I use them every day in my online shop to photograph clothes, shoes, antiques, art, you name it. They are packaged very well, give great light and are a good price. I've ordered them many times. I never have to reorder because of a blown bulb. Rather, I have a habit of breaking them by tripping over my rearranged lamps. God, do they ever break into tiny pieces and crumble to dust very quickly. That's why a 2-pack is great. If I run out of a lightbulb, I order a new one so I'm not stranded the next time I break.
