sorry for the confusing title but this is a battle royal of lumens, if you will. i am in the planning stages of a new frank (for those of you not following the grows, frank is the name given to my pet project by my wife, a la frankenstein, a mix-mash pile of parts i put together).
the dimensions of the new box are gonna be 45.5" x 21" x 24" (l x w x h). i was thinking about using two 6 bulb (~36", each bulb is ~1600 lumes.) light bars with Y splitters and 26w CFLs of the appropriate temperature. then while at lowes i saw a 70w HPS security light for $35 (forgot to check the lumens). they also have a 150w HPS for $85 (~16,000 lumens).
and i guess the final option would be a 400w HPS found online for around $130.
my question is with the dimensions that i'm working with, what lighting would work best? i was thining possibly two of the 70w or 150w HPS'. or the one 400w HPS. i just don't know how well the one bulb will cover the dimensions.
any thoughts, ideas, input or suggestions? thanks in advance.
and yes, i'm aware new cooling will be needed!
