I recently purchased five similarly-priced “selfie lights” for smartphones, with the intention of keeping one – which ever one fit my phone’s case best – and giving away the other four to my friends. I specifically attempted to buy five different models, understanding that we all have different phones and different cases, in an effort to find options that would maximize our chances of all finding a good fit. All are rechargeable using short USB cords; none require AA or AAA batteries. These two items are nearly identical and arrived in nearly-identical packaging. The first one is a little brighter than the second, on all three settings, and has a black back. (In fact, this first model was the brightest out of all five lights that I compared.) The second one has a white back. On both, when trying them on my Galaxy S8’s front-facing (selfie) camera lens, I found that the light from the ring was so bright and diffuse that it confused the camera’s sensors and led to undesirable haziness in my images. This product would be better if the light was more clearly directed to the front of the ring and not also shining through the sides. If I were using this product, I’d have to add dark electrical tape to the perimeter in the hopes of remedying that bleeding light problem. #1: https://smile.amazon.com/gp/product/B01NACUC38/ref=od_aui_detailpages00?ie=UTF8&psc=1 Auxiwa Clip On Ring Light for Camera [Rechargeable Battery] Selfie LED Camera Light with 36 LED for Smart Phone Camera, Round Shape, Black #2: https://smile.amazon.com/gp/product/B01HXTHPXU/ref=od_aui_detailpages00?ie=UTF8&psc=1 QIAYA Ring Light for Camera [Rechargable Battery]Selfie LED Camera Light [36 LED] for iPhone iPad Sumsung Galaxy Photography Phones, White These next two models are exactly the same. They’re just being sold by different companies, under different names, in different packaging. Buy which ever one is cheaper at the moment. Neither fit well on the Otterbox Commuter on my Samsung Galaxy S8, when using the rear-racing camera lens, but both were fine with the front-facing (selfie) lens. #3: https://smile.amazon.com/gp/product/B01MCZ2WY8/ref=od_aui_detailpages00?ie=UTF8&psc=1 Auxiwa Clip on Selfie Ring Light [Rechargeable Battery] with 36 LED For Smart Phone Camera Round Shape, White #4: https://smile.amazon.com/gp/product/B01MZ23563/ref=od_aui_detailpages00?ie=UTF8&psc=1 FeBite Selfie Light, FeBite LED Selfie Ring Light Rechargable Battery iphone 7 6 6S Plus Samsung Galaxy S7 S6 Edge Plus Note 5 4 3 HTC LG Blackberry Motorola for Perfect Face Slimming Brightness (White) The following dimmable selfie light technically has more lighting levels than the other models; however, I think the other models are easier to use because it’s simpler to click the button once to get to a brighter level than it is to hold down the button on this model, then release it at exactly the precise moment to hit the optimal desired brightness. But this is the only model compatible with the Otterbox Commuter case which protects my Galaxy S8 and the rear-facing camera. (All five of the models above worked fine with the front-facing camera lens.) So this is the model I’ll keep for myself, as I give the others to my friends. I appreciate that it comes with a little bag, to use as a carrying case if you’re throwing this ring light into your purse or backpack. #5: https://smile.amazon.com/gp/product/B01M4O2QGT/ref=od_aui_detailpages00?ie=UTF8&psc=1 LEICESTERCN LST Selfie Light Rechargeable [38 LED] Dimmable Clip Ring Lights Fill-in Lighting Portable for Phone, Tablet, iPad, Laptop, Camera (White)
