Ordered for a friend the 2 LED tubes, unfortunately it was the wrong size (120cm) - he needed 150cm - he gave the package is simply the package delivery boy again and I had the company contact because I could not comply with the return formalities - the supplier sent me without hesitation for my friend the right size to his address and on top of that they did not request the 7, -Euro charge who geskostet the longer tubes - the LED lights are projecting bright and shine now in a kebab shop with a lot of power savings - will definitely order again from this company
