LED technology which (finally) convinced!

For a long time LED lamps either weak Funzeln or extremely expensive - not
rarely both. For the first time I'm with these lamps
been really convinced of the opposite!
I have four of these Müller Light R50 5W 105cd warm white for several weeks
in use - which existed at that time for almost 7 Euro at Aldi Süd - Replace
with me in the bedroom conventional 40W R50 bulb.

PRO:
* The angle of radiation is significantly greater than in the Glühobst spots,
but the light is directed forwards.
* Be able to deliver without measured values: The 25W as compared are more
as Conservative! The lights are much brighter than my subjective
40W R40 bulb and would probably even compared with 60W
performing well.
* The color temperature is of course a little cooler than incandescent bulbs,
but even for the bedroom pleasant and not bluish.
* The light does not flicker, as with many other LED lamps
Case
* The lamps work completely silent, hum and hiss like
many others do not can be found here.
* The lamp body is made of ceramic, which allows for better heat dissipation
as the plastic case of many other.
Even after prolonged use, they are not excessively hot, which on
can maximize the life hope.

CONTRA:
* So far, nothing. :-)

Whether the operating time of 20,000 hours is achievable I doubt it, but
the ballast in all 230V LED lamps (just in the fluorescent
Energy-saving lamps) is a general weakness. From the outside can be
not the judge, therefore helps only wait. Ultimately one here
Quality of the components and a low operating temperature, then
the chances of a long lamp life is the greatest.
