The lighting performance I can not say anything yet. I have been shaken vigorously before installation. Have the radiator (2x30W, 1x20W) received just before the weekend. The idea with the connected cable ends (even amongst many other suppliers of similar flood), I found very modest when ordering. Why an additional connection socket when the machine has a spacious yet? In the recessions I had read, that can be the quite large and spacious switch boxes convert to direct connection relatively easy. After examining the protruding cable ends and open the switch boxes of floodlights I was to say the least somewhat frightened. In all three floodlights were different "connection cable" (if this can be called so) turn, two different types of cable designation is not recognized, all three stranded and not "with rigid internal conductor" (with 1.5 mm2, as the manual prescribes meant is likely to wire). As regards their type was at least one type is not suitable for permanent outdoor use (not even sure H05RN-F, of course, not least NYY). The miracles continued. The switch box the cables were attached (with two floodlights) with two crimp whose plastic insulations all damaged (open isolation!) Were. The cable ends could be drawn from the terminals without effort. Was obvious that these were mounted crimp with unsuitable tools. In a flood, the cable had been additionally soldered improperly in the spring clips before inserting. In the third floodlights total 5 spring clips have been processed, three improperly, two correctly. The well had been repaired before and had another cable (simply rubber cable). To make the disaster complete, I realized that the LED transformers ("LED Drivers") are bonded to silicon massively at the terminal housing cover, quite arbitrarily, sometimes with the top inside, then you can at least recognize the performance data, times Conversely. Since the low-voltage supply lines, either, both or at least one connected with short wires directly to the LED unit, the lid can be hard to lose weight, without disconnecting the wires. Botch on whole level. Too bad, because the housing design seems quite useful. What to do, was the question. I have decided, as far as possible, properly electrically equip or to be equipped so that they can be used without risk, simply because I need these things. I can only state that, in the three radiators, which I bought, devices were delivered from my point of view with respect to certainly not meet the required safety guidelines. The manuals contain all spotlights the way though somewhere the words "CE", but no declaration of conformity, which would be mandatory for a marketing authorization in the EC. Further, it seems like a joke, if required in the operating instructions of the installation of an upstream residual current circuit breaker. Which, although always recommended, just outside, but not there to protect the failures of suppliers. Overall, I can at least only advise the acquisition of the radiator units this provider. As well as the favorable price or not any great lighting effects help. Who wants to and still accept this at your own risk, the homework of the supplier.
