These Kentfaith digital microscope LED fill lights are ok. They come simply wrapped in plastic and thats about it. The two lights are on a clip that I guess is meant to clip onto a desk to table top and reach around the microscope or whatever you want them to.
But I ordered them to go with the Kentfaith digital microscope and my review will be based on the compatibility with it.
The microscope already has two LEDs like this built into the base and are pretty dim which is why I went ahead and ordered these thinking they would be an upgrade. And boy are these an upgrade!
They actually come with a power adapter for the USB cable it is powered by and has inline controls of on/off, brightness and dimming, and even to turn one or the other lights off or have them both on.
They get MUCH brighter than the lights that come with the microscope but unless I have it near the edge of a table, it isn't a great solution because there is no way to mount these onto the original microscope base.

Overall, fantastic goose neck lights that you can use for anything at all with good controls as well. If you are ordering them to go with the microscope like I did, you might want to look for a different solution unless your microscope is near the edge of a table.
