Bought two packs. The first fell out quickly, about 6 weeks of use. The ends of the tube were blackened, as can be seen on a conventional fluorescent lamp after many years of use. Replaced with a second bulb, hope for a better result. They are quite dim compared to my other brand lights. If the lights were close this would be a problem. Fortunately, they are on different walls. Overall, I do not recommend this product and will purchase another brand of bulb to be prepared for failure of the previous one. UPDATE: The second bulb died within a few days of installation. This is 0 out of 2, the rating has been changed to one star.
