I purchased these lights for our product, 24V, LED, 12.7mm. The lights are listed under UL and arrived as the drawings and specifications outlines. Product was also well packaged. I dissected one to look at the construction and quality and I was pleased with the construction. I also have one operating 24/7 for two weeks now, no noticeable heat, it is bright, and running strong. I am verry happy with this product and will purchase again.
