Replacing the old 6-10 inch tall Canning bulbs was an easy job, especially their brightness and ease of installation. Highly efficient, power-saving and brightening lights. It works great in the shower and outside as they are waterproof. They are tightly closed by seams, quality and ergonomic lighting. The only thing I took off a star for is that they are a bit softer than 5000k in color, more like 4000k which is totally fine!
