Update if anyone is following.   I got some sched 40 PVC.   Seems to be some confusion on the gauge of pipe.  Sched 40 at 1" is rated at 440 PSI.     Sched 80 is thinner and rated at 200 PSI.    The higher the gauge the thinner the PVC pipe.

I think you're the one who is confused.  Schedule 80 is far thicker than schedule 40.  Maybe you're thinking of CL-125 (short for Class 125) which is quite thin.  Different scale.

PVC Pipe Sizes Chart

PVC Pipe sizes are different than the size the pipe is called. For example, a 1 inch PVC Pipe is actually 1.315 inches in outside diameter, and 1.029 inches in inside diameter. Fittings follow this same pattern, a 1" fitting has a 1.315 inch opening to accept a 1 inch pipe, which actually measures 1.315 inches in diameter. The opening in the fitting and the size of the pipe are exactly the same size; this is called an "interference fit" and the two parts are intended to be "welded" together using PVC glue, which is really a solvent that melts the two parts together.

How many lights should I use for each one foot channel on my arches?  First time doing them and I want to order the right amount of lights.

What type of lights? AC, dumb or smart.

Most list Lighted Length (first to last bulb). Be aware that AC mini-light strings can not be easily cut (shortened) as each bulb drops a portion of 120V.

Smart or Dumb RGB can be cut (at marks for ribbons), but you will need soldering skills for the remnants (💡 keep some for repairs)

Another metric is bulb spacing . LOR bullets are 6" spacing, I happen to use 4" spacing.

Another pay attention is total Amps per port  and run. You might need to Power inject (dumb,but NTE channel limits or smart)

Just regular LED mini lights

just saw something where someone used 200 lights per 1 foot channel. wow, that seems like a lot.

Sorry, I did nor scroll way back before asking.

Mini lights do not change color, so the person may have also run 4 strands : Wh, Rd, Gn, Bu.  But even then, 200 / ft . They may be doing an outside wrap on 2" tubing. That eats a lot, fast.

Watch your end to end count if using Incan Minis, the limit is usually 3  or 4 strings  or you may blow the PLUGS fuse in the first.  LED ones are in the 30's

Using LEDs so string count won't be an issue with fuses.  The one I was referring to was wrapping 1' pipe and used 200 per ft for just one color. I guess the more the better, it cant hurt. Just a lot of wrapping.

Get some more opinions, because I think that density is insane.
