I have a TCSS Lux V Royal-Blue kit, and I'm planning on getting a MR soundboard for my custom saber, but I heard it has to go through a relay to power the Lux V. I'm new to electronics and wiring, so what exactly is a relay? Will my saber still retain the ame brightness going through a board not made for it? And finally what are the differences between the 3-cell and 6-cell MR drivers and which would be better for my LED? sorry but I couldn't find much info on these topics. Any help is greatly appreciated.
