LED

Post by reni »

Hello
I would like to know which type of RGB LED strip I can use with portable 12V battery pack. I want to be able to make the LED sequence change with switches not ONE MODE button that is sequential. I want to address LEDs at will and change color etc by just changing the state of an INPUT switch. If I have 3 inputs then I have 10 possible configurations. The micro controller can tell the strip what to do. Bottom line, I want to program the sequences and select them at will.

Most of our digital LED strips run on 5v. We do have a few types of large pixel strands designed for 12v:

All of our strips are easily controlled from an Arduino micro-controller. The libraries for these strips include sample code to get you started and there are plenty of tutorials online as well.

Does the 5V LEDs provide as much or brighter luminescence as the 12v LEDs? Since I am running from battery packs, which of the two prvides greater energy saving for longer operation? I guess it would in part depends on # of LEDs turned ON at a time! What else?

The 12v pixels are larger and have multiple leds per pixel. So each pixel is brighter, but consumes more power. In terms of energy efficiency (light output per watt) they should be about the same. Power consumption is mostly determined by how many leds are on, and at what power level you are running them.
