Lighted Magnifier For Cartridge Alignment Recommendations

I’ve been using a cheap 10X loop and other assorted magnifying glasses to help with aligning carts but I’m afraid my eyesight is not getting any better and it’s just not good enough.

A light would help as on some carts where the cantilever is slightly obscured by the body. I have a lamp that I point in at an angle but that can throw too much of a shadow so I’m looking for something that has both a light and enough magnification to make the process easier. A man can go cross-eyed!

USB would be nice too.

Wondering what other folks are using for this.  I use a protractor. 

Thanks in advance.
