600w LED vs 600w hps + 400w mh

Just as the title says.

I am going to be doing a small 15 plant grow, aeroponically, with the aerojet system(http://www.texashydroponics.com/shop/product.php?productid=1794&cat=48&page=1).

Would a 600w LED(says it mocks two 1000w hids), and maybe one LED UFO do me fine? OR should I stick with the 400 + 600 HIDs I already have? Would love to save on the cost+heat.


I believe this is the 600w in question: http://www.chinazrh.com/wholesale-600w-led-grow-light-p-2382.html

i personally would always go for HIDs. i have never tried LED but i have yet to see them do as good or outperform an HID.

in order to replace the lights you have you would need a 2-3k LED unit, at this time. The cheap knockoffs will just not cut it.
