Brian - once again you are the voice of reason. I am just going to just buy the bi-pin lamps and the ones out of the stand-ups will be stored for use in other beds when they need changing 600 hours from now. The RDC ones are too long and there is no point in changing the holders for beds I don't plan on having for more than two more busy seasons. I just hate storing lamps, it really eats up my space in my basement.
Thanks all!
