An advent wreath with the 4 candles of advent, light each one individually. 2LI with projector light preloader, 1LI without (you only need one preloader in your scene, they make the light transition when lighting and extinguishing candles immediate instead of loading). There is also a non projector light version, and one without any cast light, that just has glowing flames, if light sources mess up your scene (1LI each). You can edit the amount of light, radius, color, etc. while they are lit, and the settings will be remembered when more candles are lit or extinguished.
You can find this and more in world at the elephant.
