Skeptical at first, I order a single bulb to make sure it was returning well in my bathroom cabinet, and if it was strong enough. Result: Not only does it fit perfectly, but in addition it perfectly illuminates for a ridiculous consumption !!! In addition, with its tone "daylight" is ideal for illuminating a tall bathroom mirror. I still have two halogen bulbs, but I will not soon replace them with a new order of 2 LED bulbs this time!
