A small drawback, the cable feed openings, which are easy to break out only on the side - for the bottom you need a drill, or one breaks perhaps the housing. That hurts the lamp not constituting a separate, self-contained and waterproof unit, thus not even be repaired.
Also one must not forget at Weglampen that the lamps emit only upwards. This means that for example, on house walls look great and distribute their light by reflection, but in an open area bedazzle only one who passes by it. There are therefore more "Wegmarkierungslampen". ;)
We were in some LEDs 6 lamps of 26 tested defective (30 ordered), the rest is working properly. Defective lights go now for Exchange, so you should always order a few more lights than you need - if the electrician empty-handed will have to deduct again, because you have no lighting in reserve, annoys you otherwise In addition, it makes sense. to have some of the things in stock, if after a few years break in operation which, and the series is no longer available, if possible.
All in all, I would buy the product again. I'll update the review after some time again when the exchange has been completed and the lights were a few months in operation.
Update March 2015: The conversion was carried out by the provider easily and very quickly. Since there were no further problems and we look forward every day on our lights. :)
