The output connectors are 3-pin and completely parallel, but there are as many as 6 wires (they are connected in the plug), the 4th pin of the plug is not connected anywhere.

These were sold by 1 piece per hand, the price soared from the second, although when compared with local ones, the full price is not bad. Finally they started coming. It has not yet been possible to disassemble it – the case walks slightly, but does not want to be pulled together. Length including connectors 18-19cm. Outwardly very Came in 3-4 weeks. Of the 3 pieces, one turned out to be efficient, the rest had poor contact with one of the power wires. upd: I dismantled one thing, it turned out without serious damage – I knocked with a screwdriver with a fairly wide slot: They were partially tracked to https://jiji.com.et/55-flats-shoes the borders of our homeland (which is funny, one of the intermediate points was Luxembourg), but in our country they were not even assigned a local mail track.

two groups of 3 LEDs, each with a 15 Ohm resistor, from 4.9V to 1.9 drops on the resistor, 3V on the diode, mounted on an aluminum plate. The power is close to the declared 1.2W ("power 1.2A" from the seller – probably a typo).
