To respond to dwwojcik, when you get far enough in Tekkit, you fell as though you've "beat it", you have the last step in every mod the biggest house the best armor and unlimited everything (power flowers). And to go to svenco, now if you are using redstone lamps, all they require is a redstone current on any side (top is preferable), and then a redstone lever with some red wire (RedPower Mod, that may not be quite what it is called) going up to them. If you are using something else, LV Cables (Three refined iron across I believe) have the least power loss over great distance, however, your Power must be stored in a Bat Box or Put through a LV transformer to use that.
