Grow room question

I got this idea from reading another post about LED lights.. has anyone else tried a grow with them? I dont want to go spending 800 bucks on a setup when i have a perfectly good hps going... but thinking this would be a more discreet way as no one can come in my room! :/
The area i have now is in the corner when blankets over it...
The new location would be in my closet.

in my opinion leds dont add up to hps pllain and simple you would be better off with 2 400watt hps than all those led
