What would happen if...

Hmm, interesting. I don't know what kind of ballast - it's a Coralife Aqualight fixture, so whatever they use in those...

Heh, amusing...

I actually looked in my two coralife 2x65's today - 3 of the bulbs are 55w'ers. All have been like that for >1yr.

You can also get adapters so you can adapt the bulbs from one pin style to the other.

the coralife aqualights use electronic ballast so go for it..... trust me it will work.

Andy, where did you get the pin convertor? I'm looking to convert some square to straight pins without having to rip out the previous.

It worked for me. I have tried it and used it for extended period of time. However, if I remember correct, it will only produce ~63watt equivalent output. If the bulb is spec at 55watt, it will be overdriven a bit and give off a little more heat. Otherwise, it will work perfectly fine.

On the overdriving topic, there are numerous articles on the internet about overdrive PC lights. Mostly about doubling the power source to the bulb by connect the ballast for two bulbs into one. From what I understood, the bulbs with double input will not double in output. I think it was something like 1.5X the output. Again, the bulb will heat up even more. Safety hazard for sure. I won't do it, but I think it is good to know.

BTW, pin adaptor can be found on ebay: http://cgi.ebay.ca/Power-Compact-Flu...QQcmdZViewItem

Yeah, I've been using my old 55 watt for several days now, no problems. It's a good temporary solution...
