Have the air for several months in uplight in the living room in use. It's the perfect energy-saving lamp. No flickering when turning, once with about 80% brightness because, after about 1 minute reaches the final brightness. How to describe the color of this lamp as a cold and frosty, me remains a mystery. The light is almost exactly that of a 100-watt light bulb. Both color, as well as the forth light output. I bet the critical recession refers to the "Daylight" version of this lamp. This has a daylight-like, very bright and cold light, which wikt uncomfortable in the living room. But this warmton variant donates a great and warm light. By the way: I have other Philips Energeisperlampen in spiral shape since sometimes more than 3 years of service: So far, all these lamps perfectly, even in continuous operation. Still no defect and no damage or dents. You are to me really too expensive, but my experience with cheaper versions were previously rather very streaky. Therefore high for this product both thumbs! PS: The lamp is not dimmable if the someone is interested.
