I'm dimming a 9ft piece of manufactured LED lightrope with an ordinary
household wall dimmer.
The nice thing about using a wall dimmer is that it doesn't get hot,
it's cheap, easy to get and no lightrope mods are needed.
The lightrope has an internal diode and internal resistors to run off
120VAC.
With the dimmer full on, I don't notice any flicker.
However, flicker seems more noticeable (but still subtle) when the
lightrope is dimmed.
I suspect some combo of LED curve + dimmer waveform + eye persistence
time to account for the flicker.
So.... how to get rid of the flicker and still use an ordinary wall
dimmer?
Could I put the dimmer in series with a bridge rectifier? That'll put
the flicker at 120Hz..
Or...
Maybe design a more appropriate dimmer?
