Review on 🔦 Adjustable 144 LED Ring Light Illuminator for Stereo Microscope & Camera - AmScope LED-144W-ZK (White) by Jamie Behm

Works great. Easy adaptation to 12 V gel cells for mobile use. Remember that the center is positive, not negative, as indicated by the symbol. If that doesn't work, change the wires. Failsafe (13VDC or less). I use it with the macro setting on the camera, not on the scope. The screws are long enough to easily attach to the front of my lens for hands free use.
