@stan2004 posted:LED strips can be dimmed by simply reducing the applied voltage. For example, for the common 12V LED strips, they will dim as you lower the applied voltage until they are dark at about 8V (or so). 5V LED strips will dim down until dark at about 3V (or so). So I guess the snarky answer to your question is "yes."
Thanks. I was thinking of having the background buildings with dimmer lighting.
