Surely this would be true for the PL-L bulbs aswell? I am not saying the larger bulbs are better (their bulkiness is a downside to them). But I would think that the PL-L's whilst better overall, might not put out quite as much usable light as you think, as half of the bulb is facing a reflector (Unless you hang them vertically, which is easier to do than with the big 250's).
