Hi all: I'm looking to buy a replacement HPS bulb. I found 400w HPS bulbs on this website for under $10. Someone check it out and see if it's legit. Everywhere else I look is trying to get $50+ for HPS bulbs, so this just seemed to cheap for me to just rush and buy. Any help would be appreciated. http://www.lightingcloseout.com/product_detail.cfm?ProductID=310&CategoryID=2
