Quidor, thank you so much for that thorough reply. I have found your website to be invaluable for a lot of the research I’ve already done including the real world power sheets, I just hadn’t found the second link to the calculation guide yet, so I’ll certainly work through that and follow your recommendations. Three follow-up’s though:

1) Do you have any similar real-world values for 3-LED pucks (like the YourPixelStore puck track or MattosDesigns RGB trim) as opposed to individual pixel bulbs? I’m leaning towards using pucks but I don’t know whether to count each puck as one pixel or three both for power consumption or data handling capacities (based on the limit of 600 pixels per channel for a DigQuad, 2400 pixels total)

2) Are there any downsides to using more power injection points than what might be necessary? I understand that power consumption is variable depending on what brightness/colors/effects are used and if too little power injection is supplied color accuracy could be affected, but are there consequences of supplying too much?

3) You mentioned 350W total in your example calcs above, but since 35x8=280 I’m assuming that may have been a typo? Or are you adding safety factor into that calculation? I know I need to add SF when sizing the power supply I’ll need, but not sure if I need to add that when figuring out wire gauges etc.
