All times are GMT Ldd-1000hw Quote message in reply? I'm hoping someone who has looked at the LDD output voltage with an oscilloscope can chime in whether there is any significant LF voltage ripple.
If there isn't anything significant, I'm not sure how much worry there is about syncing or flickering on the output side These diodes will be heating as well 0. Safety depends if the Meawnell is also measuring switch or inductor current and not just LED cathode current it's possible. Sent from my iPhone using Tapatalk.

I believe karimwassef tried the one from Sure Electronics with success. See menwell new leaf growing. If you're seeing this message, you haven't met them yet.
