Hardly radiates upward, much to the side .will not that you have to buy another product Have 48 SMD on the side and only 6 counted up (would then be a total of 54, stated: 48)) Replaces 40W incandescent bulb. Indicated 3.5 watts // remeasured 3.0 watts. So can not confirm what is written in many recessions, he needs about 9 watts. Very nice cuddly small and compact.
