I've used this about three times since purchasing it, but it doesn't seem to work well with the subjects I'm shooting, so I'm selling it. Power: USB ON/OFF switch: None ↓↓↓ Quoted from the seller ↓↓↓ LED panel light for easy white background photography. This shooting light can be used in various ways, such as being installed in a shooting box as a shooting panel or used as a reflector on its own. This ultra-thin, bright, and evenly illuminated LED light makes it easy to take photos with white backgrounds or shadowless images! It allows for high-quality, beautiful photos even with a smartphone, making it ideal for taking photos for online marketplaces or documenting handmade works.
