    Hello. This effect is referred to as pulsing not toggling. As in Pulse Width Modulation or PWM and it is what Solid State Relays were made for. Because the moving parts in a traditional relay would fatigue and wear out and also the repeating collapsing fields from the coil being energized and release so many times would wear down the controlling electronics. I say as long as you are using a good quality SSR then you should be fine. Once setup and running you will most definitely want to do the PID autotune thing. I am running a 1000w mains powered silicone bed heater on my TronXY build. I used a genuine Crydom SSR. And while some say it is not necessary I got a heatsink for my SSR just to make sure everything stays cool. The most important thing to remember in our setup is the protection device for the worst case scenarios. This comes in the form of a thermal fuse that should be wired in line with one of the power wires to the bed. I am using a 133c thermal fuse. It is taped to the bottom of the silicone bed heater with high temp tape. This way if for any reason the bed achieves greater than 133c it will break the power circuit before setting my home on fire. DO NOT overlook the safety. Best advice anybody could ever give anybody ever. Be Safe.

    So if I have bulb on the same outlet it will flicker but only from that socket, but everything else seems unaffected. A few days ago I thought it had a greater reach but then realized the florescent tubes were slowing dying out and weren't related.
