Query: too expensive to be disposable

Used this lamp maybe for 150 hours max. Then it would not turn on any more. So thought must be the bulb. Was that not supposed to last for 10 0000 hours? I am an older lady with no kids in the house so no rough handling here. Bought a new bulb still does not work. So must be the ballast as other reviewers write.I can not believe that such an expensive product can not be repaired? Dr. Ott first you make us spend all this money to buy your lamp (promising heaven to our eyes) and then you contribute to unnecessarily producing more garbage to this already suffocating earth? Not ethical!!!! My advice "don't buy this lamp"!
