It is understood that most of the substandard products for internal wiring diameter is too small. National standards for the performance of the internal wiring, lighting products within the wiring conductor cross-sectional area shall not be less than 0.4 mm2. In this test, the minimum cross-sectional area of the interior wiring conductor of individual lamps and lanterns is only 0.1 mm2. The spot checks of lamp products, there are 7 batches of products exist in this problem, accounting for 17.5% of the total.
