So far, I used 3 in ceiling spotlights in the kitchen instead of this LED light bulb energy saving E27-R63 Reflector Lamp "Lightway 2700K MD 12366" of Hofer (in Germany ALDI): Price 4.99, 535 lumens, 11W, official life of 8000 hours, 1300 hours real life, light color 2700K. This LED-E27-R63 reflector lamps has the following data: Price 14,00 incl. Shipping to Austria, 520 lumens, 7 W (measured in real terms even 6.84W), official life 19995 h according packaging, real life is generally more likely to accept significantly higher in LED bulbs, which means I think the official life has probably given more serious caution. Light color 3000K, D = 62.7mm, L = 105.5 mm. Because of the higher order multiples lifetime and better light efficiency of 74.3 instead of 48.6 lumens / watt this LED-E27-R63 bulbs per year costs incl. Current 2000 h (normalized to 720 lumens) 5.43 compared with 7 , 59 at the short-lived lamps of Hofer-Lightway. I have no more economical in May 2013 E27-R63 bulbs from 520 lumens max. 108mm length found. The light color 3000K is slightly colder than the formerly used me to warm 2700K. However, the difference is so small that you can use LED bulbs with 3000K readily in the same room with 2700K light sources. 3000K acts around a track brighter.
Disadvantages: Probably has broken through the transport in a delivered of 2 LED lamps, a ca. 10x3mm long cylindrical part, the "rattling" in motion and a little is visible on the light surface. However, the bulb is not broken and is lit, the detached part of the bulbs is also almost not visible.
Since the function is not affected by the detached part, I rate this LED R63 bulbs still the highest rating 5 stars because I, despite intensive Market Research no economical R63 Competition lamps from 520 lumens max. 108mm length is known. Based on this comparative research was of lamps Total incl. Shipping to Austria. The manufacturer should, however, take action against the loosening of parts in the lamps and / or choose a softer transport packaging.
