Review on Outdoor Security Made Easy: 2-Pack Of DC 12V Low Voltage LED Flood Lights For Bright 6500K Daylight White Illumination by Jessie Burgos

I am stumped on the product description after buying 4 of these and mounting them. I didn't fully wire them after seeing the + & - signs on the wires. The product description reads "DC 12V for Power or Battery, low voltage, Great for Battery Work light, Spotlight, Solar powered , Car Boat Lamp DIY. If use it to 110v AC voltage, a 12v transformer needed" I read and read and do not see a clear answer. I had originally searched AMAZON for " 12 VAC Low Voltage Outdoor Flood Lights" when these came up I glanced at the description and ordered them. However, when I mounted them and saw the + & - signs on the wires I paused because in 12v low voltage AC there is no + & - from the 12 VAC transformer. I also know that if they are DC and you hook up DC lights to a 12 V AC transformer the lights will flicker. As far as I know they can't be both AC and DC. So which is it? Are these lights the same as regular 12v low voltage landscape lights or are they DC and made to run from batteries or DC current made from a different kind of transformer that converts AC to DC. I am getting frustrated trying to read and find the answer. This should be a clear cut question and answer.
