Thanks for the info
I heard somewhere that a digital ballast can interfere with other signals like Wi Fi or TV is that true ?
a good digital ballast will be electrically quiet. I own 3 Lumatek ballasts, and even when all three of them were going I did not get interference on any of my devices or on my very sensitive ham radio equipment.
Exactly... not only are they well shielded and already pretty quiet, but they also oscillate at a much higher freq than normal for an inverter circuit, I think it was around 26mhz. This not only provides much smoother operation of the light, but by the time you double, triple, quadruple that frequency to figure out where all its harmonics are, you are immediately out of the HF frequencies and well up into VHF and UHF, where propagation is at best line of sight and no more than 7.5 miles... if you had a good signal. A practiced RF snoop would have to be right on top of you to hear these things, and she would have to know what she was looking for.I have a purple (adjustable) 120V 400-watt Lumatek ballast. It did throw birdies on my "all band" (25mHz - 1.3gHz) scanner when I did a full scan. But they were all on completely unused frequencies. And even the "eff see see" wouldn't have been able to detect them unless one of their employees happened to be <7' away (in the same room). Less interference than my vacuum cleaner!
