The strip consists of shorter strips which are soldered under the silicone jacket. That is, alle..ca. 30cm is the brazing strips already solder on it, but in the silicone.
Not necessarily a disadvantage, therefore could be (I have used soeine point) solder properly.
Silicone carefully cut and pull, soldering.
A dimmer I need here, a total of about 24W Strip should have, but the light output is compared with GU10 LEDs rather disappointing.
(With the same electrical performance I light two rooms with ceiling spotlights bright as day, I could not with this strip.)
But when backlit it was good enough, and I do not need a dimmer.
