I'd go with the HPS HIDs....and run them at 240v....

I've read good things about the LEDs....but have also read that the fans and power converters don't last as long as the diodes do.... So LED lighting companies sell the idea of never having to replace the diodes....but they fail to mention how much it will cost to maintain the lamp once the fans and converters start to fail....again, that's what I read....but dont know from personal experience....

Wish I had $15k to put towards a grow room.... I know exactly how I'd set it up too.... Good luck with your grow :thumbsup:....:jointsmile:....

Read up on Digilux bulbs....
