This product is a magnetic phone light designed to meet the needs of mobile photography enthusiasts in low light conditions. The base of the light is equipped with a magnetic design, allowing users to conveniently attach it to the back of an iPhone with MagSafe functionality or a compatible phone case or use it in conjunction with the PGYTECH photography handle. The light features a ring-shaped design that satisfies the needs of users for a "catchlight" effect when taking selfies (similar to the annular light that appears in the eyes, similar to the effect of coloured contact lenses). The ring part can be opened via a hinge so it can be folded 180 degrees and stays hung at any angle. The light is powered by a built-in 300mAh lithium battery, which can be charged via the Type-C interface at the bottom. It can provide up to 45 minutes of high bright lighting (test reservation). The front panel of the light has a single button: long press to turn it on and off, and short press to adjust the three colour temperature settings in one cycle. Users can also adjust the brightness of the light by touching the panel and turning the finger. The biggest design advantage of this light is its thinness. We have managed to keep the overall thickness of the product to only 10.5 mm, significantly thinner than most comparable magnetic phone lights on the market (which usually have a thickness of 14-15 mm), achieving an extremely lightweight and slim design.
