Then I plugged them directly to the wall outlet and no flicker at all so I ruled that out. The fact that both of your machines have this flicker is leading me to believe it has to do with the phase converter or wiring of it. My plan was to use a relay to turn the lights on and off and have the LEDs powered by 120v from the wall instead worst case. I would definitely like to know if you were able to sort this out!
    What is the supply that is feeding the Phase Perfect, this most likely is where the problem is

    What spindle motor does your machine have I thought the VF-2SSYT where 30Hp, you Phase Perfect PT335 is only rated for 20Hp max

    If you ran another supply for the leds then you could easily create a Ground Loop

    The supply is 240V. Yes the machine says 30hp on it but its "Haas Power" and not really. The phase convert can handle 280amps overload for 4 secs and 64 amps continuous which was well within actual use. I know of other people running 20hp version on the same machines without any issues and I have checked with a clamp meter during actual use and its well within the specs. As for the ground loop, could I just isolate the lights from the mounts on enclosure and just plug them in directly to the wall with a switch or would that still be a potential problem?

    That's funny Haas power, Haas does not make the AC spindle drive motors your Phase Perfect is too small for your machine Phase Perfect would not approve of your running this machine on the PT 335

    The supply is 240v but how many amps do you have for the supply the voltage is unimportant the amperage is what is important

    When you want to run something like this on single phase your supply has to be 1/3 more than the machine spec's

    It's the 355 model and the supply is 150amps dedicated with 125amp breaker on it to phase converter and was all installed by an electrician . The "haas power" is a joke because anybody who has one and compared to another machine can tell you that they rate their spindle power differently than other manufactures. I already disccussed it with phase perfect and they said they had other customers running doing the same thing with no issues. They said they can't "guarantee" that it will be enough but would allow me to exchange if I were having problems. So far I have no problems other than the LED flicker while the machine is estopped and hardly drawing much power in the first place. If the problem only occurred when the machine was actually cutting it would be a different story but it's always flickering slightly no matter what, which leads me to believe it's something else. The OP is having the same problem with his 30hp model as well, so I would really appreciate to focus on that.

    The OP is running 2 machines which is way under powered for what he is doing, this does seem though that if this is the machine lights then there is a problem how the lighting is wired Led lighting does not normally cause this problem

    Its like I said if your machine runs without any problems then you don't have a problem, you have a light problem which could be just a wiring problem or how the lights power is being supplied, led lighting have there own power supply source something is wrong with this part or it's supply

    I have the Led lights in my machine also but don't have this problem I run a PT 380 Phase Perfect

    Why is your machine in Estop should never be used unless you have an emergency
