LED advice? Setup advice?

I live in hawaii and im looking to setup an operation indoors. I have been looking at possibly buying a 350w high quality led lamp. I am pretty set on led because of the cost of electricity and heat and can afford the inital setup cost of led. what i am wondering is if anyone has any advice on a good company (that ships to hawaii hopefully cheap) that i could go to. i have been looking at http://www.hydrogrowled.com/Default.aspx and http://www.myhydroponicgardening.com/resources/bigLEDgrowlight. my goal is to do at least 7 plants and was wondering how much i could yield from 7s and if that even sounds logical with a 19''x19'' 345w LED from hydrogrowled.com and would this be the only light i need for veg and blossom. i need to know how big of an area (like 10'x10') i would need because i would like to build a mylar tent as well. this is my first real operation on my own and i have alot to learn and read thanks for any help

any help please?

there are a ton of lights out there. some are good some are bad... calling the company and speaking to someone is a very good way of finding out if they know what they are all about... on the specs for the light itself it says good only to 6x4 feet during flowering, so call it 5.5 x 3.5 in reality... 7 monster plants will be difficult to fit into the space, but with some supplemental lighting (or two lamps) you'll be pulling in monsters! good luck. post pix and journal the hell out of it... leds are cool!

thank you for the info.
