These lights have inspired me immediately. The brightness is super with low power consumption (where the performance information is correct, I have not measured by).
Very convincing is especially the light color. I have many so-called "warm white" LED spots, sometimes even tested very much more expensive. But the light color of these spots is absolutely identical with halogen spotlights. In the way I have not found anything else.
The manufacturer does not indicate whether they are dimmable, so I'm assuming that this is not so. That would be the icing because I necessarily need dimmable GU10 LED's.
Durability remains to be seen, but they are still too new. With 40 lamps purchased there after a week no complaints. However, this is not just from other suppliers.
