4 khz inverter heating up
I just assembled my new blade today and tested it out with just the electronics I ordered which I'll put into a custom hilt soon. I have the 4 khz inverter and dual 9v adapter both bought from here. The blade is clean and bright but the inverter heats up hot, even when the blade is off. Is that normal? Are dual 9v a problem? I'd like to get my blade as bright as possible, bright as an MR FX if possible. I'm just a little concerned about things overheating. Would 8 AAA's be better? Thanks for any info.
