Which 12 Volt 5W LED lamp requires which 12 Volt LED transformer?
12 volt AC/DC (←which one?) LED spotlights require a transformer that generates direct current and therefore cannot be connected to a 12 volt halogen transformer (but this depends on the number of 12 volt 5W LED bulbs). I would like to purchase a 12 volt ?→ AC/DC ←? LED transformer for my three 12 volt 5W LED spotlights.
I'm confused by the specifications for AC current, DC current, and AC/DC current. The LED spotlight doesn't mention AC/DC 😖. Which one is suitable for which LED transformer?
Please explain clearly (I'm not an electrical expert :-), thanks. Perhaps you can suggest a 12-volt LED transformer for 3x 5W LED spots?! The plasterboard opening is 80mm in diameter.

I assume that these bulbs come clear with alternating current. first, it is a G 5.3 replacement and secondly, if it is a direct current illuminant, a polarity would have to be recognizable somewhere, i.e. at least the positive pole would be characterized as such.
Thank you.
A transformer cannot generate direct current. Transformers work exclusively with AC voltage.
AC = Alternating Current = AC
DC = Direct Current = DC
AC/DC = can both
If the bulb is not explicitly AC or AC/DC, it is to be assumed that it is DC. LEDs basically only work with direct current. For AC power capability, the LED requires a pre-connected rectifier.
So you don’t need a transformer. Trafos have not been used for ever since, because they are far too inefficient. You need a 12V EVG (= electronic ballast) with appropriate power. Which depends on the intended use and the luminaire.
a hit can already generate current
He can’t. A transformer only works with alternating current.
I am very happy
This is called KVG (conventional ballast). And what exactly does this have to do with the original statement? Right, nothing. This is because the DC voltage is generated by the rectifier and not by the transformer.
in the housing of the transformer is often the rectifier in it and a lamp can be connected by this. MONITORING
And that’s wrong. A transformer cannot generate direct current. How many more?
I told you
And at the entrance? How dare you? Apart from that, it doesn’t change the fact that the transformer works only with alternating current.
only one rectifier must be
