    Test inverter - what current?

    There is a company called Microsemi that makes inexpensive inverters which are available through Digikey. To see some of these use Google shopping with the query "inverter ccfl" and sort by increasing price. I want to get one of these for testing lamps in displays. But which one? They come with different output current settings and run at different input voltages (5 or 12V). Here is the data sheet for one of them - most of the links from the above search lead to Digikey entries without working data sheet links:

    It appears that the drive current is the key difference between most of these. What would be a good current to use for testing on 17" and up (but probably not too far up, I don't expect it to work on a 50" TV) displays? This will be powered by a scavenged ATX PS, which has both 5V and 12V and plenty of amps for either, so the input voltage isn't going to be critical.

    As an extra added bonus, the datasheet linked above gives the names for some types of CCFL connectors, which at least brings into the realm of possibility the option of ordering adapters from one to the other.

    Oops, just noticed that the prices shown in Google Shopping are not nearly as low as the prices that Digikey actually lists. Anyway, the main question remains - what would be a good drive current to shoot for in a test inverter?
