Optivisor loupes have been good for me. I still have one I purchased in the 50's. In a previous thread I mentioned that one of my dad's hobbies was cutting and polishing diamonds. He won awards for some of his stones. He used Optivisor loupes, mainly the 7x. I, also, use the 7x as my "go to" loupe. That worked well for me when I was making jewelry as a hobby. I also used it for shop things like sharpening drills, removing splinters, etc.
I have not seen the LED attachment; it sounds great.
First of all you have to be smarter than the machine.
