Ultra-Slim COB LED Ring Light with Universal Quick-Release

THE PROJECT

Stop using bulky camera lights that stress your lens motor. This Ultra-Slim COB LED Ring Light features an instant Quick-Release mechanism for seamless lens swapping. Powered easily by any power bank and engineered with heat-set threaded inserts, it delivers uniform, shadowless lighting for professional macro photography.
Thanks to COB LED technology, you will get continuous, soft, and perfectly diffused light, saying goodbye to the annoying "dotted" effect of traditional LEDs.

KEY FEATURES
* Universal Lens Fit: Fits all camera lenses with front filter threads without overtightening or scratching the barrel.
* Instant Quick-Release: Swap, mount, or remove the ring light in under two seconds.

* Portable Control Box: Features a printed belt clip housing the electronics (power switch and PWM potentiometer for brightness control).
* Built to Last: Uses heat-set brass inserts to ensure your threads never strip or wear out over time.
* Ultra-Light & Slim: Minimum footprint to prevent camera front-heaviness and lens autofocus strain.
* Portable Power: Perfect for outdoor shooting, just plug it into a standard Power Bank via USB.
