The light panel works with F550 SONY compatible battery (the package includes two batteries which is great as I can recharge one while using the other). I own several light panels and this panel has a couple of unique features that I like (1) touchless switch lets me save the battery life by turning it off and on quickly. Once I set up the light level and color I can turn the light on and off without having to move the panel or fiddle with the switches. With the other panels I need to either move them or reach around which may reposition the lights (2) I can control the color of the light without using filters. This light panel also has a switch that changes the light intensity. This feature is not unique to this panel, I consider it a must-have feature as it is incredibly useful.
Another minor but nice feature that my other panels do not have is a button that ejects the battery. This will prolong the panel light. I dropped and broke one of my old panels trying to remove a stiff fitting battery.
The panel comes with a light diffuser. I like that it snaps in snugly into the panel and does not fall out even when I turn the light upside down.
The light panel generates continuous light. Once you turn it on the light panel stays on. This panel does not communicate with the camera like a flash. I use it mounted on a tripod so I have more control of how the light is directed.
The photo panel is 5" by 3" and 1.5" deep. The light weighs 8.15 oz. It 216 LED lights.
Color temperature of the lights: 3200K-5500K
In addition to the extras I already mentioned the package also includes gloves which are sized small (I have small hands and they fit me perfectly) and a cleaning cloth (7.75" x 7.75").
Overall, I like this light very much. It is easy to set up and easy to change the amount of light I get to fit any situation.
