Blitzversand, good price / performance ratio, good packaging. Warning - do not give up hope the same - the energy saving lamp needs some time (at least 5 minutes) until it reaches its maximum brightness - but then it is - above all the neutral white unbeatable light and strong! Beats my conventional 100 Watt lamp (warm white) to lengths! I will replace now all exterior lamps - the burn often long in the driveway and then you can really SAVING! And I personally find the neutral white light so much nicer!
