I have both a table and a floor model- they advertise the bulbs will last 10,000 hours. They are fabulous. I even use mine for reading...and tweezing those pesky hairs that show up on the ...ahem...face. lol. if you do decide on an OTT lamp, they are often on sale for 40 to 50% off. No way would I pay full price for one- toooooo expensive.
