Dearest lemmings, I have a prelit Costco tree that changes from warm white to color and several of the lights are out but I cannot for my life find a replacement anywhere. I called Costco/Polygroup (company that made the tree) and they don’t sell replacement led light bulbs but they gave me these specs: LED dual color 3mm Green Base 20MA 1.8-2.4V or 2.8-3.6V. I tried buying a set of lights at Home Depot but they did not fit and my google-fu is failing me.
With an image and that spec then you could most likely source them from AliExpress or eBay. It will however be a lot of work changing the bulbs since I’m fairly certain from that spec that they’re soldered on and thus not made to be replaced in a smooth fashion. Still very much doable but the amount of work involved, and the delivery time for the parts / tools you need and it might be a tough ask to squeeze in before Christmas. I’d probably just buy a new tree then if I end up with some free time repair it and sell it.
