Welp that's all folks. Bulb burned out again, this time I managed to get around 3700hrs in economy mode. Not too shabby but the other one lasted longer. New one has been ordered. You don't realize how much you miss your pj until the lamp burns out and you have to suffer 4 or 5 days until the new one is shipped to you. It's torment
By the way, is there no way to clean the filter in this unit? I see nothing on the pj that's detachable other than the lamp compartment.
