Thank you very much for the answers that you can give me and GREETINGS
good night I fixed in the reflector and it does not have any specification since it came packed without its box I take it 2 photos one of front and the other one of the back here I upload the image
fabi,
If it is safe that the original source was DC 20 volts and we have no more data in the reflector, there is much more to do.
Anyway you can try Dc12 volts, at most would not turn properly, nothing should happen but is to take a watering, which can be greater if you place a reflector of 12 volts power of 20 volts.
At lower DC voltage there is no way that with a fixed load increase the amperage, so this should be less than 7.5 A.
If you do not want to risk the 12-volt supply, try a 12-volt battery and that's it, do not be polarized.
