Led Lighting Accessory - Neewer Ring 48 - Any Good?

I have one, but I don't use it since it's so big. I prefer the smaller Angel Eyes LED ringlights, but you need to provide your own 12v power supply and mount the lights yourself. It's pretty easy.

Here are a couple eBay links to the Angel Eyes ringlights. I use 40mm, 50mm, and 60mm for various setups:

Has anyone tried the Neewer Ring 48 though?
That looks like something I could somehow attach right to my microscope housing.
Even if I used some epoxy and spacers to center it to the base of my scope.

This isn't the big ring on a tripod, it goes right onto the camera lens.
For $20 bucks shipped on a cheap scope I already have seems to be a worthwhile gamble to me. The whole problem with the scope is lighting.

yeah I have taking some of the smaller ring selfie lights apart and attached to my light extender and found the hertz where way to strong so it would put flicker lines in photos.

I always question when folks are worried about their lights being bright enough. Lower light intensity just means that exposure time has to increase.
