Vmax has the qualification of national recognized laboratory, and the reports of photoelectric color parameters of products issued by Vmax are recognized by the state. The quality is strictly controlled and the product quality is fully guaranteed.

According to the requirements, the working environment temperature of the product lamp can be set, and the junction temperature data of each component of the product can be tested under the ambient temperature, and the curve chart can be generated, which provides the basis for product design and performance evaluation.

Test the flux, color temperature, wavelength, color index, color temperature, color purity, current, voltage, power, etc. of the lamp beads, inspect whether the sample lamp beads provided by the supplier are qualified and confirm the lamp bead performance, so as to provide basis for research and design.

Vmax has the first-class domestic and world-class vertical distribution photometer, which can accurately test the light spatial distribution pattern and beam angle of lamps and other parameters. Through the vertical distribution photometer, it can design a good light distribution effect for different occasions.

Simulate the surge voltage generated in the power grid due to lightning stroke, equipment switch, electrostatic discharge and line fault, test the product's ability of anti lightning surge injury, facilitate analysis, comparison and product debugging, suitable for technical development and product inspection.

Simulate the transient high voltage generated in the power grid and test the high voltage resistance of the product. It is used to test the electrical safety performance of the product under the actual working condition, and is one of the important indexes to test the electrical safety performance of the equipment.

The test power supply and control switch switching (or caused by lightning stroke) produce transient phenomenon, and generate ring wave interference on power line, control line and signal line, which is convenient for analysis, comparison and product debugging, and suitable for technical development and product inspection.
