Nice autopsy of one of these darlings! Done without any assistance from Mr. Smashy or a size 10!

Pathetic but it does the job! It doesn't look much different from a CFL driver circuit from a TFT monitor.

Looks very much like a stretched out CFL ballast!

So far we've managed to light a 6 footer at roughly a 3rd brightness on this!

LOL, good test Tom! I've managed to light an 8' 100W off a ballast out of a 9W GE stick! Shocked

And we tried a dead 20w T4 on a 250w merc ballast with little joy LOL!
