HBR, wouldn’t that be, “I am still MICROscoping out electrologists.”?? Sorry, couldn’t resist! 
I am new here, as are you, and just starting to use an epilator at home, so have nowhere the experiance level of any of the pros here you will read of. Dee & James both swear by quality eyewear; Dee uses custom loupes, James has the scope mentioned. While there are a ton of other things that can make for a good or bad treatment, let me tell you that having good lighting and good vision equipment makes a LOT of difference!
Good eyesight plays a role when using low power mag, such as a mag lamp, I am sure. And while my vision is still ok, I recently had to get glasses myself. And I tried some different mag ideas, looked at circle lamps, clip-on mags, and loupes, and even had some professional input while I was trying the equipment on.
But let me tell you, I got some 5X loupes, and while they are not custom like Dees (so could probably be better), and not as nice as James roll-around self-standing scope, in my vast 4 days of electrology experience (that’s a joke, folx), the loupes have allowed me to “hit the hole” much faster & easier than I think any mag lamp ever could. Sure, it takes getting used to, looking thru the loupes (read my other posts, there IS a learning curve), but once you start to get the hang of it, it’s more like looking at pencil leads than hairs.
Of course, when the client clears their throat, those pencil leads move quite a bit… (movement is 5 times larger as well as the hairs), but I am glad I listened to Dee & James and spent my $$$ on loupes instead of a lamp.
On the lighting note, I am using a 20W halogen lamp, and with the lower wattage, am able ot position it CLOSE to the work area, but I am considering buying a brighter, larger light source. A 100W halogen flex lamp can be had for around $100-150.
Good luck in your quest, HBR!!
