Here is IGs reply
I don’t know where he got that information. We’re running the drivers @ 240 kHz. To equate that with AM radio bandwidth; @ 560 kHz we operate at less than half that bandwidth.
In lay people terms what it really means is that when compared to 60hZ magnetic or 50kHz digital ballasts we simply operate at a much lower current but a higher frequency to excite the gasses via the two coils that wrap around the glass bulb. The driver, cable and coils are all insulated and we meet all FCC standards for EMF suppression which without the use of electrodes is exceptionally energy and PAR efficient when compared to electrode style lamps.
Hope that helps

EDIT: I picked up a potential tip from a IG v hps YT video. For those who use IG for the first time, on a strain they are familiar growing, the IG may not do as well as advertised. HOWEVER, it seems the next gen of clones (and likely seeds) will be acclimated to the IG bulb spectral balance and then outperform 1000w
