Light color
I feel a little colder than usual at 2700 K; but may also be because two of the lamps next to each other (distance about 30 cm) are operated
Power
6 Watt as the equivalent of a 40 watt bulb; in my opinion this is fully achieved or exceeded
Durability
Nominal specify 100,000 operations and 20 years. The indication of the number of switching operations is far higher than comparable lamps of competitors (only 15,000 or 20,000 switching operations are often specified).
If from the long-term use of new knowledge, I would complete the report in any case.
Others
The light source is immediately bright after power on. After switching off, this lamp, like most LED bulbs lit for a fraction of a second, slightly.
The lamp can be dimmed. However, we do not use this feature.
A slight hum can I perceive. Since the lamps are used in the bathroom, this does not interfere. In other areas, however, the noise could possibly be distracting.
Price
Compared to other bulbs, perhaps because of the small construction and vglw. high performance very expensive. In local retailers I have spent almost 13 euros.
Conclusion
Small lamp (length 89 mm, diameter 43 mm) with high power (6 watts = 40 watts). The disadvantages of energy saving lamps (mercury and long lead time) are completely eliminated. The price is very high for LED lamps.
I can recommend the lamps definitely.
