We always have problems with the lights in our walking freezer until I found these ones... !!!FANTASTIC PRODUCT!!!. In the past the department of agriculture fine us (diferent times) because the lights in the freezer didn't have a protective case, but we need to remove the case due to the fact that ice build in it, the last time the inspector came and try to fine me, I show the endurance of these lights and he actually told me that he will recommend it to other places. I repeat, this is a FANTASTIC PRODUCT.
