Acriche is the world first semiconductor lighting source using AC current without convertor. Acriche is environmentally friendly however an incandescent electric lamp and a fluorescent lamp contains harmful material like mercury and lead. Acriche is a compound word with Acro meaning the top and Riche(Fr.) meaning the richness. It means SSC supports the better life through the world top class LED.

I hear they 60Hz flicker like mad.

Guess mode on.

It probably has a full wave rectifier on board so the flicker would be 120Hz

I think I remember a member testing one and saying the flicker was bad.

It depends. If it's a whole bunch of series LED dice with a rectifier, it's 120Hz. If it's TWO strings of series LEDs in inverse-parallel (a common configuration for LED christmas lights) it will have 60 Hz flicker.

Is a rectified output with a $0.02 capacitor in parallel with the LEDs to completely eliminate flickering really so much to ask for
