    Based on the fact that the HID fixture uses an actual 600W and the Mars pulls 285W, it really should be obvious which one will produce more growth.
    HID is hard to beat for low initial cost and decent efficiency. The one MAJOR hurdle is getting ridi of the eheat generated by the fixture. If you have the capability to manage thermal load, I'd stick with the HID. To produce a comparable fixture using top shelf cobs or SMD's it will run at least $1/watt if you DIY. Using best diodes will allow you to reduce power usage by 1/3 to produce the same amount of light energy.
    Bottom line on lights-if you can deal with the heat from a HID go that route. It only makes more sense to invest in leds if you can get much better efficiency then a HID so build the best you can afford.
