Hello, I have a 30 inch coralife lighting fixture with 2 50/50 65 watt bulbs. I heard that you can find them much cheaper online than at a local fish store. And I was curious if I could possibly use these bulbs in my fixture 55 Watt 20.7" 4 Pin Biax - Aquarium Fresh & Saltwater Phosphor: Light Bulbs Etc, Inc. And if I can't does anyone know a cheap place to get replacement bulbs?
If the bulb is not an exact replacement it is sometimes best to just give their tec support a call. Most companies have a toll free #. Just give them your fixture name or bulb # and they should be able to help you.
