Unfortunately, high failure rate and problematic order

Meanwhile, I have 20 of these LEDs in use. Although the lights give a good light, so unfortunately there is trouble enough lights at Amazon get to and so far are by no half a year and four have been defective. They have been installed in the hallway, kitchen and study in the use and in different lights.

My personal impression (subjective - without instruments):

Positives:
- Warm light (very close to a halogen lamp)
- No red-yellow-blue cast recognizable
- Brighter than a 35W halogen, but slightly below a 50W
- Little turn-on delay
- Power consumption (there was a repayment from the power supplier)
- Problem-free exchange in case of defects by Amazon
- Design almost identical to a halogen

Negatives:
- From Amazon I could always just a small amount of order (limit per order and customer)
- 4 of 20 have shown in the first months of a defect (have flickering or completely out I-no dimmer)
- Slight turn-on delay
- Angle smaller than in halogen (yes, it is in the description, but I say it anyway)

Conclusion:
After recent price cuts the lamp is recommended. With regard to the quality and the uncertain long-term quality due to the already high failure rate, there are two star deduction.
