There doesn't seem to be a 'quit' menu option

[terrcin]

Can't close the app once it's running :-(

There isn't. Currently I just open Activity Monitor and kill it from there.

I leave it on permanently and have it startup when my computer does so it isn't a problem for me.
I can add a Quit option if you'd like though.

+1 for the quit option. Using activity monitor for now...

+1 for quit option

+1 for quit option. Currently having to kill it from Terminal with killall when it stops seeing bulbs.

+1, perhaps a quit option menu which includes a restart button? Would be quite helpful in case of bugs
