the problem you will find with the Office Depot circle lamp is that it was made for artistic drafting, those lights are usually set up in a specific place and never moved again. Electrolysis circle lamps are moved around a lot, and an inexpensive drafting model will actually break from all the moving around. How do I know this? Guess who had the same idea when he was an electrology student? The things never lasted longer than 2 to 3 weeks.
As far as magnification goes, you will want as much as you can get, the problem with using a circle lamp to get high magnification is the higher the magnification, the shorter the focal distance, and the closer the circle lamp needs to be to the treatment area.
A particular electrolysis student who ran through a bunch of office depot circle lamps, also got some higher magnification lenses, and the 5 diopter was such an improvement, that he got a 9 diopter, only to find that while it did improve the vision, it had to be so close to the skin that he was scraping the tweezers on the lens and sometimes burning his hands on the light ring.
If you go with a circle lamp, you should get a Dazor or a Luxo. They are designed to be moved around like an electrolysist would need to.
This leads us back to another reason it is best to do home electrolysis with the buddy system. What works best is the highest magnification you can arrange, while having a focal distance that does not present challenges to accessing the treatment area, and for most, that turns out to be a stereo microscope. Loupes are a distant second place, and circle lamps are just ahead of eye shield lenses. None of these makes it easy to work on yourself, but one can easily look through a stereo microscope at someone else, enjoy the view of 10, 20 or even 40 times magnification and a focal distance that allows one to work without encountering the vision equipment with your work tools. If you are working on yourself the circle lamp is probably going to be the thing to use, as while it doesnât have great magnification, it can at least be set up to where you can focus to see through its sweet spot and do your work on the body part you select, as long as that is not your face. For what limited areas on the face you can work on, you will need magnifying mirrors and a good bright light that can be directed to the treatment area in a concentrated beam.
So one more time, get a buddy and work on each other, as working on oneself is so far from ideal. In school we only work on ourselves to do legs, and that is only to develop a feel for what both the practitioner and patient are feeling during the work. The idea is to know that when you feel this, the person you are working on is feeling that, and hopefully, one will develop a touch and feel for insertions faster than any other way. Once that is done, a student is never advised to work on themselves in school again. It is all about getting good at working on someone else with the skills that exercise has given them.
