Wolf reduced the number of bulbs in his range hood from 4 to 2. My wife then complained that the light was too dim when cooking, especially in the winter sun. I used these FEIT bulbs to restore the light. The two 800 lumen bulbs work the same as the four 400 lumen bulbs on the old model. I have a happy wife again. Feit onions are only two weeks old. I can't say anything about durability. A disadvantage of LED lamps compared to halogen lamps is their sensitivity to heat. I've had LED bulbs fail prematurely in the past, most likely due to the heat of the oven. I have no information on how well these lamps perform over time. Light bulbs fit perfectly in the space allowed. If anyone is looking to increase the brightness of their GU10 bulbs in the range, these bulbs will help. .
