[QUOTE="scamper, post: 81256, member: 22285"] Power injection is basically hooking up another power wire to the string. You have to realise that each string at full white would draw about 3amps (very rough basic guide only) The voltage drops along the way down the string and by the time it reaches the end can get so low that instead of being white, you will get a yellowish colour. Or worse, not enough power to even run the chips in the pixels. So what you have to do is "inject" some more power. This is done by running some 2 core flex to the + and - at the end of the pixel string straight back to the power supply. And you need to do this every string. The reason most people don't run the power from the controller as Shell says, is that most boards can only handle around 5 amps per channel while you can run up to around 13 strings, therefor you would draw anywhere up to 40amps. It is just not possible. As Brad said, the manual is your friend, and then if you need an answer straight away, go into chat, there is usually someone lurking around that can help. ** please note, the figures I have given are very ball park just to help explain and will differ from string to string and controller** [/QUOTE]

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