Review on Obeamiu 540 LED Video Lighting Panel: Dimmable Bi-Color 3000K-6000K for DSLR Camera Studio Photography, Includes Remote Controller/AC Adapter - Perfect for Video Shooting, Live Vlogs, YouTube, Zoom Calls! by Kurt Ferguson

This lightbar measures 8" x 10" and mounts to your DSLR. I have a Nikon and it works fine for a top mount. It also has a battery compartment (sold separately) but can be used with the included power cord. The bottom bracket can be tightened or loosened to allow it to slide over the top of the camera and then adjusted to keep it from falling off during use. It also has different light levels adjustable through the arrows around the power button. I am a hobby photographer and take product photos for practice. Studio lighting was a challenge for me as I was also balancing between ISO, shutter speed and aperture. This light bar is a great addition to my hobby for many reasons. First, it allows me to lower the ISO so I can maintain a faster shutter speed and hold the camera when shooting manually. Second, it adds shadows that I need and removes shadows that I don't need. Third, it allows you to take closer pictures without losing focus due to aperture settings. I have attached three images as an example. The first image (1) was taken at ISO 800. The second (2) was taken at maximum brightness of the lighting panel and ISO 320. The third (3) was taken with the lighting panel at minimum brightness. and ISO 640. I was a little worried about the weight of this lightweight panel as it feels a bit heavy. However, once installed on my camera I didn't find it to be too heavy. Since this light is constant and not a flash, I was able to adjust the lighting settings before taking the picture. I would recommend this light to anyone learning macro photography or product photography as you can learn your settings and practice seeing the difference in each photo. It also works very well with video footage.
