is it a digital ballast? if so b careful.
Hey all, after working in a hydroponic store and hearing many of the stories that float around, an easy way to get busted without realizing why is from any ballast that gives off a strong RF (radio frequency). Many digital ballasts are easily detectable from the air, and that is why special RF jamming materials are always recommended with growing. To illustrate this effect though, if you have ever used a tri-meter with an electronic ballast in the room, it is an interesting experience. Many of them are not RF protected so the numbers jump by the 1000's in a matter of seconds and do not settle.
