All LEDs are equally bright way, and have the same color temperature - so it should be!
The diffuser is also good. The other discs I have not tried yet, so I can not say whether the Kelvin values agree. The discs are housed in a nice way, plastic case. Nicely, I also think that you can completely close the back cover with inserted AA batteries. In the pictures here I thought at first that you may even see the batteries.
I have used light all night during the shoot repeatedly and the batteries are almost discharged! The articulated find the way absolutely ok for the price. The articulated joint can be adjusted easily and still holds the angle perfectly. I make the adjustment anyway with the Knick Eiger from the tripod, where I have it screwed the lamp. On the hot shoe, I have not tried to use the light.
Conclusion: A bright light at an affordable price that can offer many a lamp containing more LEDs should Paroli. My recommendation therefore: Dear two of these favorable lights as a buy then but not more expensive brighter light with more LEDs. Because with two - also still good - lights you have in the illumination but more options.
I definitely consider yet to order a second me.
