Didn't know these were halogen bulbs and wouldn't have bought them if I did. But I decided to give them a try and I'm so glad I did. The main thing I found is how bright they are. I only like GE bulbs and would like to have the foresight to buy as many as possible before they run out. Those were the only ones I saw on Revain. I wanted 75 watt bulbs and was very glad they were even brighter. I have a large lamp with a dark shade and it never seems to give out enough light. But once I replaced a regular 60 watt GE lightbulb with this one, what an amazing difference. I was worried it's halogen because I've heard so many fire stories. As you know, the Windsor Castle fire in 1992 when a halogen lamp set fire to a tapestry comes to mind, and we all know what happened next. But they must have improved the technology because while this design gets hot, it doesn't seem to get as hot as a regular incandescent bulb. So far I am very satisfied and plan to buy more. I thought the price was right and they were delivered quickly and well packaged. I highly recommend them.
