macmods adapter - use

Hi, Im using the macmods adapter and have some questions, (Im apologize about my english):

Do someone knows if its ok to connect to 1 tube lcd an inverter designed to feed 2 tubes?

The imac intel inverter its connected to a original 2 tubes lcd, but the macmood includes an Y adapter to use a single tube lcd as replacement, I notice that the one tube lcd I use goes to hot on the bottom (where the tube is placed) and perhaps is cause the inverter doubles the current nedded for the tube.

I dont know to test it, I mean how to measure and compare the original current on the 2 tubes lcd vs the 1 tube replacement lcd.

Thanks a lot
