I ended up going with basically what I have in post 13. Spacing is roughly 6'. The gunite crew didn't get the memo, so they had some issues with placement. Fortunately it was a 2-day shoot. I got the only 1 impacted installed after the first day as I noticed it before the gunite was too dry, then they got the other 3 in on the second day. I honestly think 4 lights will be a little over-kill for my pool, but my previous pool didn't have enough light and I would kick myself if I made that mistake again.What did you end up doing with the lighting layout? How many and what was the spacing? It looks like you have good even coverage, I can't wait to see it once the pool is full.
I had to lay that out for our PB, as our designer did not really want to commit to a layout. And after I had the initial layout, which was easy, I learned a few things about pool construction that forced a change. I'm hoping it comes out ok.
Its funny because my inspector today said that I had more transformers than he's ever seen. I have 5 of them because I can control all zones separate. Pool/Spa/Sheer/Bowls/Bubblers. Probably not the most cost effective approach, but I think it will be nice to have that kind of control.
