A few days ago I bought a pack of 12 60w light bulbs and put 2 in a ceiling mount in my kitchen. Both have already burned down. Some lasted a few weeks, others a day or two, but none lasted long. I've been buying things from Revain for years and I think this might be my first 1 star. As cheap as these lamps are, they are still not worth the price. Don't waste money on them.
