Depending on the exact noise it may or may not be a problem. Since there are no fans in these units, noises from the lamp are more apparent. What you should be able to hear is the rapid tick-tick-tick of the ignitor as the lamp strikes, then it should change to a sort of buzz/high pitch whine as the arc in the lamp stabilizes.
