light filters allow the reproduction of the specific spectral distributions found in your product’s end-use environments.
