I have the light bulb filaments with now two to three months in use and am very satisfied. I currently have about 40 pieces in use. It's fun the old 40-watt bulbs to replace these two watts and having to accept no noticeable loss of luminosity. The price I think is okay. Every now and then there is the 5-pack instead of 29 for 20 euros, but the price is really good. Positives: - Economical (per watt 110 lumens!) - Immediately turning on full brightness (with energy saving lamps you wait so once; very interesting, if you want to down a steep staircase and wait and see or have the light needed only briefly). - No real development of heat (not necessarily important but interesting; although, no longer burn at very young children who could come to the light bulb that are). Negatives: - This light bulb has now only two filaments. This can lead to more or less shadow effects. I have about 40 pieces felt this with a light bulb as unpleasant and this light bulb banned in a lamp, in which I do not notice that. I would possibly prefer a light bulb with three filaments, here would not make this shadow effects. - The luminosity varies ever and again is this to me of 40 bulbs noticed at a disturbing but you always have the possibility of using even those light bulbs. To this end, following the declaration by the dealer: "As to your question of the color of light, it behaves so that the specified light color of 2700K has a tolerance of 10% and may vary around this value up or down but these are maximum values and usually is the deviation. hardly recognizable. The light color will not change over the course of time. The luminosity is central to all LEDs from the lifetime. This is after 6000 hours of continuous operation at least another 80%. After the test of TÜV Rheinland, on average 88%. " Notes: What makes me a bit suspicious is that hardly any service provider supports this type of lamps. Aldi and Lidl or trade houses do not know these filaments technique or not offer them at least. Only in Bauhaus I have this type lamps found - strange. We want to use the power consumption makes sense - how can the great houses will still sell 40 watt bulbs - I do not understand. Use: Dining table: 3x2W => sufficient (pleasant; should also not blinded). Nursery: 6x2W => superbright (pleasantly) Outdoor light doorstep: 2x4W => sufficiently Hallway: below 8x2W 6x2W above => superbright (pleasantly) Conclusion: I love to save and this lamps Likes Hammer! But please do not fall for cheap products => For cheap I have no money ;-)
