This blog is about FLII mini ring lights. They are about 3 inches in diameter, and feature about 40 led emitters. The color temperature is about 5000k to 6000k which means that the lighting is cold. They are also rechargeable, and last about 2 hours with a charge time of about 1 hour.
They are no comparison to natural light, or the larger 18″ ring lights and you constantly have to recharge them and they only clip on to to things that are less that 3/4 inch thick.
The only real advantage this light might have is that is that they are portable and affordable. They also offer an inexpensive way for “do it your self” lighting because they are clip-ones.
