Good fit, warm light, perfectly dimmable and relatively sparingly

Can not complain absolutely. The Osram are beautiful bulbous but quite short, so they fit perfectly into the provided chandelier. They are really bright for 20W (25W are supposed to replace, and can also MMN) and exude a pleasant warm light as I want it in the living room. The dimming is also given wonderful, from light to barely visible glow anything goes.
Since (affordable) LED not seem to be able to combine dimming and warm lighting, currently leads anything past these lights.

For durability, I can only say: I've been using for 3 years Osram Halopin 20W for the G4 base, there's not a gone from broken, unlike no-name lamps that have worked an average of six months ... The surcharge So worth.

But: halogen are sensitive to fat, for example, of the famous "fat fingers". Whoever touches the halogen lamps when installed without gloves or cloth, will not prolong the enjoyment of them.
