Very Short Lifespan Bulb!
I have used different brands of 3-way bulbs for many years and all of them have a pretty good lifespan. I purchased these bulbs and was really surprised that they blew out so quickly. Sylvania advertises that these bulbs "last twice as long as the average light bulb" and that they are supposed to last 1200 hours. I always keep track of when I install a bulb in the 3-way lamps in our home because I'm curious at how long they will last as they a bit pricey. I keep the bulbs on the same wattage (50 watts) 99% of the time and have only used the 100 watt feature about twice per year when I clean out the closet, etc. I put these new bulbs in both lamps in my bedroom and they only lasts 2 months and 1 week each (blew out within 2 days of each other). I use the lamps for 4 to 5 hours in the evening - which is a total of 335 hours (67 days x 5 hours per day). This doesn't even come out to a third of what Sylvania advertises as the lasting power of these bulbs. I don't know if I received a bad batch of bulbs or if this is really how long they last. I purchased three sets of each kind of bulbs: Sylvania 50-100-150-Watt and 30-70-100-Watt. Hopefully the other sets of bulbs last longer. If not, then I will have to find a different brand to purchase. Overall, as it stands, I don't know if I could recommend these bulbs to others as they are very short lived bulbs.
