Who here can maybe help with looking at the output ripple of an LED driver through an oscilloscope?
Thank you very much.

Also, I'm wondering if this is just the lamp design and I need a new thing all together.
Does your eyes see the ripple? or is it only on the scope?
What frequency of ripple? (time or frequency)
Some LED drivers turn on/off the LED at about 1khz. For half power the LED is latterly off 50% of the time. Other LED drives reduce the current to 1/2. Until I understand what type of "PWM" I can't comment.
Send all the information you have.

I would guess it's the design of the lamp.

Your power supply could be the issue here. I always check that first.
