I think going through the Nether is the only way (Simple way) just equip yourself with some Nano armour (http://technicpack.wikia.com/wiki/Nano_Suit) and you should be good after you get some Glowstone you can do your system much easier by using Energy collectors (http://technicpack.wikia.com/wiki/Energy_Collector) to produce glowstone.
Hope this helps
