Warning Not for electric laity

Have the cheap LED lamps purchased as they were reasonably priced in relation to the offers at the hardware store.
Unfortunately, a lamp connection designation was wrong !! So which one connects the lamp incorrectly if one of the
Holds designation. These things I have written to the manufacturer, but I was not answered.
In addition, you can only get 1quadrat line through the cable gland. This I had to rebuild because with me everywhere
1.5 square are installed line.
If you should try to connect the lamp on the wall is inevitable, a nervous breakdown, very small junction box and a seal that does not really fit.
After all these hurdles were taken to do the lamps they are.
