Yesterday I've seen this new zumtobel LED fixture in a LIDL store.
The store was quite new (about 3years) and it was fitted with the same type of zumtobel fittings but with T5 49W lamps, now they are already renovating the store and changing all the fittings with these!
A part of the wasting of quite new fixtures, I'm impressed from the efficiency of these new LED fixtures: 136lm/W, 38.3W of power consumption for 5200lm at 4000k and a CRI >80. The light quality is indistinguishable from the standard 840 trisphosphor fluorescent lamps. The lumen maintenance should also be good with 90% @ 50000hr.
