I have a 4 x 5 foot grow room using the Haight 800, my yield was just over 6oz on my first run, should be better this next run. I think that compares to about a 600W HPS, so they may be hyping it a bit - but not that much really. It's a long way from being like a 1KW HPS though.
Hello leduser,

I would love to see a Haight 800, just out of curiosity to see how they cool 190w of LEDs. And also to see what diodes they are using, they point to the competions' Cree's but make no mantion of what they use. Hyping it a bit? Please, it's not even close to a 600w HPS if that is what you're getting. Check out what they claim for coverage area, you could not cover what they claim with a 1kw HPS.

I do know that 2 Procyons over a 3x3 aero/fog tray, doing SOG size plants will out produce the Haight that you have, by a substantial amount. And 1 TI pro-bloom over the same tray would do a little better.

In my personal grow I have 740w of hybred LED/T5 that out produces a 1000w HPS, and in another grow I've run 2 TIs of 660w total head to head with 1000w (realy 1150w w/ballast).

LED grow lights would be a lot better if the marketing types could be a little more honest. BTW it is interesting to note that only a couple of mfg's have ever submitted thier lights to an independent tester to be evaluated. Check out Experiments with Hydroponics, Aeroponics, and LED Grow Lighting
