Ken,
When I first started, I purchased all the items from domestic retailers. All the parts I received were made in China. I was not aware that there were any domestic mfg's that sold retail. After I purchased from various Ebay sites, I settled on one, mainly because of consistant quality, not the lowest cost.
As you will find out there are 4 different WHITES when it comes to LED's. Everyone has there own preference. My coach has blue accents so in some areas I prefer the cool white, which had a blue tint. For reading & undercabinet I prefer pure white. Warm white has a yellow tint; cold white approaches blue.
I've included a link below that has quite a bit on info on LED's. One of out members even visited an Led factory, while he was on business there.
