This customer is a supplier of railway lamp in Netherlands. The company decided to establish its own lighting test laboratory to realize the needs of product development and quality control. The company pursues high -quality, high -precision optical measurement results, and hopes to accurately measure and analyze the Luminous Intensity Distribution. This customer has learned about our related products on a third -party website and confirmed a series of technical issues with us. This customer is more cautious and carefully. Since they have not worked with us before, they did not directly place an order to us. Instead of asking for purchase through our old customers. Although customers are not directly purchase from us, LISUN also directly provides customers with free after sales services support. Because the High Precision Rotation Luminaire Goniophotometer that the customer’s previous inquiry did not require testing the color parameters, they only purchased our standard LSG-1800A High ...
