I'm going to be grabbing up some RGB tube lights soon to add to my kit. I've only ever used 4' tubes but I've seen some comments on B&H from users that wished they'd purchased 2' tubes instead of 4' ones, just due to ease of travel and being able to stick them into more spaces. I could see that being a nice benefit. Anyone else prefer the 2' tubes over the 4' ones? Any major reasons 4' tubes are worth it over the shorter models?
