More powerful than compact fluorescent and apparently having a longer service life (what could be more unbearable than wait for the bulb "heats" pro-gres-sively as soon as it is no longer new), I still can not find the quality incandescent lamps but hey it's good for the planet and for the electricity bill. Instead I chose "daylight white" we should rather rename "white morgue." Certainly it illuminates but the light is worse than that of neon. Halloween-death effect guaranteed living in an all-white bathroom (like mine) when you look in a mirror. Do not go see right away ... it is the light that gives you that pale complexion ;-) engineers they will one day find a compromise between "daylight-morgue" and "hot-where light are my glasses and my torch "? A question I leave to your sagacity.
