LCD Backlight

Anyone know how many LCD backlight fluorescent bulbs I can drive from one inverter? We have ~18lbs. of fluorescent backlights (ebay) that my friend bought, but no inverters.

I read that they take 500-800VAC, so I'm hoping to salvage some old inverters to use. Do the fluorescent bulbs need a specific voltage, or would any inverter work?

Different bulbs will require different strike voltage, operating voltage, and different currents. Don't assume that the inverters you have will drive any particular bulb.
