Hi,
I have an OTT light and the bulb has lasted for over a year now, it's a table model that folds over to close.
However, I also bought a table and a floor model of a daylight/natural light type lamp that aren't OTT lights...they work super. I got both for less than one OTT light on sale. I bought mine at Shopko, which is a discount retail store like a Target or Walmart...they do have them at both of them, too. Check them out, same type of light and I love mine.
