Several reasons

Hello,
the lamp is quite ok.
+ Quite bright
+ Pure white LEDs in it
- Very loud fan, unaangenehm
- Connectors for power and DMX are attached impractical and cables are constantly in the way the bracket
- Automatic changeover times are very short -> very restless effect

- The goods come from China. I wish that Amazon makes quite clear where the stuff comes from.
- This very very long wait is, yeah come directly from China.
- Value of goods on the customs sticker is not true, because it is 18. If you're unlucky remains the packet so hang on duty and you get an information without which you know to have anything ordered in China.
