Chinese LED Flood Lights (Wirings)

I got some LED flood lights (made in China) from Amazon. The wires are coded differently. I did get it to work with 120v AC.

Brown = Black(positive)
Blue = White(neutral)
Yellow = Green(ground)

I assume there is no way to connect these LED flood lights directly to a 12v battery unless using an inverter right?

Brown is live and blue is neutral. Pretty much a standard in the UK. A Euro thing.

LED's don't usually run on line voltage. Many use a driver or power converter.
You'd need to disassemble the fixture to see if there's a hidden driver.

The driver might look like a small circuit board, perhaps the size of a DIMM memory module for a PC if you have ever opened up a desktop PC. Or the driver might consist of a small transformer (may be the shape of a doorbell transformer but probably somewhat smaller). plus some other assorted components including resistors, capacitors, and/or non-light emitting diodes.

The LEDs themselves almost always run on less than five volts each. So any house current application needs a driver.

Sorry, I am not you to have that knowledge or even know what a hidden driver looks like.

I will just stick with buying one made for 12V if I need it in the future.

I have bought some LED's from China made for mains connection, they work well for a short time. Looks like they are made for slighty lower voltage. I have put in a capasitor in series to make a voltage drop, and thos has worked for months. (The capacitor needs a high ohm resitor in parallell to discharge the capasitor when power is off)
Not easy to calculate the right value, but when I see that they give slightly less lightm I have got it right.

Those 12v fixtures are cute. At 12v and running 30 watts they use 2.5 amps of power.
Depending on how long the connecting wiring is you'd need to use decent sized wiring.
#18 at a minimum.
