Alex,  
Thanks for the nice feedback!  
BTW when you are playing with lights, there are some tutorials on our [wiki](https://github.com/bartbutenaers/node-red-contrib-ui-svg/wiki). And - not sure if that is useful for you - an [experiment](https://discourse.nodered.org/t/having-fun-with-svg-playing-with-light-sources/38346) with light sources in SVG...  
Have fun with it!
