I have had to return bulbs years ago. Bought wrong size before for a fish aquarium and a couple times with a mvb that wouldn't last more then a day or two. Also have returned mvb online for the same reason as the others.Since bulbs don't have little hour counters on them then who is to know? If I brought it back a week later I could have put 168 hours on it! Imagine clerks doing math to see if you went beyond a preset hour limit. I would buy bulbs just to take back to watch that show!!!!
I probably was getting the ones all the dishonest people are returning.
