Hi - I have a room lit by two undimmed strings of six x 4.5W MR16 no-brand non dim lamps. This system originally had 50W halogen MR16s and 2 x 300W torroidal transformers. Visually this was OK, but video flicker on a webcam was terrible with the LEDs (none in daylight or with a halogen lamp). Our electrician replaced the transformers with 45W Lyyt LED drivers, andthe flicker is now a slight shimmer.

MR16 LEDs - less video shimmer from dimmable lamps? 1606410214444 - EletriciansForums.net

Question - Would replacing the lamps with quality dimmable MR16 lamps (rather than no dim) reduce the remaining shimmer, or make no difference? If not, ideas to get rid of it please?

Thanks, Max
 
TL;DR
I have a room lit by two strings of undimmed no-name MR16 LEDs with Lyyt LED drivers. There's some residual lighting shimmer on video cam footage to Zoom (no shimmer in daylight). Might replacing the MR16s with dimmable lamps get rid of the residual video shimmer, if not what ? Thanks, Max
The flicker is probably coming from the rectifier (not smoothing enough) or the voltage reducing circuitry (chopping on and off) in the lamp. Try running a lamp off a 12v battery, if the flicker goes, then the fault was the rectifier, so the solution is a high quality dc power supply. If the flicker remains it must be the voltage regulation part - get new lamps :/
