keep your hps . I watch and read lot of videos . only light that will give you slightly more par out put then hps is the kind led and its way over your dollar amount and in my opinion its 4 times to much its not worth it you will never get your investment back well mabe in 4 years if it does not break . I use Philips led tubes in veg have ok results but mh is far superior so the hps will be as well . but I an not comparing them equally . the mh I use is 1000 watts lol and the led only is about 120 watts . so if I could get this many leds in the same space the led would win . 1000 watts of them
