APEXEL 37mm 52mm Thread Macro Lens Fill Light, Portable Camera Lens Ring Light with High Power 32 LED/CRI 95+/45 Light Modes for APEXEL HD 100MM SLR Macro Lens Attachments

Nice light, but a few quirks. I use it with a macro lens on my tablet. The light is threaded so it screws on where a 52mm filter would go. But there is no thread on the front, so can not add a filter to the front of the light. There is a ridge on the front, so an inside thread lens cap works, but is recessed and hard to get on and off. I wish I could put a UV filter on the front, then I could easily put a lens cap on that. Once you screw it on the orientation is what you get. No option to rotate. In my case, that makes the buttons and USB C hard to get to when on my table or phone. Good, but could be improved.

Only 20 minutes when on full brightness. I expect it to have a faster drain but relative to the description that states "2 to 7.5 hours".

Battery does not last very long

Light wouldn't turn off till it ran itself dead and then won't come back on.

Missing the device that attaches to your phone. Make sure to order it separately. While the product is good, the marketing is terrible.

This little light really helps your macro shots 100%! It’s worth the money, look at how much clearer my shot gets with it on. Perfect for texture shots.

I use it on my camera and it makes up nicely for my lack of macro photography lighting.

This is a pretty good fill light. The process of using it is very simple. Just mount it directly on the lens, turn on the fill light and use it.
