have a question on wiring an LED (backlit) mirror.
So we purchased a LED backlit mirror and I started prepping to wire it to the wall, planning to hardwire it. The mirror came with a plug and recommendation to cut the plug and use corresponding wires to hardwire.
The way it works: line voltage comes in, goes to LED driver that transforms that to 12V that is connected to LED strips around the backing of the mirror.
This is how it was wired out of the box. See the diagram next to the ports. So:
- Unless I'm missing something here, Hot(Line) wire is connected to where Neutral is supposed to be and Neutral is connected to where Line is supposed to be - reversed polarity on that connection.
- The mirror actually works - don't know if that's normal for these LED drivers to work with reverse polarity connected.
- I checked the output on the other side - it outputs 12V DC with the correct polarity as depicted on the diagram.
- I'm guessing this was mis-wired at the factory. We purchased 2 of these with different orders and they came same way, so I guess there's also a chance that this was a bad batch of LED drivers that the manufacturer knew to connect like this.
Manufacturer customer support is not helpful.
- First let me know if I'm understanding this wrong.
- Is it normal for LED drivers to still work when reverse polarity connected?
- Would it make sense to attempt connecting it the right way and what are the risks of doing so?
I'll need to make this work with this type of mirror as we don't have much alternatives - seems like I have following options:
- a) Hardwire into the wall the way this is now, with what seems to me like reverse polarity.
- b) Try to wire this properly and, if works - hardwire properly in the wall.
- c) Purchase another LED driver with good reviews and wire it according to the specification. What would you do?
