The R7S 118mm fit exactly into our uplight. She donates a pleasant background illumination in our living room. The brilliance I would not compare with a 150 W lamp, rather with a 60 W incandescent lamp what our purpose also completely sufficient only to huge energy savings Imagine. Super light, full buy recommendation. One star deduction there was for 180 degrees viewing angle of the lower level is not as illuminating as I would have wished, is probably z.Zt technically solve different :-)
