Replacement bulbs for coralife 2x 65w pc fixtures

[irene]

Does anyone know if 55w pc's generally work in these fixtures?  I bought 2 55w pc's and they didn't seem compatible, they they just burned really bright for a few seconds then turned off.  Maybe I just didn't get good quality bulbs though?

Does anyone besides coralife make 65w straight pin pc's?  Looking for a less expensive replacement.

Thanks,

Irene
