John, When calling around you should ask for AquaRays, which is GE's trade name for these bulbs. Also, ask the pet/aquarium stores if they carry/can order the All-Glass-Aquarium 55w replacement bulbs. There are several types so you'll need to tell them you want the 9325K Super Daylight bulb.
but isnt the all glass 8000k i looked on the web site and it said that the ge 9325k comes with the fixtures but then looking at there cp bulbs it says that the 8000k come with all there fixtures ??? well they dont show that they got the 9325k
I have ordered 4 from atlantalightbulbs before and they called me to let me know they only had three in stock. They have a pretty aggresive substitution policy, so I made sure I commented on the orderform that they should notify me before making any substitutions. I ended up taking the 3 bulbs instead of four - it was just nice to get personal communication from a big faceless company like that.
