WalMart is selling twin-tube flourescent fixtures for about $9 apiece ... the lamps themselves are less than $4 apiece ... so, for a 6-tube setup, you're looking at about $48 plus tax ... you won't buy a 400-watt HPS for anything near that ... mine cost over $300, and it was a bargain ... beware of lamp setups on eBay ... if it seems like a good price, read the fine print carefully ... most of those cheap ones are 'used' and 'refurbished', etc ... they're sometimes converted street light setups, with a gazillion hours on the ballast ... this is about all I have to add ... :smokin:
