The originals of these were very good - when they used a pearlised outer envelope. But note the picture in your link shows a clear enveloped capsule bulb in a clear outer envelope. Unfortunately, this leads to them producing a 'harsh' light with sharp shadows. Which is precisely why pearlisation of the envelope of incandescent bulbs, was introduced in the first place. I have wall lights in my lounge, which use R50 reflectors. They shine up onto the ceiling, and used to produce a nice diffuse light from the pearl-fronted bulb envelope. But now, they are only available with a clear-fronted envelope, and the consequence of this is that the blue glass shade which used to glow nice and evenly, now has light and dark stripes in it, and the light that falls on the ceiling, is an image of the filament. I also have a four lamp fixture here in the computer room, which uses the same bulb type. The room used to be nice and bright all over. Now, with clear fronted bulbs fitted, it doesn't matter where you point each individual spot-lamp, the room is a sea of shadows and pools of light. Gawd, how I hate all this eco-bollox nonsense ... >:-(
