[QUOTE="TerryK, post: 115414, member: 32169"] Putting distances on the home photo will help. Perhaps wire gauge sizes too for the power injection. Pixel types and number of helps too; bit easier than having us reverse-link to your selection. The pixels you indicated are 18 AWG Regulated which is good. The formula that Jay mentioned is what I use (NbrPixels * AmpEach * DrvLvl) other than I use either .05 or .055 rather than .06. This will get you in the ballpark for supply requirements. Pixel drive level too. I design for 80% but that is really really bright (the evil side of me sometimes whats to flash the neighborhood). Most individuals indicate drive levels in the 30% plus a bit range. Something that is difficult to explain and is not often mentioned is particular implementations of power injection and supplies and their capacity do not always fit together well. That is, rather than adding another 'x' supply, it is sometimes better to obtain a lesser quantity of larger capacity supplies. As such, supply selection is usually later. I am not a fan of custom strings as it seems something always needs adjusted. I would suggest pixels in 100 pixel strings and shorten/lengthen as needed. Also, being in the US, you might look at RGB Man for the pixels. Wired Watts is good for the pigtails/connectors. I use Meanwell RSP supplies and it is a toss-up between Mouser and Amazon for cost. Amazon supplies most of my 'little' items; fuses, power blocks, heat shrink, and such. A lot of individuals use xConnect connectors, I started to and have moved to something different that 'fits' me better. [/QUOTE]

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