Greetings BadCappers:
In this forum I have see frequent mention of the need for ways to test CCFL Lamps, so I thought I would mention this item;
http://www.ebay.com/itm/1pc-12V-CCFL...item2c6de2cbcd
I just won an eBay auction for one of these at a price of $7.61 with free shipping. This tester uses a 12 Voltios (I hope that is Spanish for Volts) input and, claims to be able to test Lamps up to 700mm in length. I will report further when I receive mine and have tried it .
--Previously I have been using one of these;
http://www.ebay.com/itm/1pc-12V-LCD-...item3381293568
Which is rated to test CCFL Lamps of length 300mm or less, and uses a 12 Volt input. However by using my old Heathkit Linear Power Supply, and cranking her up to 30 Volts or more I have been able to get Lamps of any length to fire. Now, while this is able to show me that the Lamp will fire and whether or not it is beginning to show red from mercury migration, it less than satisfactory because I am not really sure whether I am over volting the lamp or not. Needless to say, I do not leave this cobble rig on for long, as I was pretty sure it could blow at any time. But so far it has served.
--I do most of my Voltage measurements with a Fluke 87V DMM, which is only rated to 1000 Volts, so I am unsure as to what is the best way to measure the Voltage and Current output going from the inverter circuit to a Lamp. If anyone would care to provide advice on this or point to a good posting, I would appreciate it.
