Folks - sorry I have been off for awhile, and not sure how often I will get back. If you are going to buy lights for miscrope photos, and general work, try to get a single head COB led with a flexible neck. Ikea sold some really great ones but no more. You could often get for 10 bucks. They must be out there somewhere yet. Now Ikea carries
this.
It looks like it has a hard stem rather than flexible to the base. and the head looks larger in diameter than the old one. I don't know if it is as bright.
I think
this is the old one.
be sure to get the 115V. not USB powered.
While the ring lights are good for many tasks, like Jason says, they won't get close enough at the higher magnifications, and they will leave a halo around many images you may not like. The small COB lights will fit even when your working distances get down to a cm or less.
one other item if you are buying scopes for macro/micro photo. Try and get one with with course and fine focus. The fine focus will make photograpy much easier, especially when you start stacking images.
