This is a brief review. I needed a fill light kit for a shoot in the Netherlands, and I did not want to travel with it from California. I purchased three of these lights and three stands as a kit from Amazon Germany. They were delivered to my hotel in two days. The stands were light, short and cheesy, but they were OK. I wound up using mic stands for two of the lights.
The lights: two knobs for each of the two colors. Can be powered by Sony batteries. They actually look decent. They come with power supplies, not a super long cord. No remote. Totally silent, no flicker. No fan. Did not really get warm as the whole case is one big aluminum heatsink.
There's a diffuser which is your typical thin plastic sheet which clips in. It actually worked rather well. I did not use an umbrella, as it would have really not let much light through.
The quality of the light, while not super bright, was excellent and the closeups have a natural fill light. Just what I wanted. OK, there are better lights, but for the price this was pretty amazing.
Not much to say except that this is a good, cheap, well made light with high CRI. They were super lightweight and came with a soft case. Pass on the stands unless you need short, light ones.
Here's the Amazon description, with photos. etc. This is the kit I bought. Of course, I paid the same price in Euros, not dollars, so it was a bit more, but really that's cheap for three lights and three stands.
