Result: today, on 11.18.2014, the first lamp broke (first flicker, then were
2 LED segments black, then another 2), after the lamp went out completely.
Calculated uptime in above. Period: under 400 h, ie 2% of the advertised "average life".
Even a light bulb of conventional design will last longer.
Absolutely unakzektable life, therefore depreciation on a star.
Addendum 22.11.2014: 2nd lamp the same phenomenon: flickering, 1 LED segment turned black,
Luminosity can rapidly after, lamp defective.
