I need help finding 55w PC's

[Jack]

Hey,

I was using 2x55w PC's over my refugium but one burnt out and another one got broke by accident. Where can I get cheap replacement bulbs that will be good enough for growing macro?

What should I use meanwhile? I'm using a 20w tube right now and it looks pathetic.

I appreciate all help and suggestions.

Edit* It says on the bulb:

Panasonic
FPL55E67
Made in Japan

Oh, and it's square pin.
