I use mars, I have 2 192x3 watt reflectors.. Killer lamps.. Ive ran those reflectors non stop for over 16 moths now.. I also use a 600 HPS Hurtilux and a mars 900 for a side lamp.. those mars have paid for them selves about 8 times.. Id like some new LEDs at some point maybe next year 2017.. LEDS teckkie is in such a weird place right now!![/QUOT Cool, I have 2 - 600 Apollo Horticulture hps/Mh and a king 1000watt double chip LED, it was only 300$ on Amazon, figured I can't go wrong for that price, I am aware that it's not a top of the line light, but it works great in conjunction with the others, I have it off to the side where I loose the spread from hid lights, right above my n.l.x chronic fem from Spanish seeds Co. She gets the full power of led plus the spread of hps. I sanitize my room every 3 weeks, I never have mold or bugs, EVER. Here's a couple pics from yesterday while they were out to get a good size reference.
