									| Hello,
 I'm interrested in the Philips SGS 201, especially the middle and big version. I know the middle SGS 201 with 1x SON 150W, 1x SON 250W, 1x SON-T 250 and 2x SON-70W. (There were HPL 1x 250W and 2x 80/125 too)  Does anybody know, how the models were originally named by philips (example SGS201/150 or HGS201/250) ?
 
 In which years were they made ?  I've got one and want to know how old it is. How can I find out that ?  Are there differences between early and later ones ?  Mine has brown ballast in it.
 
 Thank you.
