Very good LED spot after the first impression

Supplied as a small package arrived quickly enough packaged, nothing broken.
A little confused, I was through the identification of the spots. On the box of any technical data are given! Cool white various boxes or warm white, but nothing marked. This can be found but fortunately in very tiny letters on the MR16 socket. And there is clearly "AC12V"! And in fact, they remain alight without flicker in AC transformer, provided he can cope with the low load when turning. It helps most when a normal halogen spots at the light remains in it.
Despite the low beam angle creates a very balanced beam, rather than a strong focusing as with other models. A very pleasant warm white light. They are a little brighter than other Lumira LED with 380lm, which are in use for 2 years. Let's see how well they hold.
First of a strong buy recommendation - I'll order a few more.
