Have the Mailux in our hallway lighting triple - ceiling lights used where previously G9 Halogenbirnchen with 25 watts of power were installed - ie: The Mailux LEDs are as bright as the halogen lamps in my feeling, the light color is warm white with a yellowish tinge; you can tell the difference but to LEDs with 3000K, which I in the kitchen have as reflectors GU10 lamps - they give a little "cooler" light than this; but is pleasant as corridor lighting and could also serve as a living room or bedroom lighting. In the workspace I prefer rather a bit harder light with more power or more lumens. The best part is, however, that the consumption of the same brightness place at a total of 400 W (when all the lights are turned on) is only around 50 watts - because one has not even equal a bad ecological / economic conscience, if one forgets time, immediately turn off again when it is no longer necessary. I can not say anything yet about the life, as they are only installed fresh - if the lifetime specification but true, they are me possibly even survive - otherwise I will contact you again. Seen from my current experience here these lamps are really recommended; in particular agrees the price-performance ratio!
