I have the small round 3v inverters and have tried atleast two different EL samples both small. I cut one down which helped its intensity, the other i haven't messed with. I have an adjustable power supply and have toyed with voltage to no avail. I agree its gotta be a matter of the EL. I have asked time and time again for a source and just kept getting "go on ebay". With the troubles im having i need an actual source that has worked. A seller that has been used, etc. if someone can send me a sample or even the two cut pieces i need ill gladly pay for them. I have gone through different power sources, tried a different inverter and EL and this project is just falling further behind. The reason im using the 3v inverter is to put everything in the buckle. HELP!
