1、 IEC 61347-2-3 Essay abstract: Fluorescent lamps having high luminous efficacy equipped with electronic ballast having low power consumption is still the first choice among the indoor illuminating products at present. Proper thinning of the tube not only increases luminous efficacy of the lamp but a

The heat deforms the qualified lamp holder and the worse is that the tube glass would mel
