Background: Initially, the CDO lamp test was not added at the beginning of the project establishment. Later, during the CRA project process, it was proposed that this test needed to be added. Due to the tight supply of 70W lighting positions at the beginning, the team chose the T35 50W(928082419235) model as the Carrier. Despite numerous inquiries, the inner tube of this model has not been available and will have to wait until mid-October.
