The walimex Daylight Set 250 delivers a fine diffuse light. Very well suited for portrait photography. I recommend 2 sets, one of which should be equipped with einerer stronger lamp (s gives at Amazon). Quick on - and dismantled, small stowed in the attached bag, what more could you want. Use caution when handling the bulb, do not touch the tube to roll in, otherwise they may break and then you have mercury in the apartment, but that's with all the energy saving light bulbs like this.
From me 5 stars for price, performance and delivery fleet.
