I have just bought Caldwell chronigraph from Amazon It came to me from Las Vegas . So the label says . It works well in natural light butI can't get it to work inside my workhop either day or night i have tried led and incadescent lights and made sure no fluorescent light is running. I have seen the same machine running on you tube with just an ordinary table lamp. Any hints would be appreciated.
Glad you got it figured out.Just out of curiosity, may be relevant or not...Over there in New Zealand are you 240v 50Hz?

DC provides a constant stream to the LED's, AC provides light 60/50 times second.
