    Vdm issues with reefbrite and temp probe

    I have a reefbrite 250 w mh ballast connected to a vdm module. When my light turns on , my temperature probe reads 10 degrees more instantly. Since I have the temp turn off the light in case of overheating, it keeps turning the light on and off. Any clue why this is happening?
    thx

    I would check cord routing first. If that light is in the same cable bundle as the temp probe, it could be inducing EMF in the temp probe cable, which skews the readings.
