[QUOTE="AAH, post: 120608, member: 543"] You could make a fairly robust system by putting lengths of WS2811 strip inside lengths of white/clear rigid PEX water pipe. You would end up with rigid lengths of lights that would require some sort of butt join every 4m or 5m or whatever PEX comes in lengths of. PEX provides a fairly good diffuse omnidirectional light. The use of higher leds/metre count pixel strip would give you a brighter chase light. As you only ever have a short section turned on voltage drop wouldn't be a significant issue. PEX is pretty tough and would handle being walked on with little issue and would probably handle running spikes pretty well. The joins would have to be made water/runner proof but that wouldn't be that hard to do. It wouldn't be that hard to create chase sequences. You could use something like a raspberry pi with different sequences to match the different events. Have a search for "leaping arches" and you'll see what is done and how it looks. Because most of the Christmas light stuff is for night time it would probably be necessary to use higher than the typical 30 led per metre pixel strip in order to be daylight visible. At a guess I'd say you could create something that is usable for under $10/m regardless of length. Curves shouldn't be especially hard. I suggested the rigid rather than roll PEX as repeatedly rolling the strip back up is probably more likely to damage it. [/QUOTE]

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
