- The good thing is that they function properly
- The lamp holders often go in relatively heavy and make this an unhealthy noise. I expect that they will break the next relamping. But that's a Mutmasung and therefore not so hard to be weighted.
- The cables do not look very heat resistant, so I would not turn in there Halogener.
- The socket itself is from "normal" plastic. For other it is made of ceramic and weighs three times.
- The cable cross-section is 0.75 mm² with standard not a high Flexible cable, but stranded.
A little tip on recreational electrician: Use ferrules when you absolutely want to use luster terminals. Someone wants what I can treat the WAGO, 222-413 / VE00-050 recommend connecting terminals that are very pleasant and safe to install by their orange caps. Where you do not need wire end ferrules, as they are approved for single core and mehrdrätige cable.
Conclusion: Lights sufficient durability cheaper for LED, and it gets only when dranlötet the cable directly.
