Fantastic bulbs!
"I grew up with my grandparents using incandescent infrared bulbs for their arthritis and back pain. Of course I was curious and would try their handheld devices. I found the heat warming and relaxing. This was my first time trying LEDs and I love them. I find the light they emit strong, even, and very relaxing. It's nice that I will be able to use these in the summer when I don't want much heat, and use incandescents in the winter if I want heat. These bulbs are heavy and good quality. The threads are made well. The customer service from this company is incredible. They answered all my questions about a DIY set-up, and I'm very happy I got these for my daughter and myself!"
