The new generation of bulbs

Looking for a new bulb after the previous had passed the bucket, I inquired and have wanted to try it, and I'm not disappointed.
In my view disproportionate to the "old" lighting technologies, LED bulbs will have only advantages:

- Ridiculous consumption (7W in this case).
- Powerful lighting (indeed equivalent to 75W announced).
- No heat (it was time ...).
- Instant maximum lighting (no warm-up period).
- Incomparable life (about five times).

It is suitable for illuminating a piece of approx. 10 m², that is to say a room: it is perfect for a bedside lamp. The emitted light is "warm white" (read classic but nice and soft yellow, not white light).
Note that a more powerful model exists, but it is in my book in parts, the surface is more important, as the living room.
