Simple, when you switch it on or off, let it stay in that state for at least 3-4 seconds before making the next switch change. So, switching it off and quickly back on cycles the scene. Switching it off and waiting at least 4 seconds or more leaves it off and in the same state when you next turn it on.
The switch on the lamp itself cycles through the lighting states, once on, via a quick flick off and then back on.
Yes, I use 4 of these in a 4 bulb fixture in my bathroom over the mirror. They have to be synchronized. I love the effect and sometimes when I want brighter light I flip the switch until I get the type of light I want. If they get unsynchronized, just unscrew them and the rescrew them in to get them back in sync!
NO -Home Depot guy said yes but got it home and put in lamp first click no light, 2nd and 3rd click light goes on but stays at same wattage.
Yes. Even unscrewing and screwing back in works.
Yes it can, providing the bulb fits.
These bulbs are 80 CRI
I have two of these in my ceiling fan light. Two of more bulbs will stay in sync if either turned back on promptly (changes scene) or turned back on after several seconds (comes on at last scene used). If turned off for a certain length of time, like two to four seconds one bulb may advance to the next scene but not the other. Turn one bulb off and on by unscrewing and screwing back in will get it back in sync. In normal use they will stay that way.
