Most electrologists use the regular Estheticians mag lamp which is good, but if your eyesight is not great you will miss a lot of hairs. I chose to use the medical loupes that dentists and doctors use. I am able to see and remove more hair than most electrologists.
I recently asked someone to come in and work on me. I could see I had a lot of hair growth around the corners of my mouth. Even though they were very short because I had trimmed them I knew if I was able to work on myself this was hair I could remove. The person I called used the mag lamp I have here in the office. She kept saying she didn't see much. Alas I will have to wait until I can plan a trip to visit another electrologist friend out in CA who uses the same loupes I do.
