I plan on getting 2 tube only kits of CCFL and i need to know if all CCFL use the same connecters and if it will work with the inverter i currently have or will i have to get a different inverter for the CCFL.

They should be but sadly they're not it depends on the components inside some may give you brighter lights and some dimmer but on the other hand the dimmer ones will make your ccfl's last longer

i know vantec ccfl work with sunbeam inverters. but its best to buy the same company inverters with same company tubes.

all is a big word, but i've mix and matched inverters and ccfl tube i've gotten from 3 or 4 different online retailers and haven't had any problem what so ever.
