costs much more
-Quecksilber Is problematic in disposal
durations are forever until they light
-Cold and artificial light
-Customize in any version because too bulky
Now a new generation of energy-saving lamps seems to emerge that overcomes almost all the disadvantages.
The lamp is bright rapidly after switching. The 12 W correspond to approximately a 60 watt light bulb. Personally alledings not sufficient for the lighting of an entire room. Range is thus rather as the bedside lamps range
The size of the bulb is roughly equivalent to that of a normal light bulb, thus also fits in old lamps.
The light is .... well ... not really light bulb .... but you will probably have to get used to it in the future
And that mercury is small and contained in the attached lamp.
For long-term experience, I can not say anything that I do not reach 15,000 operating hours within a month in which I have to give the review ;-)
