Good replacement for 25W incandescent bulb with an average lifetime

Because of the good reviews, I then decided to use the LED bulb of Müller light. Now I would now briefly discuss the advantages and disadvantages of this LED bulb:

ADVANTAGES:
- The light is (almost) in stock; There are at power although a short "delay" in the not yet full light intensity is available, but this will only take a fraction of a second
- The light fades not because of the matte glass surface
- The bulb has a very large viewing angle, whereby the room is very well lit.
- It can not hear humming or buzzing noise
- Brighter than 25W bulbs (according to packaging is the bulb from the light here is equivalent to a 32W bulb)

DISADVANTAGES:
- Rather average (under) life, sometimes just 1 month (see update below)
- Color temperature rather neutral white (but still pleasant), skin works by some "pale"

UPDATE 08/04/2013:

In less than 4 months a bulb stops working. This is a bit disappointing because LED bulbs are supposed to last longer. The broken bulb will be replaced by the dealer. Two other bulbs of this type (though not quite as old) are still running without any problems.

UPDATE 09/09/2013:

After almost a month, the replacement bulb has gone out in the middle of operation, which is why I have now taken off a star. The other two bulbs of this type are already for 5 months (and hopefully much longer). I will now try the new harvester series of Bioledex as these (according to the data) is better on the color temperature here (2700K) are doing as the LED bulb from Müller-light (3000K) and also more light. In the meantime, I have also tried the LED bulb from Lighting EVER, the white light but is "amplified" by the high light output and is therefore more suitable for workrooms.

UPDATE 24/09/2013:

I have (E14 R50 6.5W 470Lm Warm White LED Spot Bioledex RODER) now in use, and can replace 40W incandescent bulbs (with respect to the light and color temperature) recommend the new harvester series of Bioledex. Two LED bulbs Müller-light running for about 5 1/2 months without problems, another for about 1/2 month also, which I will probably change in the medium term on the Bioledex bulb, since these additionally also offers 3 years warranty.

UPDATE 07/11/2013:

After nearly 6 1/2 months another LED bulb is defective, the specified service life has not yet been reached by far (replacement is then virtually no longer possible). This has 3 LED bulbs this type by 1 to 6 1/2 months, broke down with me. I am now but already a bit disappointed by this LED bulb, since I am apparently not the only one with this problem, especially since I bought the LED bulb by different traders at different times and they all show the same phenomenon. Probably it was saved to the hardware, as Müller-light or the producer has already done (according to articles in electronic forums) with the energy-saving lamps. Currently still running two pears with me, being a 6 1/2 months and the other just under 2 months old. In future I will no longer buy myself the bulb. Because of the rather poor life I pull from another star.

UPDATE 11/13/2013:

I seem to have either bad luck or it really seems to be due to the pears: today another bulb has gone out in the middle of operation, it held about 2 months. Meanwhile, I can not think of a coincidence, since LED bulbs from other manufacturers operate in the same lamp in part for over a year without any problems. Also I noticed today that the "shaking" of the bulb a sound is heard, as if something were loose (probably the board). These things I have noticed all pears this type on a number /, pears of other manufacturers this is me not even noticed. I therefore draw from another star.

UPDATE 04/20/2014:

With a lifetime of less than a year, the last LED bulb has now failed. All other LED bulbs (from other manufacturers) that I use currently, still operate without problems and in some cases even a year longer in use. The lifetime of LED bulbs with me ranged from about a month up to one year, the latter value significantly is still below the promised duration. I therefore draw from another star and would now no longer really recommend the LED bulb.
