The spots I have used in the past years were from home depot/Kmart/Walmart (have a mix).I did purchase several of the GR spots that are clearanced a few months ago. I only plugged them in the dark in the bathroom to test them out. They seem just as bright as any others I have purchased. I love the spots, they let off a lot of light and project well for near or far. The only differences I can really tell between spots from different retailers are in the cords. Some have a cheaper thin indoor type cord with 2 prongs. Others have a thicker outdoor type cord with 2-3prongs...they are all supposed to be outdoor use though. The GR ones I got have a thick cord with 2 prongs. Hope that is helpful. I haven't used them in a display yet
Well, I will have to let you know when the next Friends and Family wine sale starts! My husband works for Treasury Wine Estates, they own a ton of great brands like Beringer, Chateau St Jean, Stags' Leap, Penfolds. Next sale is usually in early November and shipping is included. Gotta help keep my fellow winos fully stocked!
