LOL GE's endcaps haven't changed much over the years...
Mine were FREE! (only cost was they were a PITA to transport over several months) Even better! LOL but yours were pretty cheap too!
Oh and (gasp, barf, gag) I picked up 3 34w black-etch GE 34w Watt-Misers yesterday. Haven't tested them yet...I know, I know, but they were free, probably work, and they're fine in warm environments on energy-saver ballasts...If I had to buy lamps and pay for them I would get full-wattage ones of course, though...
