just picked up a coralife light fixture 48" 65w 4 pin straight with 2 actinic 2 10000k. 2 bulbs blew out already. i dont know why. 1 actinc 1 10000k. when i went to remove them from the socket, it was like jammed on. then the bulbs seperated completely from the plastic casing"????---anyway where can i find these bulbs where they dont cost an arm and a leg. and anyone know where i can find the legs for this fixture. thanks
