Great Product!!! It took me a little while to understand some of the functions though so let me explain here for anyone that has questions.
There are two features that cycle through all the colors; Smooth and Flash. Smooth blends the colors as it changes and Flash has a strobe effect. You can change the color transition speed of either with the Lmp button.
There are 12 solid colors that you can choose from.
The Dim/Brighten feature always works no matter what else you have it doing.
Switch Control – Rather than use the remote control you can quickly flick the wall switch off and back on to cycle through 3 settings; 1. Full bright white light 2. Dim white light and 3. Whatever color or color cycle feature you last used.
Regular Timing – Set the light to automatically turn off in X hours where X = the number of times you hit the button in 5 seconds. Changing the color or anything else will cancel the timer.
Circular Timing – Works the same as regular timing but the light will repeat the on/off cycle every day. So if you set it at 2pm to go off in an hour it will turn back on at 2pm the next day.
(Seller, feel free to use this explanation wherever you want)

Finally got to trying these. They looked great at first. Until one of them started throwing sparks from my light fixture. No burn marks on the bulb or fixture anywhere. Happened several times before I got so scared I flipped the switch on my circuit board, thinking it was my light fixture. Put normal LED bulbs back in the same fixture – not one problem! I would love to send these back and try another set, maybe I got a faulty set? – but I missed the exchange window by 2 days!

Answer: Not sure what you are asking about a hub.

You simply screw in the light bulb to pretty much any lamp or light fixture. Turn the switch on, then tap the remote control to change the color and or brightness. You can then use the remote control to turn off and on. Light will usually have memory of your last color choice

Answer: Press one times means one hour, can be setted between 1 hour and 23hours.

Will these change from red to green continuously?
Answer: No, they will just stay one color or color cycle between them all
