Thank you for the kind words.
PWM and camera shutters are funny bedfellows.
On some lights, I can see it on the iPhone, but not really see it in the light itself.
One the LT1, I didn’t notice any PWM on the videos.
By mine eyeball, at the faster 15.9kHz PWM, all I see is light.
At the lowest brightness setting. The PWM is at 3.9kHz, and Duty Cycle is very short at 1.3%.
This is just in the realm where (I think) I can just detect something by eyeball.
But only in a full dark room, and moving something very fast through the beam.
But perhaps I am fooling myself. A double blind experiment is hard to do alone.
It certainly is not bothersome – IF - I can actually detect it at all.
There are some more O-Scope shots in this POST:
So, I really think my answer is, I can’t see it with my eyeballs.
All the Best,
Jeff
