Thread: LED light for lathe.

Have you measured the 24VAC?

I vaguely remember having an issue like this on some led light or other I had on my mill. If I recall correctly the problem wasnt 50Hz flicker as such, it was the LED driver shutting down over V. (ok so you still got 50Hz flicker). did you try leaving the bridge in and forgetting about the cap?

On my lathe if none of the contactors are closed the V goes high enough for the LED to shut down(some times). If one contactor is closed it stays on. One of these days I'll find a larger resistor.

p.s. I'm going to have to buy some of that LED strip!
