我有一个1980s的T12 /20W国产灯管在老家，现在暂时没办法拍图片，南京牌，现在整套灯具仍然可以正常使用，连启辉器都没换过 ，使用的也比较少
I have a 1980s T12 /20W domestic lamp tube in my hometown. Now I can't take pictures for the time being. Nanjing brand. Now the whole set of lamps can still be used normally. I haven't even changed the starter , and I use it less.
