Rectifying AC->DC at one point for all lights instead of at/in each light should be more efficient and reliable (one to fail instead of 'n', the LEDs themselves being super long lasting). That being said, the prices of drivers (even 120V -> low voltage DC for LEDs, as is the case inside individual Edison-base LED bulbs) is so low now as to be absurd. | |

I asked the manufacturer of these lights about using an AC supply. Their response: "Our lights must run on a DC transformer. Using an AC transformer will end up burning out the LED boards and cause failure." | |

| Dec 9, 2020 at 4:03 | comment | added | RayW | Hi. These lights will sit atop 2.5" square aluminum posts so my options are limited. I've found only eight lights that will fit. Five of them are 12VDC and another is only listed as 12V. Of course, the ones we like are among the 12VDC options. | |
