When we did our LED conversion 3 years ago I used an Ebay store that was recommended by members here on the forum as there are many posts with great info on this subject. All the LEDs we purchased were in the 3K spectrum that gave nearly the same warm light produced by the incandescents they replaced and were brighter to boot. No failures to report thus far, purchased a few from US stores where prices were several times higher only to find that these were also made in China. One of my favorite mods as we prefer to camp off the grid.
