My impression is not quite as bright as the light bulbs of the specified wattage comparison. Save Super suitable for power even reach full brightness immediately after switching on. Supplement November 2014: after less than half a year operation broke down the lamp last weekend. How I can see upon reading the reviews, I'm not the only one this has happened to. On the other hand, seem to many to be satisfied (or not only know how to work a review?). My personal conclusion: who needs more such lamps, should take into account shrinkage. Those who buy only one, gets involved in a lottery.
