I ordered them mainly because of their size. I needed them to fit my existing outdoor lights, specifically the RAB Lighting H101A Landscape Lighting Spotlight. Some bulbs fit fine but the hood, a separate part I also have, a RAB Lighting HH1A H-System hood, does not fit. about it because they hit the glass surface, i.e. they are too long. They fit perfectly (see pictures for a better idea of what I mean). They are pretty bright and do their job well. As another reviewer mentioned, they get hot and I mean really hot and really fast. They give off so much heat that I don't think I'll ever use them indoors in my house. For this purpose I will use an LED or fluorescent configuration instead of a halogen configuration. However, for outdoor landscape lighting, they work great. As for their durability, time will tell. If anything changes as I use them more I will update this review. I hope this was of some help to you, thanks for reading!
