one more word of advice/caution - handle the bulbs with dry, clean hands - or better yet - use latex gloves (moisture is what causes the bulbs to pop) - that's another great thing about getting the glass cover - protects the bulbs when/if you foliar feed.
thanks Lacy -- you are also very helpful. I saw your questions on the other thread - and figured you were trying to chill folks out - which is why i responded in a joking manner (metric adjustable wrench indeed). i don't have anything against fights - but i prefer they be over something worthy - which is a pretty rare situation.
i did want to mention that i think you'll know what to do to set up your light intuitively (once you see it) but if you run into any troubles - drop me a line. i'll be happy to help if i can.
and oh yeah .... you'll be shocked at how fast your plants grow with all that light. no really you will!
