Re: Arches for next year- advice needed
I did 20' 3/4" PVC based arches (that end up just under 6' at the apex of the arch) with 8 segments per arch. The segment length ended up around 29" and to tightly cover the segment, I needed two 50 led strings per segment. It is BLINDINGLY bright as it turns out that with 4" spaced strings on 3/4" PVC- the LEDS all end up on the same side of the pipe. I believe I could have done a single 50 led per segment with the LEDS more spaced out but then the LEDs likely would not have ended up all facing forward. 70s would likely work really well especailly if you are not doing 20'. The best thing you can do is to get a small length of pipe and prototype it to see what you like. See how the leds wrap, what spacing looks good, etc. Then duplicate.
I wish I had known about the 1" drip line techniqe BEFORE I wrapped 2 20' pipes with the 32 50 LED strings straight to the pipe. THAT is not something I would recommend to anyone.
One tip for LED orientation on the pipe is that if you are wrapping and everything is lining up like you like, then you hit a stretch where it seems like they shortend or lengthened the wire- take a look at how tightly twisted the string itself is. A loosely twisted string is longer than a tightly twiasted string. By simply addjusting the twist, you can adjust where the LEDs end up on your pipe.
Hope this helps,
