"Todd" at light your reptiles puts many layers of card board wrap on the bulbs. He doesnt even cheat and preinstall them in the fixtures. I have also ordered "ultrasuns" T5HO from discount sites, they also arrived undamaged with "standard" packaging.
I ordered Reptisun T5HO bulbs from Amazon and had them shipped to Korea. All arrived perfectly fine without any issues. That was just my experience though - I can't speak for the packaging of other retailers.
