240 fps flicker free lights? Any ideas?

[Snaphook]

Trying to locate some flicker free room lighting for filming with 240 fps.
Maybe something battery operated with a plugged in charger would work?
Interested too see if anyone has some ideas for this?

Most linear and compact fluorescent lamp and ballast systems have low flicker.

I would think LED lighting with DC should be flicker free. They might even be good enough with an AC source depending on how they are wired up (internally).
