Thanks Dan. Actually... that strobe effect on the roof line are just old fashioned strobe lights! Here's the thing. I have always used the xenon arc, u-tube style strobes to line the roof. This year, a local guy and I split a 100-pack that was on sale and I planned on also doing the "wrap the megatree" with strobe approach that I've seen so many people do over the years... well, in this first song I sequenced, I tried the sparkle effect and son of a gun.... that looks WAY better than any strobe could ever look IMHO because I can make it super dense without requiring a ton of $5-6 strobes... Now, the reason I still use them on the roof is that my roof consists of Technicolor lights with the c9 diffuser bulb cover... and that obviously immensely limits the impact of the sparkle effect out of xLights...
So, to answer your question, there are approximately 25 strobes on the left-side, two-story portion of the house and then another 15 or so on the garage gable on the right. Now that I know I'm not going to use them on the megatree, next year I plan on doubling those up.
