欧洲灯具ERP指令 (EU) 2019/2020，求助
请问各位。按照欧盟指令(EU) 2019/2020。如果5m的灯条，我们国内的第三方实验室灯条测试都是测50cm的。
那测50cm能不能代替整个5m长的灯条呢？
那请问5m长的灯条与50cm长的灯条，流明相差有多少呀？
For light sources with linear geometry which are scalable but of very long length, such as LED strips or strings, verification testing of market surveillance authorities shall consider a length of 50 cm, or, if the light source is not scalable there, the nearest value to 50 cm. The light source manufacturer or importer shall indicate which separate control gear is suitable for this length.
按指令要求做应当不会错的
