No flicker to naked eye or video in hispeed.
No hum/ noise
I'm very sensitive to flicker, and Waveform's TRIAC power supply gave me headaches and made me see the strobe effect when things moved. I replaced it with this power supply, and it's wonderful! There is zero flicker and any light level, and it works perfectly with my Lutron phase cut dimmer.
I can't recommend this product highly enough. I've suffered with flicker for years, and this is the very first efficient lighting setup that's dimmable and which doesn't flicker. Only incandescent bulbs worked as well for me, at many times the power usage.
I heartily recommend this product. I am using existing wiring and a wall switch dimmer for a length of white LED strip light. I had tried two different types of power sources from another manufacturer and in both cases I suffered with line current-related 120Hz flicker – as in visible jitteriness when objects under the light are in motion and as indicated by dark bands in a smartphone camera viewer. Results were the same with either a dimmer switch or a standard on/off switch. I was fortunate to get in touch with Josh at Waveform Lighting and I became aware of how unusual it is to find a wall switch dimmable power supply that does not pass along flicker. Then I installed Waveform’s Centric Series Flicker-Free Dimmable Power Supply and the results are perfect. No more visible or smartphone-indicated flicker. Just good solid pleasing light with wide range of smooth dimming. Thanks Josh and all the good folks at Waveform!
