[QUOTE="Kent, post: 129994, member: 33421"] When starting out last year, 12V resistor & regulator pixels didn't appeal to me due to their inherent limitations. I decided to go with 5V for some icicles that are now in their second year and working well. The good thing about icicles is that as the power (at least on mine) runs across the top and doesn't need to travel down through the total length of wire to all nodes, I could get away with power injection at the start and end of a 5.5m run of 7 drop icicles (across the front of the garage in the photo). Anyway, this year I came across the GS8208 and will be using them exclusively going forward. See the following thread for my testing comparing the 5V 2811 to GS8208: [URL unfurl="true"]https://auschristmaslighting.com/threads/a-comparison-between-ws2811-5v-and-gs8208-12v.14849/[/URL] Importing from China, you're looking at $0.20 to $0.25 per pixel (USD + shipping), so not too much of a premium with the benefit of being able to have a failed pixel not take out an entire prop. I've not had an pixels in a batch this year of ~5000 completely die, but I have had ~3 develop a fault where instead of turning off, they glow a dim blue, yet still show the correct colour when driven. The 8 to 12 bit gamma mapping does IMO give better colours at lower brightness, however I don't think in reality anyone would pick the difference with out comparing them side by side next to a typical WS2811. I currently can't think of any reason other than potentially price or availability to use anything other than GS8208 (although perhaps someone can enlighten me of one). For my arches, I opted for 60l/m individually controllable GS8208 IP67 strip and very impressed with the quality of the product and performance. In the photo below (1), I feed power and data in the left, and inject power at the end. Each tree has 50 GS8208 bullet nodes, each star 20, each arch 120. When I didn't have power injection on the right, last 20% of the last arch and far right tree were a bit glitchy, but 210 bullet nodes + 240 strip nodes from a single feed is pretty good. I ordered the strip cut to length with 15cm tails on each end. Very glad I did this, saved a lot of time. These came to $17.60 each (USD + sipping). Also for the roof lines (2) I was prepared to have to add power injection at the end, but found I didn't need it, so left it out. That made of 351 GS8208 square nodes (114 + 108 + 129). * NOTE * - I'm running my display at 40% brightness, which is IMO easily bright enough, even with the street light for the pedestrian crossing just out of shot to the right.

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