It is grossly inferior to the earliest Philips Ultinon ones, which worked really well in a fair number of lamps, including a lot of the ones with fresnel optics. Philips discontinued those, and replaced them with a different design a little like the Sylvania Zevo Y-frame items. These worked less well, and in fewer lamps. Then they discontinued those and brought out three different new designs, including the ones you've linked, which…work less well, and in fewer lamps.
