Not long - ours stopped after 7 months of use - and didn't use it intensively. I wish I had bought a table lamp that uses these hard to find bulbs to start with - wasn't aware at the time. So the first recommendation is not to buy a lamp that uses these bulbs. Second recommendation - try to find a lightbulb that lasts longer, then come back here and let us know which one works!
