Hi ! As we're now preparing for a post prom pool party for our oldest daughter and the other kids in her class the question of having LED-lights that are RGB and can change color came up, as the kids thought that was a great idea. I think it's too late to consider that for this one, but I'd like to check into it for the future. I've seen such lights both in pool stores and on the web. In the regular pool stores they're quite expensive, but cheap ones are often found on the web, usually sold directly from China. Now my question is: are those of reasonable quality or not ? Has anyone on here tested and been able to tell whether it's just cheap junk or if they work ok ? If you change from regular bulbs (we have the 12 V 300 W PAR56 version), do you need to make any changes to the fittings or to the wiring ? Are there any special things that one should check for if one is considering ordering lights online ?
