“RGB fan” is a remote control for controlling color and dimming of light. When you use it, you only need to point the fan to the lamp you want to control. We have a red, a green, a blue, and a cover fan with a screen on it. The screen shows the changing of color. The color/dimming of the screen and the lamp will chang with different angle of each fan.
If you really like a certain color and want to keep, we have memory cards for people to keep colors. There are 5 memory cards on the recharge set. When you want to keep a certain color, you just need to take a memory card from the recharge set and put it on the screen on the cover fan. The memory card will copy the color. The memory card will also change to the same color. So next time when you want to use it, you can easily find the exact color you want.
