Well here's another article that will probably get quickly outdated. Remember those 240 LED Bi-Color (Color Changing) on camera LED lights from here: https://cheesycam.com/color-changing-dimmable-240-led-video-light/? Well, I was lucky to grab a set and then they were gone, never to be seen again. Apparently there might be some type of exclusive distribution that won't allow them to be sold on eBay, but if you really really wanted them, you can find them for almost twice the price at some retail locations.
So for on camera lighting that adjusts to the ambient, you've got a choice on the 312 Bi-Color LED lights which 'totally rock' BTW (I have a set and will do a video tomorrow), but those are still running about $230-$499. Here's an interesting one that just showed up and comes in a bit cheaper with 277 LEDs from maker Socanland with the same color changing features and powered by what looks like Sony style batteries.
States only two available at this time, so this could be one of those times it's here today and gone tomorrow. Apparently Socanland was at NAB and are manufacturers of other large LED video lights. The only video I could find about this company is the one below on some larger 1x1 sized light panels.
So for now, only a few of these smaller 277 Bi-Color Changing Dimmable LED Video lights from Socanland are available along with a 310 Bi-Color version. Personally the 310 version looks overkill on the whole digital display and I feel it's overpriced. You would be better off with the 312 Dimmable Bi-Color LEDs if you wanted to go that big.
Not sure how long this company has been around, but it looks like in the near future we could be seeing a line of Socanland products competing in the LED Video light market.
